X-Mailer: VM 6.22 under Emacs 19.34.3 Sender: owner-freebsd-bugs@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Now... I havn't exhaustively tested this, but I recently tried dumping a couple of filesystems onto a tape, and then restoring them. The restore came up with less than half the files on the origional filesystem --- and a whole pile of messages about skipping blocks on the tape and so on. I've been trying this with multiple tapes and different systems. I even added a second SCSI card (to separate the tape and disk drives). You might think that is end of story. However, when I tar'd the same partition to tape (tar -cvlf /dev/rst0 /) and then tested the tar tape (tar -dvf /dev/rst0), no errors were reported (save /dev/ttyp0 had changed owners, but that was a known thing). This has all left me rather puzzled. Is dump reliable at all?
