ADABAS supports complete and incremental data backups providing the required restore and restart functions in order to make databases operational again after power and media failures. Periodic backups are indispensable for production database environments.
To ensure round-the-clock operation, data backups (complete and incremental) can be performed in warm mode and log segments can be automatically saved as soon as they have been completed.
Data backups are done with checkpoint; i.e., they are consistent. Data backups can be performed in warm database mode. This can impair database operation.
As the low speed of the tape devices involved is a limiting factor for save and restore operations, ADABAS provides the option to save to or restore from several tape devices in parallel. Up to 32 tape devices can be used to reduce save and restore times considerably. This is not possible for save log segment.
