robocopy /copyall - ERROR

Thanks for the response Stephen; unfortunately (I'm pretty sure) I do need the auditing information and the file permissions need to be exact. If DFS notices any differences in the permissions it will treat the data like it's pre-existing, will ignore it, and will copy the entire data set over the WAN (which is exactly what I'm trying to avoid).

Yep, I was running all commands from an elevated PowerShell window, didn't seem to help.

UPDATE: After taking ownership of the 'DATA' share, I was able to get the command to execute with the /copyall switch, but the NAS is changing the permissions on the files and when I compare the file hashes they don't match.

Its starting to look like I bought a ReadyNAS that won't support iSCSI or any sort of features that would be useful for creating backups with unmodified permissions... Unless I install the ssh and apt plugins, and start hacking away.

If anyone has has been able to successfully pre-stage DFS data on a ReadyNAS Duo V2 any advice/pointers would be greatly appreciated.
