Failed to creat volume snapshot

Hello Steve,

Thank you for your post. I will do my best to help you.

This looks like an issue with Acronis low-level drivers responsible for disk operations. I will send you a private message with a download link for the drivers and provide you with instructions for collecting low-level drivers logs that require the same file so that you can contact our Support team directly for additional investigation.

Please let me know if you have additional questions.

Thank you.

Received a similar error - unable to create snapshot. File level backup - always create a snapshot
I created this task about 3 weeks ago and ran fine. Build 12708. Am I correct in that w/o a snapshot - files in use will not get backed up??? VSS or non-VSS,MS or ACRONIS ??? THANK You

Mine started a week ago. Check your services. If Acronis VSS Providor service is running stop and disable it. I found that little tib bit on anoter thread. It seemed to fix mine.

I've yet to complete a backup without the VSS error and have tried every VSS option and suggestion in this forum. I found the system provider for Win 7 was not set to automatically start so I changed that and still no success.

Acronis support provided the updated driver package SnapAPI so that was installed and a new backup plan created after restart and still VSS errors.

If Acronis knew what was causing this there would already be a fix. I have tried multiple machines and they each encounter the VSS problem and occasionally this error stops the backup.

I hope a solution is found soon as time is being waste and deployment halted.

Hi Richard

What I would suggest checking into is ensure that the Acronis VSS and Microsoft VSS services are currently STOPPED!

Then edit your backup job and make sure you are using the System provider VSS option (this should use Microsoft VSS as the main snapshot engine.

I’ve had a few customers where VSS seemed to get in a confused state and manually stopping both Acronis and MS VSS services seemed to reset things and get backups working constantly from then on.

Hope that helps for you as well.

So far I have been able to successfully complete a backup of random files from each drive on two Windows 7 computers without VSS error.

I had to set both the Microsoft Software Shadow Copy Provider and the Volume Shadow Copy services to manual start because both are shown to be in use during the backup.

I set both the plan and default Volume Shadow Copy Service to use "Software - System Provider".

So far, about 25% for one and 40% complete for the other, no VSS or partition locking errors appear before data backup begins.

Windows 2003 R2 Server SP2

I just completed my first successful backup with v11 since installing a few weeks ago. I disabled the Acronis VSS Provider in services and changed the volume shadow copy service in the job to Software - System Provider. The job completed with warnings. So the backup worked but the SS still failed. In services the MS provider says started even after the job completes. I had to manually stopped it.

Has anyone tried disabling the MS VSC service and using the Acronis provider?

Yes I tried it using only MS VSC and using only Acronis VSS and errors were received.

I also changed the VSS method in the plan and the default settings using all variations and continued receiving errors.

Only with both services enabled and the method described above would complete without errors on two machines.

I have the same problem on a windows XP Professional 32 bit with Acronis Backup & Recovery 10 Workstation.

Can you please send me the low level Drivers as well.

Thank you!
