Hi Del!
I think our SQL guys will go for the second solution. We use a
third-party scheduling tool (Control-M) and failing backups will create
a problem report.
I will forward your suggestion to them.
Again, thank you very much for your reply!
Kindest regards,

I don't think you need an external tool.
The two ways I can think of are just to run the backup on both nodes,
knowing that the backup will fail on the secondary node and succeed on
the primary node.
Or... in the script, you can use an "osql" command to query the database
state and execute the backup only if the database is online.

Thanks,

Del
