Oracle backs up your application and data to create a snapshot while performing daily maintenance of your environment.
Every day, during the operational maintenance of the environment, Oracle backs up the content of the environment to create a maintenance snapshot of existing artifacts and data. See Overview of the Maintenance Snapshot in Getting Started with Oracle Enterprise Performance Management Cloud for Administrators for a detailed description of the maintenance snapshot.
Additionally, Service Administrators can create full backup snapshots of the environment or incremental backup snapshots of artifacts at any time. See Backing up Artifacts and Application.
Generally, a snapshot is compatible with the previous and next updates of an environment. For example, a snapshot from the 19.09 update of Oracle Enterprise Performance Management Cloud will be compatible with 19.08 and 19.10 environments, and can be imported into these environments.Account Reconciliation only: Account Reconciliation does not support the migration of snapshots from the latest service update to an earlier service update (for example, when moving snapshots between test and production environments during the window when the test environment is upgraded before the production environment.)
Snapshot and File Retention Policy
Files and snapshots that you create or upload to an environment are deleted after 60 days. The daily maintenance process monitors the environment and automatically removes snapshots older than 60 days. If the total size of all snapshots exceeds 150 GB, it deletes snapshots from the last 60 days, 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.
Data Management process log files are retained for seven days only. Oracle recommends that you regularly download the files you want to keep to a local machine.
How do I Find the Modified Date?
Use the Shapshots tab in Migration to identify the size and the date and time when available snapshots were last modified.
The last modified time is displayed based on the time zone specified in User Preferences. If it is not set, the last modified time is displayed based on the browser time zone..
To view snapshot size and last modified time:
- Access Migration (see Accessing Migration for Lifecycle Management).
- Click Snapshots.
