This is the incremental backup script I use on my Linux box at home, a quick-and-dirty imitation of what Time Machine does. Obviously $HOME/backup is a different physical disk. Feel free to improve on this. -------- #!/bin/bash HOME= date=`date "+%Y-%m-%dT%H:%M:%S"` rsync -aP --link-dest=$HOME/backup/current /home $HOME/backup/back-$date rsync -aP --link-dest=$HOME/backup/current /etc $HOME/backup/back-$date rm $HOME/backup/current ln -s back-$date $HOME/backup/current #see if the disk is getting full FREE=`df -lk|grep sdb1|awk -F" " '{print $5}'|awk -F"%" '{print $1}'` #alert me if the backup disk is getting full. T=80 if [ "$FREE" -gt "$T" ] then df -lk| mail $myaddress -s"disk alert $T% capacity" else echo "backup disk is less than $T full" fi
