Soda Posted November 19, 2017 Report Share Posted November 19, 2017 Hi, I get the following 2 errors Writer "NPS VSS Writer" backup failed, error -1101 (file/directory not found). Component "NPS Database" backup failed, error -1101 (file/directory not found). It appears to happens when the snapshot is being saved Everything else seems to work as normal. I do not have any errors/warnings in windows event viewer > Windows Logs > System This started after I recycled my Backup Set. However this is the first such backup after windows updated itself to 1709 and also retrospect updated itself to 12.6.1.101 so really it could be anything! Any ideas on what it is and how to move forward? Thanks Quote Link to comment Share on other sites More sharing options...
Soda Posted November 19, 2017 Author Report Share Posted November 19, 2017 I have done something incredibly stupid I found that there was a pending update which windows had downloaded and queued. After a restart the problem went away. So as you see it's actually Windows 10 whose fault it was. Quote Link to comment Share on other sites More sharing options...
Scillonian Posted November 19, 2017 Report Share Posted November 19, 2017 In your case a restart fixed it but if it doesn't when I have had the NPS VSS Writer and NPS Database errors in the past on Windows 10 Clients I have fixed it by adding an empty (zero byte) file named "ias.xml" in the "C:\Windows\System32\ias\" folder on the affected Client.
