When data is backed up or exported using a backup tool from another provider, each backup or data stream is given an external backup ID. If you created a backup using a group of parallel backup media, every part of this backup has its own external backup ID.
The Database Manager writes the external backup ID to the dbm.ebf log file and to the backup history. When restoring, choose the relevant backup from the backup IDs in the log.
The Loader writes the external backup ID to the log file of the Loader and to the Loader-related system tables. The external backup ID is required when importing data and restoring the database instance to request the required backup or data stream.
