Well, yeah, that could make things more challenging. Of course, then you don't really know if you got a good copy at all, right? So snapshotting a mirror or breaking and then re-syncing would probably be a good approach there.
All of this presumes, of course, that one is worried about integrity, which should be pretty simple in this day and age, but I have to admit that I spend more time than I should arguing with my spinning media :-(
Sometimes I do a backup of the offline system, but that means that I have to boot from something else, then do the backup. This is an operation that takes hours. After that, I do more frequent backups (incremental, with rsync), while online. Yes, of course, some files will be in transient state, but all work files will be in their saved states. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
