Try running a scheduler in each cluster group.  That way the backups
will happen even if the groups are not on their "normal" nodes.

We did a test and failed the drives from one cluster node to the other
and
the same results, the next scheduled backup only backed up the base
directories with no errors.

Previous day 1.4 million files scanned 21,000+ backed up, day the drives
were failed only 10 files scanned 1 backed up and no error messages.

Scheduler service is not defined in the cluster service, Because the
backup
schedules for these systems would not complete in 12 hours if both
devices
were backed up from one of the two cluster nodes.

Only top level directories are backed up on f: and g:?  How do you know
this?

What schedmode are you using?  Is your scheduler service defined in
cluster
administrator?

What if you do a failover without doing the patches part, does the same
thing happen?
