that script is than the rsync script? Pretty much the same features.
Simple is my middle name. I think I'll use this script.
Now is the following okay? Will it work as is?
Step 1. wait for Oct 31st, since this cron script will run the next
morning
2. on Oct 31st, login as root
3. create the file backup.sh, as below, in /etc/cron.daily/
4. set perms of backup.sh to 755
5. md /backups/last-full
6. logout and let cron do its thing
