Volume Shadow Copy Service error (multiple times)

[amcfarla]

I installed DrivePool 64bit on 4/4/2015, since then my application log is just filled with 'Volume Shadow Copy Service error: Unexpected error DeviceIoControl'.  Today alone there are easily more than 100 log entries for this.  Why am I getting so many Volume Shadow Copy Service errors?  This is the last one I received:

O: drive is my drivepool drive that the application created.

You opened a ticket for this as well, and I have answered there, first.

 

 

But basically, these are fine.

StableBit DrivePool doesn't support VSS (Volume Shadow Copy Service), and  therefore cannot create snapshots.

You've already confirmed that the system protection option is disabled for the pool, as well.

Make sure you're not using Windows Backup or similar to back up the pool drive as well. 

 

 

These are normal, as the VSS will attempt to take snapshots of all drives regardless of the configuration. Worst case, you can disable the VSS service completely, but that will break Previous Versions, System Restore, and Windows backup.
