The System Writer Is Not Found in the Backup
Some users may not know what system writer functionality is. The Shadow Copy System Writer is used by the cryptographic services. To enumerate and replace system files when the signature of a system file is different from the signature stored in the security catalog database, you’ll need the System Writer.
A common issue the System Writer is not found in the backup is annoying many users. Both in Windows Server 2012 and Windows Server 2008, sometimes you may receive the error message if you try to make a backup.
There are 2 common reasons that can cause the issue:
