Managing Maintenance Snapshots

Maintenance snapshots are created primarily to restore your environment in the case of a catastrophic failure.

All files and snapshots that you create or upload to an Oracle Enterprise Performance Management Cloud environment are deleted from the environment after 60 days. The daily maintenance process monitors environments and automatically removes snapshots older than 60 days. If the total size of all remaining snapshots exceeds 150 GB, it deletes snapshots created in the last 60 days but older than 48 hours, oldest first, until the total size of snapshots is less than 150 GB. The daily maintenance snapshot, irrespective of its size, is always retained. If your maintenance snapshot is larger than 150 GB, then only the maintenance snapshot is retained; all other snapshots are deleted.

The daily snapshot is then archived with the retention policy described in Archival, Retention, and Retrieval of Daily Snapshots.

Exceptions

• Narrative Reporting retains only the current snapshot (EPRCS_Backup.tar.gz) of the environment.

  Thus, the 150 GB limit is not applicable to Narrative Reporting, but retention period for files and uploaded artifacts is enforced.

• Data Management process log files are retained for seven days only.
