We do incremental backups using cpio.  The script follows:


#!/bin/sh
# backwk.bat - incremental backup of system files
#
cd /
find . -mtime -1 -print | egrep -v "^(./usr/spool/news/)" | cpio -ovC1000 >/dev/rmt0

...this script finds and backs up all files created/modified "today" or
"yesterday".  Everything is backed up except news  :-) .
Look up grep or egrep if you want to exclude other directories.

P.S.  Our full filesystem backups are the same as above, except that
'-mtime -1' is removed, and the cd / is changed to /usr, /u, etc.
For the root filesystem, we 'cd /' and egrep -v /usr, /u, etc., so they
won't be backed up twice.

cpio knows how to tell you to put in a 2nd cartridge, so large backups
work, too   ;-)
