Recording audio with LC

I decided that RAID arrays aren't really useful as a "backup" after my last
disaster (Raid rebuilds on a 500 gig drive takes longer than 8 hours), I
hate the fact that files are accessible from a single drive after a crash of
one, and have gone to a mirror strategy with regular backups done several
times a day.

The archive master is fed from a collection drive first to save wear and
tear on the archive master. So at times there are three copies of the latest
transfers existing. Then I use FolderSynchroniser or Carbon Copy Cloner to
maintain sync between versions. This is multi-gig sized video and audio
files.

RAID is great for faster access time, but for archive, it scares me.
Definitely good to separate the working from the archive.
