Yeah, I see now that it is hard links. So this is deffenitly how it's suppose to work then obviously. In the past, I have always seen backuppc not use hard links at all. That is, it copies all the files that have changed, and then just leaves them there. If I do a `du` on one of the incremental directories, it would only show up the amount of space that the incrementals actually used. Any ideas why it would have done that?

These are Hardlinks to the pool or cpool directory. Look in the Readme 
for more details.
