Appl. No.:

13/333400

Inventors:

Surya K. Ghatty - Rochester MN, US
James P. Smith - Redwood City CA, US
Peter B. Symonds - Portola Valley CA, US
William R. Yonker - Rochester MN, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 7/00

US Classification:

707695

Abstract:

Provided are computer program product, system, and method for assessing a backup image comprising a backup of a source computer system to recover to a target computer system. A point-in-time backup image is selected from a plurality of backup images taken of an image on the source computer system, wherein the selected backup is to be applied to the target computer system. A determination is made from a plurality of retention policies applicable to files included in the source computer system a most restrictive retention policy. A determination is made as to whether the selected backup image satisfies the most restrictive retention policy. A retention status of the backup image is set based on whether the determined version of the selected backup satisfies the most restrictive retention policy. The retention status is presented for use in determining whether to use the selected backup image.

Appl. No.:

10/764069

Inventors:

Edward Barton - Pleasanton CA, US
Avishai Hochberg - San Jose CA, US
James Smith - Redwood City CA, US
Peter Symonds - Morgan Hill CA, US

International Classification:

G06F012/00

US Classification:

707204000

Abstract:

One aspect of the invention is a method for ensuring consistency of a group, which for example, includes receiving a first list that identifies objects in the group, and gathering for at least one attribute, the value of the attribute for each object in the first list. The first list, and the attribute values gathered in the gathering operation, are stored to create a first snapshot. This example also includes receiving a second list that identifies objects that are in the group after at least part of a task is performed, and the value after at least part of the task is performed of the at least one attribute for each object identified in the second list. The second list and the received attribute values are stored to create a second snapshot, which is compared with the first snapshot.

International Classification:

G06F 12/16

US Classification:

707204000

Abstract:

One aspect of the invention is a method for backing up files, which for example, includes, scanning at least one directory; creating a first list comprising all files at a time tin the scanned at least one directory; saving values of a plurality of attributes, corresponding at the time t, with each file in the first group of files, to create a first snapshot; backing up the files in the first group of files; scanning the at least one directory after backing up the files in the first group of files; creating a second list comprising all files at a time tin the scanned at least one directory; saving values of the plurality of attributes, corresponding at the time t, with each file in the second group of files, to create a second snapshot; and comparing the first snapshot with the second snapshot.

US Classification:

707649, 707E17005

Abstract:

A point-in-time backup image is selected from a plurality of backup images of an image on a source computer system to be applied to the target computer system. A first assessment value is associated with an extent to which critical files and recovery metadata are included in the selected backup based on an include list of critical files and recovery metadata to include in the backup. A second assessment value comprises a backup status of the critical files and the recovery metadata. A third assessment value is indicative of an extent to which the selected backup satisfies requirements of a retention policy. A fourth assessment value is indicative of an extent to which computational resources and device drivers in the target computer system are compatible. An overall assessment value for the selected backup image is determined based on the determined first, second, third, and fourth assessment values.

Abstract:

A system correlates application information from within a virtual guest to an entity managing off-host data protection. During a data protection operation, the system exploits the virtual hierarchy to centralize the configuration and management of operating system credentials of numerous virtual guests. For each virtual guest, the system uses the credential to collect a single Globally Unique Identifier (GUID) previously generated and stored in-guest by any data protection agent. The system stores the collected GUID as a custom property in the context of the virtual hierarchy. The system also exploits the virtual hierarchy custom properties to determine if GUIDs are copies due to virtual guest replication. The system ensures GUID's uniqueness by requesting regeneration of the GUID by in-guest data protection agents. Using GUIDs that are unique across the virtual hierarchy, from the entity managing off-host data protection, the system can correlate application data of multiple in-guest data protection agents.
