How about an extra hard drive?  I just picked up a 320gb for $120.  Do you 
need to be saving all this data cumulatively or can you use rsync to 
overwrite previously saved data?  Is this like a nightly backup or a 
additionaly data to large and growing project?  Usually, compression is 
more of a problem that it is worth, in my opinion.  Especially in a day 
when disk space really is cheap.
