I use a raid 1 of two 1TB drives with BTRFS for file backup. I would have preferred to use ZFS, but BTRFS has better linux support and the main feature I wanted from ZFS: checksums on data and metadata. It's reassuring to start a BTRFS scrub and see the results come back OK without having to run hashdeep or some other SHA/MD5 utility on my files.

That said, hashdeep is still great: http://md5deep.sourceforge.net/ [sourceforge.net]
