If a failure occurs with the database server, media, or ON–Bar during a restore, you can restart the restore from the place that it failed. By default, the RESTARTABLE_RESTORE parameter is ON. If it is OFF, you must shut down and restart the database server before you begin the original restore. To restart a failed warm or cold restore, issue the onbar -RESTART command. All restarted restores resume where the last restore failed.
If the failure occurred during a physical restore, ON–Bar restarts the restore at the storage space and level where the failure occurred. It does not matter whether the restore was warm or cold.
If a failure occurred during a cold logical restore, ON–Bar restarts the logical restore from the most recent log checkpoint. Restartable logical restore is supported for cold restores only. However, if the failure during a warm restore caused the database server to shut down, do not restart the restore. Instead, use the archecker utility to verify the backup and start the whole restore from the beginning.
