Object documentation Backup ID Locate the document in its SAP Library structure

The database system automatically gives each backup a backup ID to allow them to be identified. This ID uniquely identifies the backups done since the creation of the database instance. If external backup tools are used for the backup, the backup is given an external backup ID.

The backup ID consists of the type of backup (complete or incremental data backup or log backup) and a sequential number.

Full and incremental data backups are numbered sequentially together. Log backups are numbered in a separate sequence.

After the backup, the backup ID is written to the log dbm.knl. You can display all the contents of this file in the backup history.

In a restore the label is shown first and must be confirmed before the operation can start.

Note

If the backup medium is a tape or a cassette, you should write the backup ID on the sticker of the tape or cassette at the end of the backup.

Formal Description of the Backup IDs
