Actually this bug is quite simple to fix. The problem is that the backup
and restore both do them in the same order instead of inverting the order on
restore.
Current Code:
compress -> encrypt -> decompress -> decrypt
It should be:
compress -> encrypt -> decrypt -> decompress
I can change the restore order so that existing backups will become readable
and new backups will work whether created by the old software or the new.
I'll commit the fix once I've finished testing it.

This sounds like compression should be automatically disabled when
encrypton is enabled. Should be useless anyway as encrypted data should
no longer be compressible.
