No - the backup will abort but NetBackup will automatically restart failed
jobs.  Your job log may show a stream start, fail, and then try 2 will pick
up the job on the new host.  Depending on exactly how you're doing your
backups and what you have for checkpoints, you may not even lose most of the
work you've done before you had the cluster transition.

I would assume, though, that you're not doing a lot of cluster
transitions...  If so, backups aren't your biggest problem :-)
