No question here.. just an answer.
I wanted to set up the backup user to upload the backup content for my site.
Click here for the DH info
I kept thinking I'd find it in the Manage Users in the top toolbox part of the left nav panel.
AH..but it's not there.
You have to go to the full nav for Users, halfway down the left nav panel
and there in the drop down, you'll find link to set up Backup Users.
Frustrating to not find it.. and not find an answer here.. so I'm just adding it.
