Feature Request: Add compression to backups

[dth202]

currently the worlds are just getting backed up via cp -r, which is okay but then can we have it tar or gunzip the world folder so it doesn't take up so much space? Doing this would allow those with less storage space to be able to have larger retention periods

This was a great idea so I made a pull request here: 3e67dad (#6)
