Can robocopy mirror?

Hi,

Is it possible to mirror two folders, one on a PC the other on an external HDD?

So if said person updates a file on PC, when the run the app it updates the change to the external HDD, and visa versa?

It's probably really simple, but I can't seem to do it in the GUI and I just wondered if it futile.

Thanks

The mirror switche mirrors folders with robocopy. It doesn't monitor folders though which i suspect is what you're after. You shedule robocopy.

//Edit: Ok sorry its the /MIR switch, which is the same as /E /Purge AFAIK.

quick question as I have enabled the mirror option.

however it only seems to be copying one way, not both, if that makes sense. If I make a change on machine 1 it copies to machine 2.

If I make a change on machine 2 it doesn't copy to machine 1.

i'd imagine you need to run it twice, once from source to dest, then from dest to source

worth testing before putting in real env.

That has to be done with a bat file? The GUI version a bit naff as you can only have one install?

IIRC the mirror option will delete files in the destination that are not in the source.

^ I can confirm this is correct. It's a mirror, not a sync.

not using the MIR, just using the /E option
