Dumping /dev/sd0c or /dev/dsk/c0t3d0s2 will only dump the first filesystem
of the disk and then only if the partition containing that filesystem
starts in cylinder 0. So this will usually give you a dump tape with only
/dev/sd0a or /dev/dsk/c0t3d0s0.
This doesn't work either;
trying to dump two filesystems with one dump command:
ufsdump 0f /dev/null / /ufs1
ufsdump 0f /dev/null /dev/dsk/c0t3d0s0 /dev/dsk/c0t1d0s0
will also result in only one filesystem dumped
(believe me, I just tried this to make sure)
Please remember that dump/ufsdump back up a *filesystem*, not a
partition. It can therefor only dump *one* filesystem, or
part thereof, at a time.
Dumping multiple filesystems is only possible by using multiple

method may go unnoticed until the backups are needed.
