CrashPlan and Volume Shadow Copy Service error

A day after I thought I fixed the problem, the VSS error reoccurred

I contacted CrashPlan as the error occurred while it was running. It seems that there is a conflict with VSS when CrashPlan tries to backup open files. At the end it works, but I get all these errors logged in the event log.

Their suggestion was to disable the “Backup Open FIles” option in CrashPlan. I will continue investigating.

Hello Oscar.

This error would point to an issue with VSS on your machine. We do have an article that outlines what VSS is and how CrashPlan uses it located here:

If you want to prevent CrashPlan from using VSS, you can turn off the “Backup Open FIles” option in CrashPlan by going to Settings > Backup > Click on (Configure…) next to Advanced Backup Settings and uncheck the Backup Open Files box.

If you have any other questions feel free to let me know.

I find this error on the event log every time CrashPlan Runs:
