This script will suspend your VM temporary and make the backups of the VM's where it won't consumes space to make the VM's backup.

If you have sufficient space and want to make the VM's backup without suspending the VM's you can use the below script.

Code starts 

#!/bin/bash

if [ ! -d "/mnt/vmshare" ]

then

        mkdir /mnt/vmshare;

fi

mount -t cifs //sharename or IP address/VMBACKUP /mnt/vmshare -o username=username,password=password,domain=domain_name;

if [ `echo $?` -eq 0 ]

then

        cd /mnt/vmshare;

        uidsnap=$(xe vm-snapshot uuid=db99ad46-30ae-93d4-0699-9b60f84527f0 new-namelabel=vmtest-$date);

        c="dc01.domain.com_$(date +%d-%B-%Y)".xva;

        xe template-param-set is-a-template=false ha-always-run=false uuid=$uids                                                                                        nap;

        xe vm-export vm=$uidsnap filename=/mnt/vmshare/$c compress=true;

        cd /root

        umount /mnt/vmshare;

        xe vm-uninstall uuid=$uidsnap force=true;

fi

Code Ends.

Here to make the backup of the VM's first we need to find out the UUID of the VM.

# Xe vm-list              is the command to find out the list of VM's running on Xenserver.

Copy the UUID of the desired VM you want to make the backup and use the UUID in the script.

You can also use this script to make an automatic schedule.

#crontab -l

List the current schedules

#crontab -e

Edit the scheduler to add your scripts in automatic backups.
