You don't need to backup the whole /. I have a file called backuplist: /etc/ /usr/local/ /root/ /var/local/ /home/ and I have a file called excludelist: /var/local/backup /var/local/unbackedup /home/dtutty/uldl /root/uldl These are both in /usr/local/lib/backup, although they should go in /etc/ but I wanted to avoid any conflicts with any package I may install that would have /etc/backup/. For completeness, here's my whole backup script. This is for my main box titan. Less complex scripts are run on other boxes. Other scrips do the rsync. Note that my /home is on a cat lvm while my system (including /var/local where the backups go) is on lvm over raid1. Doug. ----
