Easy and cheap way to backup your running Hyper-V disks. The script is using the VSS technology to allow you to backup your disk even if the VM is in use.
The script is using an individual xml configuration to allow a flexible way of doing backups

The Chilcat ActiveX component is needed for reading the configuration, please get it here


  • The script has been tested on Windows 10 and Server 2016.

Syntax:

> cscript hvbackup.vbs

Note that the default configuration (hvbackup.xml) is getting loaded if no parameter is given

Alternative Syntax

> cscript hvbackup.vbs <optional configuration.xml>



Setup hvbackup.xml

  • Edit hvbackup.xml
psad2ipt.xml
XML Child Element XML Attribute Value

Check the amount of free disk space on the target befoe we refuse the backup operation.
