Edit the client settings (Apps & Modules tab) and enter the following command in the 'backup command' field:

    save -a "ignore-all-missing-system-files=yes"

Then retry the backup.

ideally this should work, if the quotes are used correctly. Sometimes misplaced quotes are the problem.

save -a '"ignore-all-missing-system-files=yes"'

Check whether one of the writers fails as well. Run "vssadim list writers" and evaluate the result.

If the system writer has a problem, run this procedure to cure it:

  Takeown /f %windir%\winsxs\filemaps\* /a
  icacls %windir%\winsxs\filemaps\*.* /grant "NT AUTHORITY\SYSTEM:(RX)"
  icacls %windir%\winsxs\filemaps\*.* /grant "NT Service\trustedinstaller:(F)"
  icacls %windir%\winsxs\filemaps\*.* /grant BUILTIN\Users:(RX)
  net stop cryptsvc
  net start cryptsvc

  net stop nsrexecd
  net start nsrexecd

Thanks Bingo.Does it require reboot?

Not on windows 2008 and higher.

I am also facing the same issue , when i fire Disaster Recovery backup

Check the backup user is having domain permissions

and its should be the local admin of the client

also check ACL setting of the client

Check the antivirus, the issue can occur due to same also

Run backup from client level and check, using Networker user

check

vssadmin list writers

vssadmin list providers

vssadmin list shadows

vssadmin list shadowstorage

The issue is because of antivirus , i had disabled the same tested backup its working fine

hi
