what is "Default-Application-Backup" ?

NBU 7.5.0.5

whenever i create a backup policy, this "Default-Application-Backup" (with type "Application Backup") is always there. so i have to remove it because i have my own schedules.

what is it and why it gets created all the time?

    If that appears then your policy tyoe is one that requires it - such as a SQL backup

    That type of backup generally uses a script to run (a bch file for SQL)

    When your schedule runs it activates what is in effect a user backup on the client which then runs its script and that script uses the default aplication backup schedule to actually run

    Without it the backup will not run / work

    Note that the job also takes its retention period from the default application schedule and not your schedule (unless you are using SLPs)

    Normal file system backups do not have this tyoe of schedule

    Hope this helps

    thanks.

    In support of Mark's excellent explanation -  you may want to read up about Default-Application-Backup in the manual for the Database Agent that you are using.

    You need to bear in mind that the Automatic schedule will merely kick off the backup.
    Default-Application-Backup needs to have an open window during which these 'user type' backups will be allowed. The default is 24x7.
    Also note that the retention level in Automatic schedule is NOT applied to the actual backup - the retention level assigned to Default-Application-Backup determines retention levels.

    You can find links to all NBU manuals in 'Handy NBU Links' in my signature.
