XenServer Virtual Machine Backup script

Recently busy with the virtual machine, what data need to be backed up, even if the virtual machine is no exception, the following is my own written backup script to use according to the actual situation,:

First do an NFS server, this server requires a large disk, and then need to back up the virtual server host on the shared directory

Then you can implement a script to make a scheduled task do a backup
