Depends what you mean by that, of course, but I am pretty sure it  
does.  At least that is what I was using it for (until I ran out of  
disk space).

It gives you independent backups using hard links to files that  
haven't changed and you can tell it to keep last N backups.

It's old now and probably doesn't support all the latest OSX features  
(ACLs) but most backup programs have their limitations.
