My previous backup solution actually uses tar, but there's two problems
that I have with it:

1. My backup file, even when compressed with .bz2, exceeds 2 GB by a
little. The backup machine has an older kernel that doesn't support >2 GB
files and upgrading it is not an option because this is a dedicated

2. tar archives are a pain to work with if I just want to go in and find
one specific file that I need to recover; it takes a long time to extract
a file.

Giving the situation some more thought, it might not be hard to be able to
use rsync to preserve file ownership without having root access.  It would
be just a matter of getting a "ls -lR" of the data, and having some
program that can parse that to recover the original file ownership if

Has anyone already done something like this by any chance?
