    -a      Backup all VMs.
    -b      Specify output directory
    -c      Export compressed backups. Set to either true or false. Defaults to true.
    -C      Specify config file. Defaults to /etc/xenserver-backup.cfg
    -d      Dry run.
    -e      Space separated list of VMs that should not be backed up.
    -l      Enable/disable logging with 'true' or 'false'.
    -m      Mount command to run previous to running the backup.
    -u      Specify VMs to back up via uuid.
