Hi,
My Veeam Agent for Windows backup is stuck at 0% on snapshot creation.
When I run vssadmin list providers in PowerShell, no providers are listed. It seems the default Microsoft VSS provider is missing or unregistered.
What is the proper procedure to re-register the VSS provider without corrupting existing shadow copies ?
Thanks !
+23First off what version of Windows is this on? Did you check Google?
You can use this article but with caution - Re-Registering VSS DLL Binaries in 32-bit and 64-bit Environments
+23Yep...recommend following the process Chris shared to attempt to re-register your Windows VSS as a first step, then re-attempt a backup. Let us know how it goes
+5Hi,
Update / Solved:
I am on Windows 10 Pro
An important detail I forgot to mention: everything was working fine when Acronis was installed. The Veeam issue started right after I uninstalled Acronis. It looks like the Acronis uninstaller removed or unregistered the default Microsoft VSS provider / filter drivers during cleanup.
Progress update:
Following the DLL re-registration procedure (unregistering/registering VSS DLLs in system32 and restarting vss + swprv services), vssadmin list providers is now no longer empty !
It now properly shows:
Microsoft Software Shadow Copy provider 1.0 (ID: {b5946137-7b9f-4925-af80-51abd60b20d5}).
I will now reboot the machine and re-run the Veeam Agent backup job to verify if it completes successfully. I'll.

Yeah would make sense, Acronis has its own (optional afaik) VSS provider and probably during the clean up something went screwy.
Thanks for sharing the additional details, it sounds like probably you’ve got the solution :)

Glad to hear you got it sorted
+23Glad to hear it was something simple
Why do you say I've solved it? Unfortunately, I'm still stuck. 😅

Well, you never mentioned or followed up with whether the job ran or not, so we assumed I guess it was resolved. I can unmark the answer until you get one that does solve the issue.
What is the issue now with the agent after getting VSS working?

Well, I don't understand why it's not saving, even with the solutions provided, the commands aren't working.
I'm attaching the log.

I also tried with AOMEI and it does the same thing, so the problem is with Windows.
Where could that have come from ?

No clue maybe an update? If another product has the same issue you need to get windows fixed it sounds like.

well, it’s why i wrote “probably” ;)
What’s the current situation? Just what you told made sense so figured it would work, but unclear what the current status is
It's the Acronis Cleanup Utility that needs to break or delete something, But what ?
I restored a backup from last week with Acronis still installed. It works now, so I think I'll leave it as is.

Then leave it. You need to figure out why Acronis broke Windows VSS. That is not something we can answer though, and you would need to reach out to them.

Do you think this could be an indication ?

How to uninstall Acronis True Image using Cleanup Utility
+23You need to uninstall Acronis in the most efficient way possible and to me, that is via the Add/Remove programs. Not sure what the hang-up is here as that is what is causing the problems you experienced.

If this is part of the uninstallation instructions to be completed then you need to follow it!
