This application claims priority to European Patent No. 07118026, filed on Oct. 8, 2007, and entitled “Method and System for Improving Archiving of Electronic Documents.”
A main server in a company is often used to transmit emails from or to electronic devices, such as personal computers of users. As soon as a user needs to archive specific emails, one or more servers can store and archive these emails.
Despite the fact that storage capability is increasing, however, it is still possible to reach a maximum storage capacity. In such a case, users may have to store emails on their own personal computers or laptops for archival purposes. Users, however, often have more than one personal computer, or a personal computer and a laptop, or other electronic devices. As a result, users may have emails archived at different physical locations, and may encounter problems when looking for a specific archived email without knowing the correct archive location.
Further, users may need to retrieve a specific email relating to a specific subject. Presently, users are required to search among all archived emails relating to several subjects to locate the particular email.
In view of the foregoing, what are needed are tools for archiving electronic data that facilitate locating previously archived electronic files and other electronic data. Beneficially, such tools would facilitate identifying particular archived electronic files and data based on their particular properties and characteristics. Such tools are described and claimed herein.
Embodiments of the invention have been developed to provide improved tools for archiving electronic data that create a global archiving list and communicate the list to other machines.
Consistent with the foregoing, this disclosure is directed to a method for archiving electronic data in a network comprising a server communicating with at least two client machines. The method may include archiving the electronic data in a predetermined location of a client machine, and generating a local archiving list on the client machine. The local archiving list may include descriptive properties of the electronic data, as well as the predetermined location.
The local archiving list may be transmitted from the client machine to the server to generate a global archiving list on the server. The global archiving list may then be transmitted to other client machines in communication with the server. In this manner, each client machine in the network may store the location and descriptive properties of the archived electronic data to facilitate electronic data recovery.
A corresponding system and computer program product for implementing the above-stated method are also disclosed and claimed herein.
Some aspects of embodiments of the invention will now be described with reference to the drawings, in which:
It will be readily understood that components of embodiments of the invention, as generally described and illustrated in the Figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the invention, as represented in the Figures, is not intended to limit the scope, but is merely representative of selected embodiments of the invention.
Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the invention. Thus, appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment.
Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. One skilled in the relevant art will recognize, however, that embodiments of the invention can be practiced without one or more of the specific details, or with other methods, components, etc. In other instances, well-known structures, or operations are not shown or described in detail to avoid obscuring aspects of embodiments of the invention.
The illustrated embodiments of the invention will be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout. The following description is intended only by way of example, and simply illustrates certain selected embodiments of apparatus, methods, and computer program products.
The server 100 may generally be a workstation. The client machines 102, 104, 106 may be a personal computer, a laptop or any other device able to connect to a network (not shown). The server 100 may communicate with each client machine 102, 104, 106 through connection lines 108, 110 and 112. The server 100 may also communicate with other networks (not shown) in order to transmit and receive electronic data from other servers via the Internet, for example. Electronic data may include electronic documents and files such as electronic mail messages (“emails”). Each email may include descriptive properties, for example, date of the email, subject of the email, sender, recipient or recipients, etc.
Each client machine 102, 104, 106 may include an archiving module to process the archiving, as will be described below. Each client machine 102, 104, 106 may comprise a hard disk with a specific dedicated location, such as a local archiving folder 114, 116 and 118, respectively, for archiving emails on each client machine 102, 104, 106.
Each client machine 102, 104, 106 may also comprise a local archiving list in order to classify the content of the local archiving folder 114, 116, 118. The content may include emails archived in the archiving folder 114, 116, 118 of a corresponding client machine 102, 104, 106.
In some embodiments, the local archiving list comprises three kinds of descriptive properties. A first descriptive property may relate to the archiving folder 114, 116, 118, such as the path of the folder, size of the folder, etc. A second descriptive property may relate to a date of creation when storing a first email, a date of update when electronic data is subsequently added for archiving in the local archiving folder, a date range of the updates, or a last update date, for example. A third descriptive property may include one or more descriptive properties relating to the email, such as the sender, the recipient, or the subject of the email.
The server 100 may comprise a global archiving list, which includes a replication of each local archiving list, as will be described in more detail below. The global archiving list may enable classification of each archived email on each client machine 102, 104, 106. A process in accordance with one embodiment of the invention may include a number of steps, which will now be described in detail.
As shown in
In a step 204, the archiving module may register, for example, first, second and third descriptive properties of the archived email in the local archiving list. In some embodiments, as mentioned above, the first descriptive property may refer to the path for the storage location of the email. The second descriptive property may refer to the date of creation of the archiving folder 114, 116, 118, and to the date of archiving the first email. The third descriptive property may refer to the sender, the recipient and the subject of the email.
In a step 206, the archiving module of the client machine 102 may launch a replication of the local archiving list to the server 100. The server 100 may replicate the local archiving list of the client machine 102, 104, 106 and keep the replication of the local archiving list in a global archiving list. As a result, the global archiving list may include the same details as the local archiving list of the client machine 102.
After this replication, in a step 208, the server 100 may replicate the global archiving list on the local archiving list of other client machines 104, 106. This replication on other client machines 104, 106 may allow each client machine 102, 104, 106 to have the same information as the local archiving list of the original client machine 102. This may enable the other client machines 104, 106 to locate the first email stored on the original client machine 102.
Each time an archiving module generates an archiving folder 114, 116, 118 and an archiving list in a client machine 102, 104, 106 when storing an email, the archiving module may launch a replication to the server 100 in order to create the same list in the global archiving list of the server 100. Thus, the server 100 may also store each descriptive property relating to the archived email. When each client machine 102, 104, 106 archives emails, therefore, the server 100 may have a global list with sub-lists comprising local archiving lists of client machines 102, 104 and 106, for example. In addition, each time a client machine 102, 104, 106 archives an email, the server 100 may inform other client machines 102, 104, 106 in order to update their local archiving list.
As shown in
To inform the server 100 of such update, the client machine 102 may replicate the reporting log on the server 100 in a step 306. Then, the server 100 may replicate the reporting log and update the global list. When the server 100 replicates the reporting log from client machine 102, the server 100 may update the replication of the local list from client machine 102 in the global list. The server 100 may then create a temporary reporting log only available on the server 100. The temporary reporting log may only contain the second and third descriptive properties of the second email archived in client machine 102.
As soon as a replication of the reporting log is available on the server 100, the server 100 may automatically replicate the reporting log in all client machines 104, 106 other than the original client machine 102 in a step 308. This local replication of the reporting log on each client machine 104, 106 other than the client machine 102 may update local archiving lists of each client machine 104, 106. As soon as the replication is done on all other client machines 104, 106, the server 100 may remove the temporary reporting log in a step 310. Thus, the whole global archiving list may not be replicated, and only the relevant part of the global archiving list, i.e. the reporting log, may be transmitted to other client machines 104, 106.
In operation, a user may only need to read the local archiving list on the current client machine 102 to retrieve an email stored on any machine 102, 104, 106 in communication with the server 100. As the local archiving list of each client machine 102, 104, 106 may comprise replication of the local archiving lists of other client machines 102, 104, 106, the user may be able to exactly determine the location of the searched email, i.e. on the current client machine 102 of the user, or on another remote client machine 104, 106 of that user.
In order to facilitate access to emails stored on distant client machines 104, 106, the method may include additional steps to consolidate emails which refer to the same criteria, such as the same object, the same recipient or the same sender at a same location. Thus, at a defined period, which could be each month, each half-year or each year, for example, an automatic process may gather and consolidate all emails according to a predetermined consolidation profile.
In one embodiment, for example, the predetermined profile may indicate that all emails relating to the same recipient may be consolidated every month at a specific date in a particular client machine 102, referred to as the main client machine 102. Therefore, each month a replication may occur from the other client machines 104, 106 storing emails matching the criteria of the consolidation profile to the main client machine 102. As soon as all emails are replicated in the specific location or folder 114 of the main client machine 102, the replicated emails may be deleted from their original locations in the other client machines 104, 106. Thus, when a user searches for a specific email having the criteria defined in the consolidation profile, the user may search for the email from a single physical location on one client machine 102. The search is therefore more convenient than searching on different client machines 104, 106.
An embodiment may enable a client machine 102 to be informed of the content of different archives located remotely from that client machine 102. The location and the above-mentioned descriptive properties may not be specifically defined and may vary according to the preferences of a user. In an embodiment, the server 100 may be able to direct the user to the exact location of an archived email.
Embodiments of the invention have been described with reference to an email archiving tool. Other embodiments, however, may equally relate to other media, such as voice, video or any other type of information-carrying media which may need to be accessed and searched within an archive.
Embodiments may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment containing both hardware and software elements. An embodiment that is implemented in software may include, but is not limited to, firmware, resident software, microcode, etc.
Furthermore, embodiments may take the form of a computer program product accessible from a computer-usable or computer-readable medium providing program code for use by or in connection with a computer or any instruction execution system. For the purposes of this description, a computer-usable or computer readable medium may include any apparatus that may contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device.
The medium may be an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, (or apparatus or device) or a propagation medium. Examples of a computer-readable medium include a semiconductor or solid state memory, magnetic tape, a removable computer diskette, a random access memory (RAM), a read-only memory (ROM), a rigid magnetic disk and an optical disk. Current examples of optical disks include compact disk-read only memory (CD-ROM), compact disk-read/write (CD-R/W) and digital video disk (DVD).
A data processing system suitable for storing and/or executing program code may include at least one processor coupled directly or indirectly to memory elements through a system bus. The memory elements may include local memory employed during actual execution of the program code, bulk storage, and cache memories which provide temporary storage of at least some program code in order to reduce the number of times code must be retrieved from bulk storage during execution.
Input/output or I/O devices (including but not limited to keyboards, displays, pointing devices, etc.) can be coupled to the system either directly or through intervening I/O controllers.
Network adapters may also be coupled to the system to enable the data processing system to become coupled to other data processing systems or remote printers or storage devices through intervening private or public networks. Modems, cable modems and Ethernet cards are just a few of the currently available types of network adapters.
This disclosure has been presented for purposes of illustration and description but is not intended to be exhaustive or limiting. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments were chosen and described in order to explain principles and practical application, and to enable others of ordinary skill in the art to understand the disclosure for various embodiments with various modifications as are suited to the particular use contemplated.
