Can WD Smartware backup from one PC to two units?

Maybe this is basic, but I still like to ask rather than making mistakes. I want to make an automatic backup from the C: drive to MyBook (F:). And then on the fly let Smartware backup from MyBook (F:) to My Cloud Mirror. The set of BU files differ.

No, smartware can only back up fixed local drives, so your second one won’t be possible.

Thanks Darren, that’s what I thought. In any case, I have found a BU-software (ViceVersa) that replicates and/or synchronizes data between all the three of my physical drives.
