RoboCopy and Network Shares
If the source of a /MOVE /MOV or target of a /MIR /PURGE operation is a MIG protected volume on a network share then all delete operations are blocked. This is because RoboCopy 'Rules' can only be applied if the Windows session that's opening the files is the same Windows session that's running RoboCopy. In the case of a network share, the remote computer is opening the files and will block all delete operations.
