The present invention relates generally to the field of data storage, and more particularly to generating information samples during a backup operation to archival media.
Advances in information technology (IT) enable individuals, organizations, enterprises, and agencies to access and process ever-increasing volumes of stored information. Not all data is utilized within a short period of time of its generation. Historical electronic data, some of which is unstructured data, may need to be stored for weeks, months, or even years between usages. In addition, various regulatory and compliance requirements dictate that data is stored for extended periods of time. Hard disk drives (HDDs) and flash-memory drives are high-performance data storage devices but are not cost effective for long-term storage within an enterprise or cloud computing environment. Magnetic tapes within a tape storage system or a tape library are solutions for data storage of large sets of data and long-term data storage within an information lifecycle management process. Magnetic tape storage systems are a cost-effective solution and that can also be utilized for archival data storage and data storage for the purpose of disaster recovery.
According to an aspect of the present invention, there is a method, computer program product, and/or computer system for generating preview information related to data migrated to archival storage media. In an embodiment, the method includes at least one computer processor identifying data designated for archival. The method further includes at least one computer processor identifying a set of preferences associated with generating a set of preview data corresponding to the data designated for archival. The method further includes at least one computer processor determining metadata related to the data designated for archival based on the identified set of preferences. The method further includes at least one computer processor archiving the data designated for archival. The method further includes at least one computer processor responding to archiving the data designated for archival by determining information associated with archiving the designated data. The method further includes at least one computer processors generating a set of preview data corresponding to the archived designated data based, at least in part, on the determined metadata and the information associated with archiving the designated data.
Embodiments of the present invention recognize that in response to performing data migrations from active storage of a computing system to an archival storage system, descriptive information related to the data to archive is not included in the archival process. Whereas, basic information (e.g., metadata) related to a file, such as file name creation date, file size, and archival date can be readily associated with a storage volume or archival media ID that stores the archived data. Embodiments of the present invention recognize that when a user subsequently wants to re-access data of interest that was archived, the original user or another user may not know particular instance or version of the data of interest that is to be restored and accessed. In some cases, the user initiates a request to recall archival media, and subsequently one or more files (i.e., data) from the archival media are restored to a primary storage system before the user can determine whether the restored files include the data of interest to the user.
Embodiments of the present invention also recognize that retrieving archival media and restoring data from archival storage media to primary storage can be time consuming; for example, greater than 10 minutes. Lengthy data restoration durations are common and can be associated with: selecting archival storage media that potentially stores the data of interest for a user, physically moving archival media within a storage library, loading (e.g., mounting) the archival media within a reading device, and restoring some or all of the data stored on the archival media to a primary storage system for review by the user. If the wrong storage media ID was selected, then the data restoration process is repeated with another archival volume until the user finds the data of interest that the user is seeking.
Embodiments of the present invention provide a solution to reduce the duration (e.g., time) associated with a user identifying the instance of archived data that is the data of interest to the user. Embodiments of the present invention generate and aggregate preview information and metadata corresponding to data to archive during the process of migrating the data from primary storage to one or more archival storage systems. Various embodiments of the present invention are incorporated within data management systems and can customize generating additional information and/or obtaining “samples” of data during the data migration and archival processes. The additional information and/or sample data is respectively associated with the metadata of the data to archive and an ID corresponding to the archival media that stores the archived data. As referred to herein, archival storage media include magnetic tape storage, optical media storage (e.g., compact disks, laser disks, digital versatile disks, etc.), and another other bulk storage devices or media utilized for archival storage of data and information.
Some embodiments of the present invention enable a user to specify and/or configure the preview data that is determined and/or generated during a data archive process. The preview data corresponds to samples of data and other information associated with the data being archived. Preview data can be viewed during a subsequent search for data of interest to the user, thereby avoiding the need to locate archival storage media and restore archived data to verify that the selected archived data is the data of interest to the user. Other embodiments of the present invention allow a user to review a plurality of preview data to identify the instance of archived data of interest to the user and dynamically restore data of interest to the user. Embodiments of the present invention can distribute differing sets of preview data among differing systems and devices to improve accessibility and security. In addition, based on security and access controls, different portions of the preview information may be displayed based on user/group ID, user device, and/or user location.
Embodiments of the present invention improve the access time to restore the data of interest to the user. Some archival storage media, such as magnetic tape cartridges are “write once, read many” media that stores data based on sequential appends. A magnetic tape cartridge may store a plurality of data, potentially of differing users, as a series of serially appended (e.g., written) sections along the media of the magnetic tape cartridge. In some cases, specific information, such as metadata or header information related to a particular instance of archived data cannot be read until the respective section of data along the magnetic tape media is found and accessed.
A further embodiment of the present invention can utilize physical position information, corresponding to an appended section, within preview data to determine the position along the magnetic storage media (e.g., tape) where a particular instance of data was written. By utilizing physical location information within the preview data information, embodiments of the present invention can use capabilities of an archival storage system to fast-forward the archival storage media enabling faster access to archived data of interest for a user.
The descriptions of the various scenarios, instances, and examples related to the present invention have been presented for purposes of illustration but are not intended to be exhaustive or limited to the embodiments disclosed.
The present invention will now be described in detail with reference to the Figures.

In addition to the audio and visual interactions, UI 146 may receive input in response to a user of user device 140 utilizing natural language, such as written words or spoken words, that user device 140 identifies as information and/or commands.
In step 202, preview data generation program 200 identifies data within primary storage designated for archival storage. In one embodiment, preview data generation program 200 identifies data within primary storage 120 designated for archival storage based on one or more ILM dictates utilized by data management system 111. In another embodiment, preview data generation program 200 identifies data designated for archival storage based on information received from data management system 121 executing within an instance of primary storage 120, such as a user account approaching a storage capacity quota, or primary storage 120 requires additional free storage capacity to process a scheduled workload.
In another embodiment, preview data generation program 200 identifies data designated for archival storage to an instance of archival storage 130 based on information received from user device 140. Preview data generation program 200 may receive information via data management system 111 that a user of user device 140 indicates to archive data of primary storage 120. In one example, preview data generation program 200 receives data archival dictates manually input via UI 146, such as archiving a completed project or a library of back-level code. In another example, preview data generation program 200 receives data archival dictates generated by a script or other function executing within user device 140.
In step 204, preview data generation program 200 identifies a set of sampling preferences. In one embodiment, preview data generation program 200 identifies a set of sampling preferences from within sampling preferences 112. In some embodiments, preview data generation program 200 identifies a set of sampling preferences that are respectively associated with a user, a team, a project, an enterprise, etc. In another embodiment, preview data generation program 200 can receive additional sampling preference information, one or more modifications to sampling preference information, and/or a dictated set of sampling preferences via UI 146 of user device 140.
In step 206, preview data generation program 200 determines metadata related to the data for archival storage. In an embodiment, preview data generation program 200 determines metadata (discussed above) related to the data designated for archival storage based on transmitting a copy of the identified set of sampling preferences to data management system 121 executing on the instance of primary storage 120 that includes the data designated to archive. In response, preview data generation program 200 obtains, from database management system 121, the metadata related to the transmitted set of sampling preferences. In another embodiment, preview data generation program 200 obtains metadata related to the data designated for archival storage from an instance of data management system 111 that manages networked computing environment 100.
In step 208, preview data generation program 200 generates preview data. In an embodiment, preview data generation program 200 generates preview data based on combining information from two or more sources, such as the metadata determined by data management system 121 of primary storage 120 and other data/information determined by data management system 131 of archival storage 130 corresponding to the data being archived. For example, preview data generation program 200 generates a set of preview data based on including additional information from within preview information 134 that corresponds to the data being archived, such as an archival media ID, a location along the archival media where the data is stored, data compression information, etc., with metadata associated with the data to archive. In various embodiments, preview data generation program 200 can dynamically present the set of preview data to a user via UI 146 for approval and/or modification.
In step 210, preview data generation program 200 updates a preview dataset. In various embodiments, preview data generation program 200 enables a user of user device 140 to verify (e.g., add, delete, modify the metadata and/or archival information) the generated set of preview data that corresponds to the data being archived prior to including the set of preview data within a preview dataset, such as preview datasets 114. In some embodiments, preview data generation program 200 further updates a set of preview data, prior to inclusion within a preview data set, to include other information (e.g., one or more information samples), such as comments, a code snippet, a text excerpt, etc., input by a user via UI 146.
In various embodiments, in response to updating (e.g., finalizing) a set of preview data that corresponds to data that is archived, preview data generation program 200 stores the finalized preview dataset to preview datasets 114. In addition, in one scenario preview data generation program 200 updates preview dataset 144 of user device 140 to include the set of preview data related to the data is archived (e.g., the current data archival process). In another scenario, preview data generation program 200 updates preview dataset 144 of user device 140 to include a subset of the preview information included within preview datasets 114 based on sampling preferences and security constraints related to the data being archived. In other embodiments, if one or more preview dataset utilizes a formatting structure that includes RBL information, then preview data generation program 200 updates a preview dataset to includes modifications to the RBL information based on the included set of preview data.
In step 302, preview data review program 300 presents preview data related to archived data to a user. A user may refer to an individual or a member of a group, a project, a team, etc. Preview data review program 300 presents a set of preview data related to archived data utilizing UI 146. Preview data (i.e., information) includes one or more elements of information previously discussed above. In one embodiment, preview data review program 300 presents a set of preview data related to archived data based on one or more system preferences or information respectively associated with a user within user preferences 112. For example, preview data review program 300 may present preview data corresponding to archived data in stages, such as a general selection of information or information based on a criteria or an element of metadata. Subsequently, preview data review program 300 receives first user selection. In response, preview data review program 300 displays addition information, such as sample data, or a larger set of metadata information. A user utilizes UI 146 to identify (e.g., indicate) a selection of archived data to restore from among the preview data presented to the user.
In some embodiments, preview data review program 300 restricts presentation of elements of preview information related to archived data based on security dictates, such as a security clearance assigned to a user and/or a security level associated with an element of the preview information. In an example, preview data review program 300 may not present preview information related to archived data, such as a project name, team members associated with the archived data, snippets of program code, etc., based on a security level respectively assigned to a member (i.e., user) of a team. In another embodiment, preview data review program 300 presents the user preview data from one or more other sources identified during step 305.
In decision step 304, preview data review program 300 determines whether a selection of archived data is identified. In an embodiment, preview data review program 300 determines that a selection of archived data is identified to restore based on one or more user actions inputted via UI 146 of user device 140.
Responsive to determining that a selection of archive data is identified (Yes branch, decision step 304), preview data review program 300 restores the selected archived data (step 306).
In step 306, preview data review program 300 restores the selected archived data. In addition, preview data review program 300 may present the user via UI 146 one or more fields, list of systems, and/or mapped drives that enables the user to dictate the location that receives the data that is restored. In one embodiment, preview data review program 300 interfaces with data management system 131 included within the instance of archival storage 130 to restore the archived data selected by the user based on an ID, serial number, volume number, etc., corresponding to the instance of archival media 135 identified within the preview data related to the data selected to restore.
In a some embodiments, if preview data review program 300 determines that the preview dataset selected by the user also includes information corresponding to a position within the archival storage media where the selected data is stored, then preview data review program 300 can utilize data management system 131 of archival storage 130 to access and restore the selected data more quickly. For example, based on a location within the preview data corresponding to the data selected to restore, preview data review program 300 utilizes data management system 131 to instruct archival storage 130 load the instance of archival media 135 that store the selected data and fast-forward to the location along the media that includes the data selected to restore.
Referring to decision step 304, responsive to determining that a selection of archived data is not identified (No branch, decision step 304), preview data review program 300 identifies other information to preview (step 305).
In step 305, preview data review program 300 identifies other data to preview. In one embodiment, if preview dataset 144 (e.g., user defined primary search location) of user device 140 did not include the preview data related to the data of interest to the user, then preview data review program 300 identifies one or more sources of preview data for presentation to the user. For example, preview data review program 300 can identify preview dataset 114 of system 101 or another information source (not shown) identified within user preferences 112 related to the user. Subsequently, preview data review program 300 presents the other identified data for preview the user in step 302. In another embodiment, preview data review program 300 can identify other information to preview based on a user accessing, via UI 146, one or more preview datasets as another entity, such as logging-in under a group ID or a project name that include the user as a member.
