It's worth noting that Linus Torvalds believes the program to be
terminally broken:

He writes:

This is possibly true if used on live filesystems. However if you either take your filesystem offline before dumping it, or just remount it read-only for the duration of the dump there is no problem. With the latest Fedora release the filesystems are by default LVM volumes so the easy solution is to create a snapshot and dump that.


I still find dump/restore to be a very easy to use backup tool.

I should also note that since reporting this in bugzilla I've been contacted by the dump/restore maintainer with a temporary workaround to get our backups going again. He's also provided a test patch to enable the selinux attributes to be saved and restored and this functionality should make it into a future release.
