Subject: dd to /dev/tape Advantages ?
Date: Fri, 11 Jan 2002 02:23:57 -0500
For backups,
I understand the disadvantages and simplicity of using tar.
I also like using dump now that I understand it.
I was wondering if anyone was using dd to make tape backups.
What are the advantages/ disadvantages.
i.e.
Using dd to write to Tape (raw dump)
-----------------------------------------
mt -f /dev/nst0 rewind
dd if=/proc/kcore of=/dev/nst0 bs=20480 count=10
mt -f /dev/nst0 status
mt -f /dev/nst0 rewind
dd if=/dev/nst0 of=/tmp/rwtest.dat bs=20480
ls -l /tmp/rwtest.dat

To backup harddrive filesystems, it would make restoration's a bit tricky in
that the partition sizes would have to be the exactly the same. I've never
tried it, but running fsck on a filesystem where the size of the dd written
to the disk was different than the partition, would be interesting.
