--> NAME
--> dump - filesystem backup
-->
--> SYNOPSIS
--> dump [0123456789BbhfusTdWn [argument ...]] filesystem
--> dump [0123456789BbhfusTdWn [argument ...]] directory
-->
-->
--> It *can* do it,
Not on Linux. The Linux version accepts a directory name as a
convenient shorthand, but dumps the whole filesystem containing
that directory:
bash# dump 0f /dev/null /etc
DUMP: Date of this level 0 dump: Tue Mar 23 01:17:42 1999
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/sdb1 (/) to /dev/null
DUMP: mapping (Pass I) [regular files]
DUMP: mapping (Pass II) [directories]
DUMP: estimated 2342 tape blocks on 0.06 tape(s).
DUMP: dumping (Pass III) [directories]
DUMP: dumping (Pass IV) [regular files]
DUMP: DUMP: 2276 tape blocks on 1 volumes(s)
DUMP: Closing /dev/null
DUMP: DUMP IS DONE
bash#

P.S. We've probably overstayed our welcome for backup issues using
this mailing list ... perhaps we should take further dump
discussions offline.
