Aha.  I guess I was caught up trying to keep 100% of the benefits of compression.  In that case, I can just create parity files (for example, using Parchive, http://parchive.sourceforge.net/) and use them for recovery.

Heh.  I guess that's a bit more redundancy than I need for this stuff.... (ironically, these are backups taken from my RAID-1 setup).

Thanks.
