Using any-pit backups for retroactive backup compliance and hardening

1. A method for performing a data protection operation, the method comprising:

receiving a data stream from a production site at a data protection system configured to perform the data protection operation, wherein the data stream includes a journal of writes performed at the production site;

generating backups from the data stream, the backups including a first backup;

persisting the data stream at a storage by the data protection system; and

generating a backup based on an event for a point in time in the past that is earlier than a time associated with the first backup, wherein the backup is generated by synthesizing the persisted data stream, wherein synthesizing the persisted data stream includes including, in the backup being generated, at least the writes in the journal from a backup in the backups that is associated with a backup created at a time earlier than the point in time up to the point in time in the past, wherein writes in the journal after the point in time in the past are not included in the backup being generated.

2. The method of claim 1 , further comprising deduplicating the data stream.

3. The method of claim 1 , further comprising receiving a new policy, wherein the event is the new policy and where the backup is generated to comply with the new policy.

4. The method of claim 1 , further comprising identifying data in the data stream that is inconsistent, wherein the data is associated with a time region, and deleting a backup associated with the time region.

5. The method of claim 4 , further comprising generating a new backup from a point in time that is later than the time region or generating the new backup from a point in time that is earlier than the time region, wherein the new backup is consistent.

6. The method of claim 1 , wherein the event is a change in regulations associated with backups generated by the data protection system, a change in a cadence of the backups, a change in a retention period of the backups, detection go inconsistent data in the journal.

7. The method of claim 1 , further comprising hardening the backup such that the backup is guaranteed consistent.

8. The method of claim 1 , further comprising virtually synthesizing the backup.

9. The method of claim 1 , receiving a policy that is associated with backups generated by the data protection system, wherein the policy changes a schedule associated with the backups.

10. The method of claim 1 , further comprising applying a heuristic to backups associated with the data protection system in response to the event, wherein the heuristic is one of deleting a specific backup, replacing the specific backup with another backup that is associated with a different time than the specific backup.

11. A non-transitory storage medium having stored therein instructions that are executable by one or more hardware processors to perform operations comprising:

receiving a data stream from a production site at a data protection system configured to perform the data protection operation, wherein the data stream includes a journal of writes performed at the production site;

generating backups from the data stream, the backups including a first backup;

persisting the data stream at a storage by the data protection system; and

generating a backup based on an event for a point in time in the past that is earlier than a time associated with the first backup, wherein the backup is generated by synthesizing the persisted data stream, wherein synthesizing the persisted data stream includes including, in the backup being generated, at least the writes in the journal from a backup in the backups that is associated with a backup created at a time earlier than the point in time up to the point in time in the past, wherein writes in the journal after the point in time in the past are not included in the backup being generated.

12. The non-transitory storage medium of claim 11 , the operations further comprising deduplicating the data stream.

13. The non-transitory storage medium of claim 11 , the operations further comprising receiving a new policy, wherein the event is the new policy and where the backup is generated to comply with the new policy.

14. The non-transitory storage medium of claim 11 , the operations further comprising identifying data in the data stream that is inconsistent, wherein the data is associated with a time region, and deleting a backup associated with the time region.

15. The non-transitory storage medium of claim 14 , the operations further comprising generating a new backup from a point in time that is later than the time region or generating the new backup from a point in time that is earlier than the time region, wherein the new backup is consistent.

16. The non-transitory storage medium of claim 11 , wherein the event is a change in regulations associated with backups generated by the data protection system, a change in a cadence of the backups, a change in a retention period of the backups, detection go inconsistent data in the journal.

17. The non-transitory storage medium of claim 11 , the operations further comprising hardening the backup such that the backup is guaranteed consistent.

18. The non-transitory storage medium of claim 11 , the operations further comprising virtually synthesizing the backup.

19. The non-transitory storage medium of claim 11 , the operations receiving a policy that is associated with backups generated by the data protection system, wherein the policy changes a schedule associated with the backups.

20. The non-transitory storage medium of claim 11 , the operations further comprising applying a heuristic to backups associated with the data protection system in response to the event, wherein the heuristic is one of deleting a specific backup, replacing the specific backup with another backup that is associated with a different time than the specific backup.
