A system indexes a first backup file, created for a data object when a first time period expired, in a first level of a data structure. The system indexes a second backup file, created for the data object when a second time period expired, in a second level of the data structure, the second time period being shorter than the first time period. The system receives a request to restore the data object to a specified time. The system enables restoration of the data object by identifying a first indexed backup file associated with the specified time in the first level of the data structure, by identifying a part of the second level of the data structure corresponding to the first indexed backup file, and by identifying a second indexed backup file associated with the specified time in the part of the second level of the data structure.

Multi-level indexing of backup files

A backup storage for managing backups of clients includes persistent storage and a backup analyzer. The persistent storage includes the backups, protection policies, and an early deletion schedule. The backup analyzer obtains a request to analyze a protection policy of the protection policies; in response to obtaining the request: obtains backup data information associated with the protection policy; makes a determination, based on the backup data information and the protection policy, that a portion of the backups associated with the protection policies overprotect a client of the clients associated with the protection policy; and modifies the early deletion schedule based on the determination to obtain a modified early deletion schedule.
