-VM_XENHOST=$(xe vm-list | grep 'Control domain on host' | awk -F ': ' '{ print $3 }')
-VM_XENUUID=$(xe vm-list params uuid=$(xe vm-list | grep -B1 $VM_XENHOST | grep uuid | awk -F ': ' '{ print $2 }') | grep resident-on | awk -F ': ' '{ print $2 }')
-</file>
-Set log path:
-<file>
-log_path="/VM_Backup/"$VM_XENHOST"/"$date".log"
-</file>
-Set the backup destination:
-<file>
-backup_dir="/VM_Backup/"$VM_XENHOST"/"
-</file>
-Ensure only running VMs are backed up:
-<file>
-backup_vms="running"

-Edit the ''vm_backup.lib'' file:
-<file>
-vi /VM_Backup/vm_backup.lib
