Summary. More than 2:1 favor 1:1. If you do compress, compressing the
entire backup is bogus, it should be done file by file, and preferably
by the backup device.

The interesting news is backup verification. I typically look at the
file sizes and go, "yeah, it ran." Prob'ly not good enough.

Also, one can argue in favor of FEC for archival storage, so if you lose
a track or set of blocks you can still recover. I backup to RAID.
