[Cialug] Backups with rsync

[Jonathan Bailey]

I want to do incremental backups since they take less disk space in the 
end (full backups every Sunday for example). I'd then like to rsync 
those backups to another server. This is what I'm using for incremental 
backups now - it's not perfect, but I'm lookign for better.

 rsync -av --exclude-from=/root/rs.exclude 
--compare-dest=/backup/backup-$WEK/ /home/ 
/backup/backup-$WEK-$DATESTAMP/ > /backup/backup-$WEK-$DATESTAMP.log
