rsync backups

rsync can be used as an effective backup tool:

rsync -avz --delete -e "ssh -i rsync/mirrorkey" backup@ /backup/

If there’s a lot of data and speed takes importance over security, a weaker cipher such as blowfish could be used:

"ssh -c blowfish -ax -i rsync/mirrorkey"

Be careful with the –delete flag, it will delete files on destination if they exist.
