I have an HP computer that I have upgraded to Windows 10. I am trying to complete a backup using the system restore. Each time it fails and gives me the message that the backup did not complete correctly. I tried to defrag and do a clean up first. I also tried to back up using the Windows 10 file history backup feature. When I do this I get the error message that the backup failed due to a Volume Shadow Copy Service (VSS) err. The error occurred while trying to contact VSS writers.
Any suggestions as to what to complete the backup to an external drive and why these errors are showing up?
