About Environment Backups and Snapshots
Every day, during the operational maintenance of the environment, Oracle backs up the content of the environment to create an Environment Backup and a maintenance snapshot of existing artifacts, setup data, and Data Management staging table data.
These backups then can be used to migrate content to another environment. See these topics in the Getting Started Guide for Administrators:
- Overview of Daily Backups
- Artifacts Included Only in Environment Backups
- Managing Daily Backups
- Version Compatibility
- Difference Between Environment Backup and Artifact Snapshot
- Archival, Retention, and Retrieval of Daily Backups
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.
Environment Backup and Snapshot Version Compatibility
Environment Backups and Artifact Snapshots can be restored or imported only within supported version ranges of the environment. See Version Compatibility in Getting Started Guide for Administrators for information on version compatibility.
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 on the environment. 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 or copy them to Oracle Object Storage.
About the XML Files in the Snapshot
The XML files included in Oracle Fusion Cloud Enterprise Performance Management snapshots use an Oracle defined proprietary format. This format may change to accommodate changes that occur over Cloud EPM releases. Any custom process or utility that you use should not depend on the XML format remaining unchanged across Cloud EPM releases.Manually Modifying Snapshots
Any changes you want to make to a snapshot must be made to the application before generating the snapshot. Never change the XML files in snapshots to update artifacts. If you update the XML files in the snapshots manually, the import may fail. Even if the import works, the application may perform incorrectly.
Oracle does not support manually changing the XML files in snapshots.
How do I Find the Modified Date?
Use the Snapshots 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.
