Installation Back Up
When upgrading, it is important to have an off line system backup. If anything goes wrong, the installation can be restored from this backup.
The system administrator should know how to back up and restore from the backup, either the complete system or just the Ingres parts of the installation.
After backup has been done:
• Verify the backup as readable, regardless of whether the backup was to tape or disk.
• Make no changes to the Ingres Installation.
• Store the backup in a secure location.
