I'm using Back In Time to back up my desktop to a flash drive.  As the 
program uses links to represent files that haven't changed (a great 
saving in both time and space) provided that the target media can 
support them, I've reformatted the drive to ext4.  Currently, I have 
about 31GB of data backed up to a 16GB drive, with about 8GB still free. 
  This may or may not be the right solution for you, but it's worked 
just fine for me.

And, in case anybody's wondering, I once deleted a folder I didn't need 
any more then restored it from the backup, just to make sure that the 
restore function worked as advertised.
