Hi Emil,

if you choose a second hard drive maybe you want to take a look at 
rsnapshot. It doesn't do compression, but it can also save you a lot of 
space if you want to keep several backups (keeping data for several days 
on a daily backup basis for example). rsnapshot uses hardlinks so that 
files that didn't change aren't saved again but every backup looks like 
a full backup.

Example:

452G	/backup/daily.0/
18G	/backup/daily.1/
534M	/backup/daily.2/
534M	/backup/daily.3/
532M	/backup/daily.4/
446M	/backup/daily.5/
444M	/backup/daily.6/
471G	total

daily.0 is a full backup from today. daily.1 contains changed files from 
yesterday, daily.2 the files from the day before yesterday, and so on. 
So I can go back 7 days without having to backup 450GB each day.

So you don't have to clean up your backup by hand but still there is 
some time to notice that some files gone lost on your machine.

Bye.
