rdiff-backup vs. backuppc


Genecks

Recommended Posts

So, I was talking to someone recently, and they said that rdiff-backup is basically the same thing as BackupPC. However, I didn't believe that, as I was with the understanding that BackupPC differently does one major thing:

 

1) Makes a pool so that no file ever, despite ever being moved in the folder tree, needs to be copied over again.

 

This is correct, yes?

 

And rdiff-backup does not do this, right?

 

I'm using rdiff-backup at the moment. I backed things up. Afterward, I renamed a directory with files in it. From there, I backed things up again. It would appear that rdiff-backup had decided to backup all of the files again along with the folder they are in.

 

BackupPC is different in this regard, as it will checksum the pool, notice the files are there, adjust and create a symlinked foldertree, right? rdiff-backup is not doing this?
