Hello Chris,
yes we thought about cron but our Novell Consulting Team is afraid to get handling issues by our Novell Operating Admins. So they are not happy with a cron solution.
But we got a hint from one of our Senior Employee to solve the issue with cascading jobs:
First job is a dummy job ( i.e. backup SYS:) with a pre command to mount the Volume1.
Second job is the job to backup Volume1 with a pre command which mounts volume2 ...
Not very elegant but it should work and i guess there is currently no other way.
Thanks and greetings
Michael
