Thanks, that cleared it up for me. I am not familiar with dump, does it work with ext4 systems? The deb package says ext2.

Genuine question, what is the difference?

[ between backups and copies ] The point of this comparison is that if you wanted a copy, the first case gave you that; but if you wanted a backup, it didn't. Not really. But if you wanted a backup, the second case gave you that; but not a copy. Not exactly. (Dump's output is a single file that contains all of the files it backed up -- similar to tar, but quite a different format and with different metadata.) The larger point is that rsync makes copies, dump makes backups (and tar makes archives, hence its name). Each tool has its advantages and disadvantages, and sometimes one can be substituted for another is certain preconditions are met -- or if the task is some hybrid of copies/backups/archives. Folks have also built systems on top of them (notably using rsync in recent years) that provide the sort of incremental backup capability that dump's had since forever. The trick is figuring out which problem you're actually trying to solve, and having done that, selecting the right tool and using it the right way. ---rsk ___________________________________________________________________________ Philadelphia Linux Users Group -- http://www.phillylinux.org Announcements - http://lists.phillylinux.org/mailman/listinfo/plug-announce General Discussion -- http://lists.phillylinux.org/mailman/listinfo/plug
