I'm using a robocopy script with the switches /COPYALL and /B on my Windows 7 Home Premium PC to backup files to a NAS and I'm getting the error message:

ERROR 1314 (0x00000522) Copying NTFS Security to Destination File (file-location/name) required privilege is not held by the client.

I think it is something to do with account privileges in Windows 7 Home Premium - I read somewhere you need to add the account to the Backup Operators group - but that is for the Server OS.

How can I overcome this problem without upgrading to Windows 7 Pro?

Note: The other Win 7 computer on the network which is Pro does not have this issue.

  • Download the Windows Server 2003 Resource Kit Tools. Extract the rktools.exe downloaded file using 7-Zip. Then extract rktools.msi. Among all the files there's one called ntrights.exe. To grant backup privileges to a specific user, run this command from an elevated command prompt: ntrights.exe -u "some_user_name" +r SeBackupPrivilege

Reset to default

this option should solve the problem and will copy the attributes required.
/COPY:DATSO

Here is more description on this

/COPY:copyflag[s] :: what to COPY for files (default is /COPY:DAT).

(copyflags : D=Data, A=Attributes, T=Timestamps).

(S=Security=NTFS ACLs, O=Owner info, U=aUditing info).

  • It's the 'U' option which causes the failure

  • For me, DATSO worked but DATSOU failed. I concluded that 'U' was the problem
