We're planning a forklift upgrade of our NAS and were going to use a utility like
Robocopy to move the files over. However we'd like to preserve Windows' "Previous Versions" shadow copies. Any way to do this? Will it happen automatically? I can't find any information about Shadow Copies with Robocopy one way or another.
Edit with clarification:
Both NAS devices are EMC, although we were not planning on using the EMC upgrade tool. (Maybe we should reconsider that decision, but that's another question.)
The shares are CIFS/SMB and are accessed by Windows domain users. End users can access previous versions of files in Windows Explorer by selecting a file and going to "Properties" -> "Previous Versions". So somehow Windows is aware of the alternate versions.
My understanding was that previous version of the file was stored in something like a NTFS resource stream, which it why I think of it as basically file metadata. But maybe that's not right, or not how EMC does it. I don't know what filesystem EMC uses under the SMB covers. But if Windows can access the old file versions over SMB, why can't Robocopy?
