Under normal operation, the backup-method property performs a full backup using the OpenEdge PROBKUP utility when you set its value to full-offline.

This backup is performed in two steps. The first step is a full backup, which is performed before AI is enabled for the database. The second step is an incremental backup, which is performed after AI is enabled and after the role of the database is changed.

Online failover transition changes the behavior of the backup-method property during failover transition when the property is set to full-offline. In this instance, the property will behave as follows:

  • The mark backup method will be honored, but the rfutil db-name -C mark backedup command will not be performed. The database will still be marked as backed up, and AI extents will not be used when recovering from a disaster. If transition fails when the mark backup-method is configured, a rebase is required because there is no backup.
  • If a full-offline backup is specified and restart-after-transition is set to 1, the designated backup method will not be honored and the backup will execute as a full-online backup. This applies to both the recovery backup prior to failover transition and backups performed during transition.
  • If a full-offline backup is specified and restart-after-transition is set to 0, the designated backup method will be honored and the backup will execute as a full-offline backup.
