A data backup saves the contents of the data volumes, and the database parameter values needed for restores.
For the SAP DB database system, we differentiate between the following types of data backup:
You can perform complete and incremental data backups in the operational mode ONLINE or ADMIN. When doing so, you can back up to a group of parallel backup media. Data backups are always consistent in themselves.
Use the Database Manager or, in SAP systems, the DBA Planning Calendar to perform the backups.
Database Manager GUI: SAP DB 7.4, Section Backup Processes
Database Manager CLI: SAP DB 7.4, Commands for Backing Up and Archiving
Database Administration in CCMS: SAP DB OLTP, DBA Planning Calendar
To restore a database instance, you may also need log backups in addition to a data backup.
