i pass along next following. do not recall where came from before i
added to my tape script collection and made minor 'save space' edits.
***
thad phetteplace, claims, for a 'level' back up :::
#!/bin/sh
# backups.sh - simple backup script, by Thad Phetteplace
# put in /usr/local/bin as 'backups.sh', permission = 700 (-rwx------).
# manually back up, usage 'backups.sh [dumplevel]'
# script takes one parameter, dump level.
# if no dump level provided, set zero.
# level zero (full) dump, rewinds and ejects tape when done.
if [ $1 ]; then
level=$1
else # dump level not provided, set zero
level="0"

/sbin/dump $level -u -f dev/nrft0 /home
/sbin/dump $level -u -f dev/nrft0 /var
/sbin/dump $level -u -f dev/nrft0 /usr

if [ $level = "0" ]; then
/bin/mt -f /dev/ntft0 rewind # /bin/st if SCSI tape

easy, no special programs.

cd to top directory of path to back up when doing
write. this way, when you restore, you may restore
files were ever you wish, as '/' is never implied.
'grep -iv "\./proc"' eliminates '/proc' from path '/'

why cpio?
cpio is available on all systems, as is tar.
cpio will span multiple tapes, as will tar.
cpio will skip bad data and tell you, tar may not.
