Actually you can do incremental tar/cpio/afio backups. Even much better than with dump (IMHO - but I don't like dump anyhow, as many people might know) Include in a script lines like: cd / find . -newer /usr/adm/LASTBACKUP.TIMESTAMP -print | \ tee /tmp/files | \ sed -f '/usr/local/adm/stopWords.backup' >> /tmp/copyTheseFiles This writes all files of the path (here /) that are newer than the file /usr/adm/LASTBACKUP.TIMESTAMP (which gets touched after a successful backup) in a file and then (this dump can't do) excludes a list of stopwords. (for example, I don't really want to backup my swapfile and (all of) spool and tmp directories.) Finally this list gets piped to afio (which is a better cpio): (cat /tmp/copyTheseFiles | \ /usr/local/bin/afio -ovuz -b126b -s150m /dev/rst0 | \ tee "/dev/"$tty ) >>& /usr/adm/backup.log Okay, this line is a rather bad hack (it is running in tcsh - I should rewrite the program for sh!!!! But no time and not the mood... ;-) ) We have joy, we have fun, we have Pacman for the sun...
