I have re-written the popular Citrix XenServer 5.5 Automated Live VM Backup scripts from scratch, with some big improvements:
- Separate backup configuration script – So you don’t need to touch the key execution and function scripts to configure backups.
- VDI removal – Run in addition to the standard vm-uninstall command to stop snapshotted VMs allocating all your disk space
- Logging – Enable/disable functionality with more advanced function logging and file path customisation.
- Backup VM selection – The facility to select between all, running, none and specifically set (by VM uuid) virtual machines.
- Quiesce snapshots – To take advantage of the quiesce snapshot functionality if the VM supports it.
- HA disabled – High availability is disabled on exported virtual machines to stop configuration issues when re-importing.
This is a complete re-write from scratch and as such is relatively untested other than on my systems – please provide feedback regarding any successful or problematic installations.
The latest release of the updated Citrix XenServer Backup Scripts can be downloaded from http://www.andy-burton.co.uk/files/xenserver_backup/xenserver_backup.tar.gz as a tar gzip archive.

[root@xs backup]# chmod 700 vm_backup.*
[root@xs backup]# ./vm_backup.sh
[root@xs backup]# nano vm_backup.log
Open and edit vm_backup.cfg to configure the backup.
Run vm_backup.sh to run the backup process, this script does not need to be modified.
The virtual machine backup functions are located in vm_backup.lib and do not need to be modified.
As usual, all comments, negative, neutral or positive are all very welcome.
For those that require it, I will write additional information and a more detailed installation procedure in due course.
