In Win8.1Pro 64 bit used the command line:
Robocopy V: F: \ backup /MIR / R:0
The copied directories now take most of the space on an external Lacie HD F: . All the files and directories seem to be hidden though, neither command line DOS evel nor Windows 8.1 sees anything on the Lacie.
The background , V: is the project file server of an architecture office and F: is a USB external HD rotated weekly and stored elsewhere for backup. I used to do this with SyncToy on Win XP Pro from 2007 onward but just switched to Win 8.1 and noticed that SyncToy is not supported . Found Robocopy after some googling . Took me some trial end error to get the above command line running, had to figure out where to put empty spaces in the command line and where not to . Would really appreciate if someone knowledgeable could help me write a command line that mirrors the content of V: to F:\backup without hiding it . Further , do I need a second version of the command line to do subsequent runs in a way that only copies new and changed files and folders to F: ? A full run takes in excess of seven hours.
