Every backup that is created on a
backup medium using an external backup tool has a unique external backup ID. This ID is generated by the DBM Server or the backup tool during the backup. If a backup was created using a media group, every part of this backup has its own external backup ID.The external backup ID is written to logs
dbm.knl (backup history) and dbm.ebf during backup.The external backup ID is used during a restore to request the desired backup. The external backup ID is displayed before the restore operation, and can be corrected if necessary. To do this, the
Database Manager transfers the external backup ID to the DBM Server as a command parameter, and the DBM server forwards this to the external backup tool.
