Block size used will have a significant influence especially if you are 
backing up mostly small files.

Then there's the space taken up by filesystem structures (inodes etc) which 
can vary.  Compare the characteristics of ext3 and xfs if you want to figure 
out what might cause this in your case (e.g. 
http://en.wikipedia.org/wiki/Comparison_of_file_systems).

Note you may wish to reconsider using xfs: it does not support block 
journalling, only metadata (see the above link, and also 
http://wiki.dirvish.org/?ReiserFSConsideredHarmeful - ReiserFS in Linux now 
supports block journalling according to the Wikipedia article, but the 
article's main point can probably be applied to XFS).  Depends on how 
important the data is I suppose... ;-)

Cheers,
Eric
