Would you have any suggestions to help me resolve the error, "DPM encountered an error while performing an operation for \\?\Volume(....)\Windows\winsxs\ onThe system cannot find the path specified." while performing a Consistency Check?

I performed the following troubleshooting steps, however they all failed:

1. Re-ran the Consistency Check

2. Re-ran Create Recovery Point with Synchronization

3. Excluded the Windows\Winsxs directory

4. Excluded the entire Windows directory

Your help is very much appreciated.  Thank you in advance.

Note: Syncs and Recovery Points have been working for this C volume for several months.

Hello,

I have seen a similar error in conjunction with antivirus software. It was a different directory, but it turns out our AV (sophos endpoint protection) was blocking access to it.

If you have an AV running, you could try a clean uninstall and see if the backup works again.
