Preventing Rsync From Saving To A Local Drive

  • 772

I have a shell script on my Ubuntu 10.04 Server that runs every night and uses rsync to backup files to an external share mounted to the /media/backups folder.

The problem is, sometimes the drive isn't mounted, or the destination server is offline. When this happens, my server will happily save to a folder called /media/backups on the local filesystem, quickly filling up all available disk space.

How do you prevent rsync from writing to a folder unless that folder is a mountpoint? I just can't seem to find an answer to this on my own.

  1. With the drive unmounted, create a folder in that location and set it's permissions to 000, then mount the device over the existing folder.

    You can add this to your shell script before rsync runs:

    if ! mount | grep -q '/media/backups'; then
    echo "/media/backups not mounted"
    exit 1
fi
