Description




BACKGROUND




1. Field of the Invention




The present invention generally relates to data storage and retrieval and more particularly to the storage management of data across multiple time zones.




2. Description of the Related Art




Conventional methods require a user to know ahead of time where exactly data is stored in order to retrieve it. The user needs to be aware of the operating system and server platform type from which the data was originated. In addition, the user needs to know the media type (magnetic disk, optical, tape, or other media) the data is stored on. Moreover, the user needs to know of the exact media on which the data is stored in addition to when and where it was stored. Systems that have been developed to address the problems of this nature have encountered challenges when storage management occurs across multiple time zones.




Many other problems and disadvantages of the prior art will become apparent to one skilled in the art after comparing such prior art with the present invention as described herein.




SUMMARY OF THE INVENTION




Various aspects of the present invention may be realized through a storage management system that includes a processor that is configured to maneuver digital files among a plurality of storage devices according to commands that are received from software programs that operate on the processor. The software programs may include a file browser operating on the processor. The file browser is configured to display selected ones of the digital files that are maneuvered among the plurality of storage devices and to enable selection of specific digital files in the storage management system when requested by a user. The storage management system also includes a retrieval control operating on the processor that receives commands from the file browser and provides the file browser with information regarding the digital files selected by the user. The information is gathered during the time that the digital files are maneuvered among the plurality of storage devices by the processor. Also included is an index in the retrieval control that stores the gathered information regarding each of the digital files for quick access when requested by the file browser. The index information is configured to account for digital files from storage devices that are located in different time zones.




The file browser of the storage management system may include a tool bar that allows access to particular characteristics of a digital file that has been stored in at least one of the plurality of storage devices. The particular characteristics may include digital file creation date, digital file backup dates, and digital file access dates. Among other things, the file browser may have a view menu that offers a user an option to select a date in which to begin displaying a history of a selected digital file(s).




Other aspects of the present invention may be realized through a data retrieval system that includes a computer system having a processor that supports operation of at least one software application that is used for retrieving data in the computer system. The data retrieval system also includes a plurality of storage media that are located in at least two time zones and that communicatively coupled to the processor. The plurality of storage media have data stored in at least one of the plurality of storage media. The software application has a retrieval module for retrieving data from the plurality of storage media. The retrieval module accounts for differences in the at least two time zones in which the plurality of storage media are located. Finally, a storage and backup map is included that indicates to the retrieval module a particular location of the data that is to be retrieved by the retrieval module.




In some embodiments, the software application of the data retrieval system includes a tool bar that allows access to particular characteristics of a file that has been stored in at least one of the plurality of storage media. The particular characteristics may be file creation date, file backup dates, and file access dates. The software application may also include a view menu that offers a user an option to select a date in which to begin displaying a history of a selected file(s).




Still other aspects of the present invention may be realized through a storage management system that includes a processor that is configured to store and maneuver digital files among a plurality of storage devices according to commands that are received from software programs that operate on the processor. A software program operating on the processor is configured to store selected ones of the digital files that are to be maneuvered among the plurality of storage devices in the storage management system. The storage occurs when requested by a user. A storage control operates on the processor and receives commands from the software program. The software program acquires information regarding the storage location of each digital file. The information is gathered during the time that the digital files are maneuvered among the plurality of storage devices by the processor. An index is associated with the storage control and stores the gathered information regarding each of the digital files for quick access when requested by the storage control. The index information is configured to account for digital files from storage devices that are located in different time zones.




The plurality of storage devices of the storage management system may include a plurality of storage media that are selected from the group consisting of magnetic tape media, magnetic disk media, and optical medial. The storage control of the storage management system often includes a manager module that interacts with a media module to compile the index to track the location of stored digital files. The storage control may also be configured to migrate selected digital files among the plurality of storage devices according to the particular storage policy. The particular storage policy is selected from the group consisting of storage sequences, storage logic, initial storage sequence selection criteria, storage sequence reselection criteria, and storage sequence adaptation criteria. The initial storage sequence selection criteria may be selected from the group consisting of user directed override, user profile, application, file type, user network location, and available storage space. The storage sequence reselection criteria may be selected from the group consisting of specific file usage history, file type usage history, user profile, user network relocation, available storage space, and added storage media. The storage sequence adaptation criteria may be selected from the group consisting of specific file usage history, user profile, user network relocation, available storage space, and added storage media.




Of course, other embodiments will become apparent to those of ordinary skill in the art upon viewing the present disclosure.

DETAILED DESCRIPTION OF THE DRAWINGS




An exemplary description of the present invention is a retrieval system that allows end users to view and access in the logical format that they commonly see in their applications or systems. The users just have to define the general outline (such as part of the file name or file path or approximately when the data may have existed or the desired point-in-time view of the data) of the data that they are looking for. The data will then be retrieved and presented to the user regardless of the media type that it was stored on or platform type on which it was controlled. The user can then select the exact version of the data desired. However, retrieving time dependent versions of data is complicated when the data to be retrieved is stored on a computer system that is located in a different time zone than the computer that is requesting the data.




It is to be understood that the present invention applies to both retrieval and storage systems, but for ease of understanding the principles according to the present invention, the figures pertain to a retrieval system. However, those skilled in the art and viewing the present disclosure will understand that the time zone characteristics of the present invention may apply equally well to a storage system.





FIG. 1

is a block diagram of an exemplary embodiment of a retrieval system


100


that operates according to principles of the present invention. The retrieval system


100


includes software applications


102


that a user interacts with to retrieve data from various storage media. The software applications


102


communicate with a retrieval control


104


that determines where to retrieve data from the storage media based on instructions and information available in a storage and backup map


106


. The retrieval control


104


typically receives data from the storage media that the software applications


102


have requested. When the software applications


102


request data, the retrieval control


104


determines whether to retrieve the data from a first storage media


108


, a second storage media


110


, or any number of other storage media down to an nth storage media


112


. The various storage media


108


,


110


, and


112


may be located on a single computer system, distributed across a wide area network, such as the Internet, etc. When the storage media


108


,


110


, and


112


are distributed across the Internet, their actual physical locations may be in different time zones, for which certain adaptations are made as discussed in more detail herein. The retrieval control


104


locates the data to be retrieved according to storage information available in the storage and backup map


106


and the retrieval control


104


is then able to determine which storage media the data will be retrieved from regardless of migration of the data after initial storage in the storage media.




For example, the retrieval control


104


may retrieve data from the second storage media


110


that was initially stored in the first storage media


108


and, unbeknownst to the software applications


102


had since migrated to the second storage media


110


. In addition, the retrieval control


104


could retrieve data from any other of the storage media which are illustrated. The storage and backup map


106


is continually updated when data is moved between storage media, e.g., from the first storage media


108


into the nth storage media


112


. Of course, the data could be moved in either direction and between any of the storage media while the storage and backup map


106


is updated with the changes. In this manner, the software application


106


is configured to request and retrieve data from the storage media by means of a simple request for the data. Advantageously, the user is not required to know the latest location of the data in the storage media to request the data. Thus, retrieval of data from many types of storage media is available without assistance beyond the retrieval system


100


itself.





FIG. 2

is a block diagram of an exemplary retrieval system


200


that operates in accordance with the principals of the present invention. The retrieval system


200


includes a software application


202


and a retrieval manager


204


that interoperate to retrieve data from different storage media in the retrieval system


200


. The software application


202


includes an interface module


206


and a backup retrieval


208


. Thus, when the software application


202


desires to retrieve data, it begins by sending a request through the interface module


206


where the retrieval manager


204


then accesses a storage and backup map


210


to find the exact location of the data that is to be retrieved. The data may be located in a first storage media


212


, a second storage media


214


, or any number of storage media down to an nth storage media


216


. As discussed with regard to the retrieval system


100


, the storage media


212


,


214


, and


216


could be physically located in different time zones. The data that is to be retrieved may be stored on any of the storage media, and over time, may migrate from one storage media to the other. The storage and backup map


210


tracks the migration of the data so that the current location of the data is always available for access by the software application


202


.





FIG. 3

is an illustration of an exemplary file browser


300


that can be used for viewing data prior to retrieval of the data from the retrieval systems


100


or


200


. The file browser


300


includes a tool bar


302


that enables a user to access the data in various manners. Although the file browser


300


can be implemented in various manners, the file browser


300


is generally divided into a folder hierarchy


304


where folder names can be viewed and a file list


306


where particular files of the selected folder are displayed. The file list


306


includes a file information bar


308


that can be dynamically modified for viewing different information concerning the files of the file list. Corresponding to the items selected for viewing in the file information bar


308


are, first, a column reflecting the name of the files that exist in the particular folder that has been selected. In the embodiment of

FIG. 3

, foldername2 has been selected in the folder hierarchy


304


and filename1, filename2, and filename3 appear as the files in the foldername2. Each of the files in the file list


306


includes backup information which includes the backup date and time of the filename. This information is listed in a second column of the file list


306


under the title “backup version date” from the file information bar


308


. Filename1 shows three different backup dates and times. This is because a user has opened the versions of filename1 to show other than the latest version that has been most recently saved. For example, filename2 shows the default display under the backup version portion of the file information bar


308


. This is the default because a plus sign is shown and other backups that have been completed are not shown with regard to filename2. Although only 3 backups are indicated for filename1, other files that are displayed in the file list


306


may contain many more backups based on the history of the file. The third column indicates the size of the files at the time they were backed up.




As stated, the backup information for each of the files in the file list


306


is only an exemplary representation of the information that could be displayed. However, for ease of understanding the present invention, backup information will be used herein. For example, the backup information of filename1 is displayed in the file list


306


. Although not apparent from the backup list, each backup may be physically located at a different storage media due to file migration in the retrieval control of the computer system. Time zone difficulties may arise when the backup changes its physical location to a storage media of another time zone prior to the backup being accessed, i.e., the backup is migrated to a storage media that is located in a different time zone than where it was originally created. This is a difficulty because a backup that was created at 9:17 AM in the first time zone may have been moved to another time zone where no backup exists with a 9:17 AM time stamp. This difficult is resolved when the retrieval system changes the backup time indication to an appropriate time for the backup when the backup is moved into a storage media of another time zone.




In another embodiment, the backup retains its time stamp regardless of the time zone into which it is moved, however, the difficulty with the time zone change occurs when the backup is to be migrated at a particular time in reference to the original time stamp in the first time zone. For example, the original backup may have occurred at 9:17 AM and a scheduled migration is 48 hours from the time of the backup, which would be two days later and at 9:17 AM on the original system. In the event that a migration occurs that places the backup into another time zone prior to expiration of the 48 hours on the original system, the scheduled 48 hour migration must occur at a different time than 9:17 AM on the current system, e.g., the migration on the current system would need to occur at 10:17 AM on the current system if the current system is in a time zone that is one hour different than the original system. In other words, to correspond with 48 hours from 9:17 AM on the original system, the migration needs to occur one hour off from 9:17 AM on the current system. Of course, if the time zone difference were two hours, the migration would need to occur two days later and two hours off from 9:17 AM on the current system.




In one embodiment, backups are always performed by the original system and the file retains its time stamp from the original system regardless of the moves that the file makes after its initial storage by the original system. In this manner, time stamps of backups correlate to the same time zone regardless of file location. The retrieval control/manager


104


/


204


is configured to recognize that files to be retrieved may have time stamps that are inconsistent with the time system on which the file is located.





FIG. 4

is an exemplary file browser


400


illustrated in accordance with principals of the present invention. The file browser


400


includes a toolbar


401


similar to the file browser


300


and specifically, the view menu


402


of the tool bar is illustrated to indicate that a user may select what portions of a file to view. As illustrated, a user may select a detailed display of a file and a date for which the user desires to view the history of the file. For example, if the user selects “as of date” as illustrated, a view “as of date” box


404


appears on the file browser


400


. The user may select the date of interest for file viewing. For example, the user may desire to see all backups that have been made of files that are in foldername2 as of Sep. 12, 1999. When the user makes the selection, the user will press an okay button


406


and the files that are displayed in file list


408


will only include those files which existed prior to Sep. 12, 1999. Thus, a quick comparison of the files shown in the file list


408


to those files shown in the file list


306


, show dates earlier than Sep. 12, 1999. Of course, the view “as of date” box


404


could be modified to include a time selection as well as a day selection, but for ease of understanding only a day box is illustrated. If the user has selected the view “as of date” box


404


but decides not to view a particular date, the user may press a cancel button


410


to return to the regular features of the file browser


400


. Of course, differing time zones may be accounted for by configuring the file browser


400


to ignore time differences that are introduced when files are accessed from computer systems programmed for a different time zone.





FIG. 5

is an exemplary file browser


500


where an exemplary find mechanism is illustrated. The file browser


500


has a tool bar


501


that includes a find menu


502


. A user may select the find menu


502


to produce a find dialog box


504


. The find dialog box


504


includes a folder selector box


506


where the user may select a particular folder in which to search for a particular file. After selection of the particular folder to search, the user may enter a file name for which to search. This file name would be entered in a file name search box


508


. Of course, the file name may be entered with wild cards or other search techniques which are commonly available in most operating systems. After a file is entered into the file name search box


508


, the user may press a find button


510


and the search results are displayed in a found file box


512


. The user may use a scroll bar


514


for scrolling up and down the file list that is displayed in the found file box


512


. To avoid time zone problems, relevant information associated with the files of the found file box


512


is located in the storage and backup maps


106


,


210


, or equivalent module, and is accessible by the file browser


500


.




When a user finds the file which they were searching for, the user may press the open button


516


to view the file. A backup button


518


is also available for a user to list the backup information for the particular file which they are searching. When the backup button


518


is pressed, a backup window


520


appears on the file browser


500


and a list of backup dates


522


is shown for the user to view. The user may scroll through the list of backup dates using scroll bar


524


, but other techniques may be available for searching the list of files that show up in the backup box


520


. When the user finds a particular backup date of interest, the user may open that file using an open button


526


. When the user has completed viewing the files in the backup box


520


, the user may cancel viewing the backup box


520


by pressing a cancel button


528


. A cancel button


532


is also available to cancel out of the find dialog box


504


completely. If the user is in need of further assistance the user may also press a help button


530


. Upon pressing the help button


530


, the user is given help in formats similar to a typical operating system help function.





FIG. 6

illustrates an exemplary standard Windows application


600


and how the retrieval system of the present invention may interact therewith. The standard Windows application


600


may be an application such as a word processing application and a file menu


602


may be entered when a user desires to open a file. The user will select the open option of the file menu


602


and a file open application will intercept the request to the operating system to open a file open dialog box


604


.




The file open box


604


includes a folder selector box


606


where a user may enter the name of the desired folder to enter. Upon determining a folder name, e.g., foldername2, a file list


608


is displayed. The file list


608


includes a file information bar


610


that is modifiable but is shown including a name column and a backup version date column. As with other embodiments, the file names may be listed in the file list


608


with a default backup version date of the last backup that was completed for each file or the last save that was performed on each file. If a user desires to see a detailed history of backup dates, the user may press a plus button


622


which will then change to a minus button


624


as illustrated in the file list


608


. A scroll bar


612


is illustrated as a tool for a user to scroll through different file names to find the file which the user may desire to retrieve.




When a user has found the file of interest, the user may press an open button


614


to open the particular file. If a user is unable to find the desired file or desires to exit the file open dialog box


604


, the user may press a cancel button


616


to exit the file open dialog box


604


. The user is also able to press an information button


618


to get further information concerning each of the files. The information button


618


may allow the user to select particular options such as an “as of date”, a specific date, or even a range of dates. The file open dialog box


604


is illustrated with a help button


620


that can also operate similar to common operating system help buttons.





FIG. 7

is an exemplary retrieval system


700

702


is illustrated and is similar to the software application


202


. The computing system


702


includes a software application


704


that interacts with an installed file system


706


and a helper application


708


. The helper application


708


includes a backup retrieval module


710


for interacting with a retrieval manager


712


. The retrieval manager


712


interacts with storage media by obtaining information from a storage and backup map


714


. In this manner, the computing system


702


can retrieve data from any one of a first storage media


716


, a second storage media


718


, . . . and nth storage media


720


. As previously explained, data on the storage media may migrate from one storage media to another depending on various storage policies.





FIG. 8

illustrates an exemplary Windows application


800


such as Windows Explorer. The Windows application


800


includes many of the same features as are commonly available on most Windows application. However, if the Windows application


800


is Windows Explorer, only a single parent directory rather than numerous drives are illustrated in a folder hierarchy


802


on the left half of the windows application


800


. On the right half of the Windows application


800


is illustrated a file list


804


. The file list


804


includes a file information bar


806


that is dynamic and may be changed to reflect various pieces of information regarding the files in the file list


804


.




When a user views a file of interest from the file list


804


, the user may access an operations menu


808


that is available by right clicking on the file of interest or through other standard Windows operations. The options menu


808


is a standard Windows option menu but includes additional features such as a “backup” selection. If the user selects the backup option from the options menu


808


, a backup dialog box


810


opens. The backup dialog box


810


includes a list of dates for which the particular file was backed up over time. The different dates may be viewed through movement of a scroll bar


812


by the user. If the user finds a file of interest in the backup dialog box


810


, the user may open the particular file by clicking on the file and then clicking on an open button


814


to open the file. To open the file, the user may also double click on the file of interest as is commonly done in standard operating systems. Those skilled in the art and viewing this disclosure will understand that various other options may be available for selecting a particular file to view. When the user is complete with the backup dialog box


810


, the user may press a cancel button


816


to exit the backup dialog box


810


.





FIG. 9

illustrates another exemplary standard Windows application


900


as it may interact with the retrieval system of the present invention. In the Windows application


900


, a file menu


902


is used to open a file. When a user selects the open option of the file menu, a file open dialog box


904


appears on the Windows application


900


. This file open dialog box


904


is not the standard Windows operating system dialog box but is produced by an application that intercepted the command from the open menu


902


when the user selected it, thereby allowing the file open dialog box


904


to be activated rather than the standard Windows open dialog box. The file open dialog box


904


includes a folder selector box


906


where the user may select a particular folder to find the file of interest to open. Upon selection of the appropriate folder in the folder selector box


906


, a list of available files is shown in the file open dialog box


904


.




The file open dialog box


904


includes a file information bar


908


that is adjustable to reflect the information that the user desires to view in the file list. In the file information bar


908


illustrated in

FIG. 9

, only a name column and a date column are illustrated, but the options could be modified according to a user's needs. The files listed in the file open dialog box


904


can be viewed through use of a scroll bar


910


. When the appropriate file is found, the user may select the file, in this example filename3, and open the file immediately with an open button


912


. However, the user may desire to view backup copies of filename3 and therefore right click on filename3 to select an open backup dialog box


914


.




The open backup dialog box


914


lists the backups that have been performed for the filename3, and the user is able to scroll through these backups to find the appropriate backup date by using a scroll bar


916


. Of course, other options for finding the appropriate backup file are available and this illustration is exemplary only. When the appropriate backup date is found, the user may press an open button


918


to open the version of the file that has been selected. When the user has completed using the open backup dialog box


914


, the user may press a cancel button


920


to exit the window and return to the file open dialog box


904


. At this point, the user may press a cancel button


922


to exit the file open dialog box


904


. A help button


924


is available as in a manner that is similar to standard operating system help buttons.





FIG. 10

is a block diagram of an exemplary retrieval system


1000


that is illustrated in greater detail than earlier retrieval systems of the present disclosure. The retrieval system


1000


includes a computing device


1002


, a computing device


1004


, and a computing device


1006


that are interconnected and communicate with one another wia a network


1007


. The computing device


1006


includes a magnetic disk media


1008


for storage of data that the computing device


1006


receives from the computing device


1002


.




The computing device


1002


includes software applications


1010


and installed file system


1012


. The installed file system


1012


works with an interface module to retrieve data in the retrieval system


1000


. When data is to be retrieved for the software application


1010


, the installed file system/interface module


1012


begins interacting with a retrieval manager


1014


of the computing device


1004


. The retrieval manager


1014


includes a master storage and backup map


1016


. In this embodiment, when the software application


1010


is directed to retrieve data, the data is sent to the installed file system/interface module


1012


and then to the software applications


1010


. To find the location of the data that is to be retrieved, the retrieval manager


1014


views the information in the master storage and backup map


1016


. The information from the retrieval manager


1014


is passed to the installed file system/interface module


1012


so that the computing device that knows the exact location of the data is then known and can be retrieved from the storage media.




For example, computing device


1006


may be where the system looks to retrieve the data of interest. The computing device


1006


includes a media module


1022


having a data index


1024


that would indicate the specific location of the data to be retrieved. This data will be stored in a storage media such as the magnetic disk media


1008


or optical media


1026


. Of course, other types of storage media are available and more than two storage media could be available from the computing device


1006


. When the data is found, it is then passed back to the software applications


1010


through the network


1007


.




The retrieval manager


1014


of the computing device


1004


may indicate that the data is stored at computing device


1028


based on the information found on the master storage and backup map


1016


. In this case, the retrieval system


1000


must look to a media module


1030


of the computing device


1028


where a data index


1032


indicates the exact location of the data to be retrieved. In this example, the data may be located in a magnetic tape media


1034


or other media. in addition, the retrieval manager


1014


may indicate that the data can be found by looking to computing device


1036


where a media module


1038


uses data index


1040


to find the exact location of the data on other storage


1042


.




It is understood that data may migrate from one storage media to another and the original location where the data is stored may vary over time. However, the movement of data is tracked by the respective data indexes


1024


,


1032


, and


1040


, so that wherever the data happens to be currently located, the software application


1010


may retrieve the data without undo delay or undesired assistance.




Multiple variations exist for the retrieval system


1000


as shown by components illustrated in dashed lines. Specifically, a manager module


1046


may exist in the computing device


1002


where it interacts with a media module


1048


to obtain data directly from storage media


1050


without having to interact with other computing devices. In other embodiments, a media module


1052


may be located in the computing device


1004


where data is found in storage media


1054


. In another embodiment, a manager module


1044


may be present in the computing device


1036


. Those skilled in the art and viewing the present disclosure will understand that numerous possibilities exist using the same concepts.





FIG. 11

is a block diagram of another exemplary retrieval system


1100


. The retrieval system


1100


includes a computing device


1102


, a computing device


1104


, and a computing device


1106


. The computing devices


1102


,


1104


, and


1106


interact to retrieve data through either a storage area network


1108


or a network attached storage


1110


.




For example, computing device


1102


includes a software application


1112


that interacts with an installed file system


1114


. The installed file system


1114


interacts with a media module


1116


that could indicate that the data to be retrieved is located in storage media


1118


. Alternatively, computing device


1104


includes software applications


1120


that interacts with the installed file system


1122


to retrieve data. For the computing device


1104


to retrieve data, the installed file system


1122


may have to interact with the computing device


1106


because the computing device


1106


includes a retrieval manager


1124


that includes a master storage and backup map


1130


. When the information for retrieval is located, the information is passed back to the computing device


1104


and to the installed file system


1122


.




This information may be used by the installed file system


1122


to locate information that is stored on the storage area network


1108


. Of note, the storage area network


1108


is connected to the computing devices


1102


and


1104


through a high-speed fibre network


1123


. For example, the data may be located on a magnetic disk media


1132


, optical media


1134


, or a magnetic tape media


1136


. The installed file system


1122


will have the information that the storage area network


1108


needs to access the specific information. On the other hand, the installed file system


1122


may understand from the computing device


1106


that the information to be retrieved is located in the network attached storage


1110


. If this is the case, the network attached storage


1110


has a media module


1138


where the exact location of the data is found in a storage media


1140


.




As illustrated by dashed lines, numerous variations may be made to the illustrated retrieval system


1100


. For example, the storage area network


1108


may include a media module


1142


so that the computing device


1104


does not need to communicate with both a computing device


1106


and a computing device


1102


to access data across the fibre network


1123


from the storage area network


1108


. In addition, a media module


1144


may be located in the computing device


1106


to alter the data accessing techniques of the retrieval system


1100


.




Dashed lines also indicate that the storage area network may be connected directly to the network


1146


of the computing devices and dashed lines


1148


indicate that the network attached storage may be connected through the fibre network


1123


to the computing devices


1102


,


1104


or across a regular network to the computing device.
