script for rsnapshot calls, but mount the backup device, before this si done and unmount afterwards. Thisway, we might consume less power, because this is only done oncy a day (or week!!)

RSNAPSHOT=/usr/bin/rsnapshot

DEVICE=/dev/disk/by-label/Backup
MOUNTPNT=/media/Backup

#mount

if [ ! $? -eq 0 ] ; then
        echo mount $DEVICE $MOUNTPNT
        mount $DEVICE $MOUNTPNT
        if [ $? -eq 0 ] ; then
                mounted=1
        fi

#do snapshot with $1 as interval
echo $RSNAPSHOT $1
$RSNAPSHOT $1

#umount
if [ $mounted -eq 1 ] ; then
        echo umount $DEVICE
        umount $DEVICE
