I have never heard of any "sometimes" RAID setup. I don't think that
is possible. I would say just do incremental backups every night.
There are many tools, rsync being the most commonly used. If you use
LVM, you could also try taking LVM snapshots.

I personally use rsnapshot, a wrapper around rsync, to back up every
night. So far it has saved me countless times.
