If you get this Error after a update Installation just delete the following Reg Key and the Exchange Backup works:

Open Regedit
Navigate to [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\VSS\Providers\]
Make a backup of that key.
Delete the key {f782463b-33bb-4043-ad8d-60b728d26a6c}
Open the Windows Services management console (services.msc)
Restart the ‘Microsoft Software Shadow Copy Provider’ service
Try backup

Hello tobias lowescher,

Thank you for posting your suggestion in our forum.

(!) You do every change on MS Windows registry on your own risk.

Only if you get the information from official Acronis support, these steps are verified and do not conflict with Microsoft Windows Registry settings.

In your case it might be enough to edit the existing task to the default of ‘Software – System Provider’ in volume shadow copy options and to ensure, that the Acronis VSS Provider Service is set to ‘manual’ and not ‘deactivated’.

If you run into any issue, regarding this or other errors using Acronis Backup & Recovery 11.5 please contact Acronis support. You can find information that is more detailed about your support options in our Customer Handbook.

Please let me know if you have additional questions.

Thank you.

Been having this problem on all the boxes we upgraded from 10 to 11.5, could see it was a VSS issue, but hadn't got any further. Was about to try reboots and re registoring the VSS dlls....

This seems to have solved it so far, will report back after the backup finishes !

This didn't seem to solve the issue, for me. I get two sets of warnings.
First one.

Then this one seconds later

i have set the plan to use acronis VSS and have removed the reg key (as per the link) reboot of units. This is happpening to three mail servers. Two of which got a upgrade to 11.5 from 10 and the other had a unistall, cleanup tool, reboot, then install of 11.5

Any ideas ?

Just cause i know it's annoying when u find someone having the say issue and the posts stop.

I HAVE FIXED IT.

I belive this was because the 3 exchange boxes were also DCs. I did the regedit, changed the plan to use "system provider VSS" (so windows Volume shadow copy) AND changed the plan to use the domain admin account to excute (tho you should really create a seprate account with the same rights and run it under there)

I hope this helps any one in the furture (or myself when i forget what the fix was)
