US Patent 11435933 Using any-pit backups for retroactive backup compliance and hardening

Retroactive backup compliance. A data stream from a production site is stored in secondary storage associated with a data protection system. In response to an event such as a regulation change or a service level agreement change, backups are generated retroactively from the stored data stream. Backups are generated to correspond to times in the past. Backups can also be replaced, deleted, or generated ad-hoc. Further, the retroactively generated backups are generated to be consistent.
