Abstract

Subject matter related to data management is disclosed. Snapshots of a target object in a computing system may be stored, where the snapshots may correspond to multiple versions of the target object. A first indication that information in a snapshot of the snapshots is flagged for quarantine may be obtained. Based on receiving the first indication, a second indication that the information in the snapshot is prohibited from being restored during a restoration operation for the target operation may be generated. The second indication that the information in the snapshot is prohibited from being restored may be stored.

First claim

What is claimed is:

1. A method, comprising:
generating a table comprising one or more entries indicating whether information in one or more snapshots of one or more target objects in a computing system is quarantined;
storing a plurality of snapshots of a target object in the computing system, the plurality of snapshots corresponding to a plurality of versions of the target object;
obtaining a first indication that information in a snapshot of the plurality of snapshots of the target object is flagged for quarantine;
adding, based at least in part on receiving the first indication, an entry to the table, the entry comprising an indication of the target object, an indication of the snapshot, and an indication that the information in the snapshot is quarantined;
releasing, after adding the entry to the table, a first portion of the information in the snapshot from quarantine; and
updating the table to indicate a second portion of the information in the snapshot that remains quarantined.

2. The method of claim 1 , further comprising:
determining that the information in the snapshot is infected by malware; and
generating the first indication that the information in the snapshot is flagged for quarantine based at least in part on determining the information is infected by malware, wherein the first indication is obtained based at least in part on generating the first indication.

3. The method of claim 1 , wherein obtaining the first indication comprises:
receiving the first indication from a second computing system, wherein the first indication is associated with a user, and wherein the indication that the information in the snapshot is quarantined is based at least in part on the user having privileges that satisfy a threshold.

4. The method of claim 1 , further comprising:
identifying a second snapshot of the one or more snapshots that comprises the information in the snapshot; and
adding, based at least in part on identifying the second snapshot, a second entry to the table, the second entry comprising an indication that the information in the second snapshot is quarantined.

5. The method of claim 1 , further comprising:
identifying a second snapshot of the target object taken after the snapshot, the second snapshot of the target object including the information in the snapshot; and
adding, based at least in part on identifying the second snapshot of the target object, a second entry to the table, the second entry comprising an indication that the information in the second snapshot of the target object is quarantined.

6. The method of claim 5 , further comprising:
identifying a third snapshot of the target object taken after the second snapshot of the target object;
determining that the third snapshot of the target object lacks the information in the snapshot of the target object; and
adding, based at least in part on identifying the second snapshot of the target object, a third entry to the table, the third entry comprising an indication that the information in the second snapshot of the target object is permitted to be restored.

7. The method of claim 1 , further comprising:
identifying, at a second computing system, a duplicate version of the snapshot; and
adding, based at least in part on identifying the duplicate version, a second entry to the table, the second entry comprising an indication that the information in the duplicate version of the snapshot is quarantined.

8. The method of claim 1 , further comprising:
receiving a command to release the second portion of the information in the snapshot from quarantine, wherein the command is associated with a user;
releasing the second portion of the information in the snapshot from quarantine based at least in part on the user having privileges that satisfy a threshold; and
storing a third indication that the information in the snapshot is permitted to be restored based at least in part on releasing the information in the snapshot.

9. The method of claim 1 , further comprising:
identifying a second snapshot that comprises the information in the snapshot; and
adding, to the table, a second entry after the entry, the second entry comprising an indication of the second snapshot and an indication that the second snapshot is quarantined.

10. The method of claim 1 , further comprising:
releasing the second portion of the information in the snapshot from quarantine; and
adding, to the table after the entry, a second entry comprising a second indication of the snapshot and an indication that the snapshot is released from quarantine, wherein the entry remains in the table after the second entry is added to the table.

11. The method of claim 1 , wherein the entry further comprises an indication of a location of the information in the snapshot, and wherein the indication indicates that the information in the snapshot at the location is quarantined.

12. The method of claim 1 , further comprising:
identifying a second snapshot that comprises the information in the snapshot; and
adding, to the table, a second entry after the entry, the second entry comprising an indication of the second snapshot.

13. The method of claim 1 , further comprising:
releasing the information in the snapshot from quarantine; and
removing the entry from the table.

14. An apparatus, comprising:
a processor; and
a memory storing instructions that, when executed by the processor, cause the apparatus to:
generate a table comprising one or more entries indicating whether information in one or more snapshots of one or more target objects in a computing system is quarantined;
store a plurality of snapshots of a target object in the computing system, the plurality of snapshots corresponding to a plurality of versions of the target object;
obtain a first indication that information in a snapshot of the plurality of snapshots of the target object is flagged for quarantine;
add, based at least in part on receiving the first indication, an entry to the table, the entry comprising an indication of the target object, an indication of the snapshot, and an indication that the information in the snapshot is quarantined;
release, after adding the entry to the table, a first portion of the information in the snapshot from quarantine; and
update the table to indicate a second portion of the information in the snapshot that remains quarantined.

15. The apparatus of claim 14 , wherein the instructions are further executable by the processor to cause the apparatus to:
determining that the information in the snapshot is infected by malware; and
generating the first indication that the information in the snapshot is flagged for quarantine based at least in part on determining the information is infected by malware, wherein the first indication is obtained based at least in part on generating the first indication.

16. The apparatus of claim 14 , wherein the instructions are further executable by the processor to cause the apparatus to:
receiving the first indication from a second computing system, wherein the first indication is associated with a user, and wherein the indication that the information in the snapshot is quarantined is generated based at least in part on the user having privileges that satisfy a threshold.

17. A non-transitory, computer-readable medium storing code comprising instructions executable by a processor of a device to cause the device to:
generate a table comprising one or more entries indicating whether information in one or more snapshots of one or more target objects in a computing system is quaran
