Hi all!
After installing new storage device how is more convenient to redirect
BACKUP from old pool to new, but not simultaneously, moving nodes by
turns. All options and schedules for nodes writed on server.

I think, it's need new policy domain, in backup copy group used new
pool, and nodes and schedules moved to this policy domain when needed.

Other ideas?

Other question (may be offtopic): is here anybody from Russia? :)
