Abstract

A system and method of managing stored data in a storage management system. The storage management system includes a storage manager, a media agent connected to the storage manager, and a primary volume connected to the media agent. Multiple snapshots are taken of the primary volume. The snapshots are indexed by associating respective information with the snapshot. The indexed snapshots are copied to a recovery volume. In this way, browsing features are enabled for the user. The user may view the snapshots in a hierarchical format, and may even view snapshot data in association with the corresponding application. The resultant recovery volume may be used to replace a primary volume.

Claims

1. A method of managing stored data in a storage management system, the storage management system including a storage manager, a media agent configured to communicate with the storage manager, and a primary volume configured to communicate with the media agent, the method comprising:

obtaining a first snapshot of the primary volume in accordance with a predefined policy,

wherein the policy comprises one or more parameters for creating a corresponding quick recovery volume, and

wherein the quick recovery volume includes information about at least one application that created data in the primary volume;

indexing the first snapshot by associating respective information with the snapshot;

obtaining a second snapshot in accordance with the predefined policy;

causing to be displayed a user interface,

wherein the user interface comprises levels of available snapshots and quick recovery volumes;

receiving from a user a selection of a displayed level; and

recovering portions of data at the selected level and any level below the selected level.

2. The method of claim 1, wherein the displayed user interface comprises multiple hierarchical levels of available snapshots and quick recovery volumes.

3. The method of claim 1, further comprising:

causing to be displayed the first snapshot to a user, wherein displaying the first snapshot includes displaying information associated with an application that created data tracked by the first snapshot, wherein the displayed first snapshot includes a date of creation of the first snapshot, a persistence of the snapshot, or a location of the snapshot.

4. The method of claim 1, wherein the causing to be displayed comprises:

causing to be displayed the first snapshot via an application that created the data of the primary volume.

5. The method of claim 1, further comprising:

presenting one or more files created by at least one application that created data comprising the primary volume;

receiving a selection from a user to restore one file selected from multiple files;

suspending access to the quick recovery volume;

restoring the selected file via the quick recovery volume; and

reinstating access to the quick recovery volume.

6. The method of claim 1, further comprising:

creating a third snapshot of the primary volume of data, wherein the third snapshot only tracks changes to the primary volume of data after the first snapshot was taken; and

selecting the third snapshot as the source of data changed after the first snapshot was taken to copy to the quick recovery volume.

7. A system of managing stored data in a storage management system, the system comprising:

a storage manager;

a media agent configured to communicate with the storage manager;

a primary volume configured to communicate with the media agent;

means for taking a first snapshot of the primary volume in accordance with a predefined policy,

wherein the policy comprises one or more parameters for creating a corresponding quick recovery volume, and

wherein the quick recovery volume includes information about at least one application that created data in the primary volume;

means for indexing the first snapshot by associating respective information with the snapshot;

means for taking a second snapshot in accordance with the predefined policy;

means for causing to be displayed a user interface comprising levels of available snapshots and quick recovery volumes;

means for receiving from a user a selection of a displayed level; and

means for recovering portions of data at the selected level and any level below the selected level.

8. The system of claim 7, wherein the displayed user interface comprises multiple hierarchical levels of available snapshots and quick recovery volumes.

9. At least one non-transitory tangible computer-readable storage medium carrying instructions, which when implemented by at least one data processing device, manages stored data in a storage management system, wherein the storage management system includes a storage manager, a media agent configured to communicate with the storage manager, and a primary volume configured to communicate with the media agent, comprising:

taking a first snapshot of the primary volume in accordance with a predefined policy, the policy comprising one or more parameters for creating a corresponding quick recovery volume, and wherein the quick recovery volume includes information about at least one application that created data in the primary volume;

indexing the first snapshot by associating respective information with the snapshot;

taking a second snapshot, in accordance with the predefined policy;

displaying a user interface comprising levels of available snapshots and quick recovery volumes;

receiving from a user a selection of a displayed level; and

recovering portions of data at the selected level and any level below the selected level.

10. The computer-readable storage medium of claim 9, wherein the displayed user interface comprises multiple hierarchical levels of available snapshots and quick recovery volumes.

11. At least one non-transitory tangible computer-readable storage medium carrying instructions, which when implemented by at least one data processing device, manages stored data in a storage management system, wherein the storage management system includes a media agent and a primary volume configured to communicate with the media agent, comprising:

obtaining a first snapshot of the primary volume in accordance with a predefined policy,

wherein the policy comprises one or more parameters for creating a corresponding quick recovery volume, and

wherein the quick recovery volume includes information about at least one application that created data in the primary volume;

indexing the first snapshot by associating respective information with the snapshot;

obtaining a second snapshot in accordance with the predefined policy;

causing to be displayed a user interface,

wherein the user interface comprises levels of available snapshots and quick recovery volumes;

receiving from a user a selection of a displayed level; and

recovering portions of data at the selected level and any level below the selected level.

12. The computer-readable storage medium of claim 11, wherein the displayed user interface comprises multiple hierarchical levels of available snapshots and quick recovery volumes.

13. The computer-readable storage medium of claim 11, further comprising:

causing to be displayed the first snapshot to a user, wherein displaying the first snapshot includes displaying information associated with an application that created data tracked by the first snapshot, wherein the displayed first snapshot includes a date of creation of the first snapshot, a persistence of the snapshot, or a location of the snapshot.

14. The computer-readable storage medium of claim 11, wherein the causing to be displayed comprises:

causing to be displayed the first snapshot via an application that created the data of the primary volume.

15. The computer-readable storage medium of claim 11, further comprising:

presenting one or more files created by at least one application that created data comprising the primary volume;

receiving a selection from a user to restore one file selected from multiple files;

suspending access to the quick recovery volume;

restoring the selected file via the quick recovery volume; and

reinstating access to the quick recovery volume.

16. The computer-readable storage medium of claim 11, further comprising:

creating a third snapshot of the primary volume of data, wherein the third snapshot only tracks changes to the primary volume of data after the first snapshot was taken; and

selecting the third snapshot as the source of data changed after the first snapshot was taken to copy to the quick recovery volume.
