Use

You can save the data to a Structure linksingle backup medium. If the capacity of the backup medium selected is too small for the backup, succeeding media have to be used, meaning that when one backup medium is full, it must be automatically or manually replaced by an empty one on the request of the Database Manager GUI:

 

Note

If possible, it is always preferable to save to a group of parallel backup media rather than backing up to a single medium plus succeeding media. Parallel backup of this kind is not however possible for log backups.

Prerequisites

Only one backup device is available.

You have defined the backup medium to be used for the backup. If you want to perform a backup using an automatic tape loader (Backups to Automatic Tape Loader), or with the help of external backup tools(Backups with External Backup Tools) , then you must state this specifically when defining the media.

Note

Under normal circumstances, you should not backup Structure linkdatabase instances if they are in ONLINE mode.
You can also backup database instances in ADMIN mode, but only in exceptional circumstances. However, if you backup in cold mode, you no longer have the choice between backing up for recovery (a complete backup of data without Structure linkcheckpoint) and backing up for migration (a complete backup of data with checkpoint) because there is no real guarantee that the database instance was shutdown in the correct way.

Procedure

  1. Choose Instance ® Backup and the required backup type:
    ® Complete (complete backup)
    ® Incremental     (incremental backup)
    ® Log     (interactive log backup)
    ®     AutoLog (automatic log backup)

    The list of the media defined for the selected backup type appears in the output display.
    If no media have been defined yet, you must now define them (see     Creating a Single Backup Medium). Select the medium to be used for the backup.
  2. Check the details of the medium. Change them if required (Changing Backup Media).
  3. In the menu bar at the top of the screen, choose Backup and the required backup type.
    For     Structure linkdata backups, choose whether the backup is for the purposes of
    Recovery (data backup without checkpoint), that is, to recover the database instance after an error, or
    Migration (data backup with checkpoint), that is, to migrate the database instance.
  4. If you have selected a data backup or interactive log backup, now choose Backup ® Start. The backup action now starts.
    If the capacity of the backup medium specified is not large enough for the backup and you are not using an automatic tape loader, the Database Manager GUI asks you to specify and insert a new medium as soon as the previous medium has been filled (see     Backups to Manually Changed Media).
    Once the backup procedure has been successfully completed, you see the message     Backup completed.

    If you want to activated the automatic log backup, choose Backup ® AutoLog on.
