Backup files

I have 2 WD 2T Passport external drives. How can I setup backup from 1st 2T passport to the 2nd 2T passport drive.

The option that is available is from the PC Hd to the WD passport only. What I have missed? Any advise is much appreciated.

Hello,

Unfortunately WD Smartware does not support having a drive that comes with WD Smartware as source for the backup.

You can post this as an idea on the Ideas board.
