You can execute backups of data or log entries interactively with the Database Manager GUI or with the Backup Wizard. Depending on the technical requirements, the following backup procedures are possible:
· Backing Up to a Single Backup Medium
· Backing Up to a Group of Parallel Backup Media
If the capacity of the selected backup medium is sufficient for the total quantity of data or log entries that needs to be backed up, then the database administrator does not need to intervene during the backup process.
If the capacity of the selected backup medium is not sufficient for the backup, succeeding media must be used, meaning that when one backup medium is full, it must be automatically or manually replaced by an empty medium:
· Backups to Automatic Tape Loader
· Backups with Manually Changed Media (Succeeding Medium)
The Backup Wizard requests additional backup media when a medium has been completely filled but the backup has not yet been completed. To allow it to do this, the media size must be stated when defining the medium, or the tape device must detect the end of the tape.
You also have the option of using an external backup tool.
· Saving with External Backup Tools
There is an automatic backup function for backing up the log entries:
· Activating and Deactivating the Automatic Log Backup
