Flexible Hyper-V Backup Utility

Many thanks to everyone who has donated, sent me messages about bugs and suggestions for improvements. Your continued feedback is greatly appreciated!

This is a big update with many substantial changes to the code. I have tested it extensively but if a bug has slipped through please do not hesitate to contact me or open an issue on github.

Update Summary

  • The code has been refactored in many places and now uses functions for a lot of core operations which help greatly in maintaining it.
  • Several improvements have been made. Some small, some large.
  • Several new features have been added including a “low disk space” mode. In this mode previous backups are removed before new ones are made. There is more risk of data loss involved with this but this is now a choice you can make for yourself.

Please see the complete release notes down below for all the details.

2023-01-09: Version 23.01.09

  • Added script update checker - shows if an update is available in the log and console.
  • Added VM restore instructions to
  • Added “low disk space” mode. -LowDisk switch deletes previous backup files and folders before backup for systems with low disk space. Default behaviour only removes backups after a successful backup has occurred.
  • Added webhook option to send log file to. For Teams, Slack, Discord integration.
  • Lot’s of refactored code using functions. Simpler, easier to manage. Long overdue.
  • Fixed bug that started VMs that were shutdown.
  • Changed “VM not running” from an error state to an informational state.
  • Changed “Backup Success” to a success state (green text in console).
  • Changed -NoPerms so that VMs are now saved instead of shutdown (safer, faster, does not require Hyper-V integrations)
