How to disable DB2 - Archived log backup?

Hi,

DB2 Archived_Logs_Backup - Used for backing up only archived logs. This type of backup specification can be saved, but not started or scheduled. It is used every time the User Exit program starts the backup of archived logs.

Question is:
How to temporarily disable DB2 - Archived log backup, without Shutting down Cell Manager?
Let's say, for example, because of: "omnidbutil -purge -filenames -force"
which Requires exclusive access to the IDB.

Thanks & Regards,
Tom
