VSS Shadow copies none existent

Hello,

I am trying to get one of our servers to back up. This is proving difficult as I can't figure out what is wrong with my Shadow Copies so I can't really do much. I have tried adding more storage (only about 30GB but it was a 60GB disk so its a x1.5 incresess.) I have set the Shadow copies to unlimited.

I have done everything in hearing from Quest

VSS Troubleshooting Guide – Failed VSS Writers (4034380)

It is also a Virtual Machine on HyperV. The other VMs running on the same server are fine. I would like to avoid rebuilding it as it hasn't backed up since 26/03/2024

It says to go to Mircosoft but they never come back to me so I was hoping someone here would have a similar issue and be able to help?

Thanks

George

    Hi George,

    Thanks for your post. Can I know if you have met any error message during the failed backup process. For example, A Volume Shadow Copy Service Operation failed. Detailed Error: The volume shadow copy operation failed with error 0x800423F4. View the event log for more information.

    Also, please go to the Application log and see if there is any evidence with Source: Microsoft-Windows-Backup

    Here is the troubleshooting guide for the specific logs and events. Just for your reference and hope it is helpful.
