Backing up another external drive to the WD Live

Hi all.

I have the WD Live Duo attached to my network.  I am using this as a storage drive and as the Time Machine backup to my imac. I have another external drive attached to the Mac that I would like to backup to the WD Live drive.  Is there any way to establish the connection between these drives or do I need 1. another software package to organize all this, or 2. to copy file manually to the external drive.

If this requires more software (grr) do you have any recommendations?

Thanks!

Greg.

Hi, you will need to use another program, you can see if Sync!Sync!Sync! works for you.
