Looks like this would be it, but how do I view it? After the last major update, it gives you a SSH cmd to view it via SSH, so closing the browser doesn't do anything but lose the progress screen on a browser. It is still available with the SSH cmd. I am pretty sure the cmd incorporates the number I found here, but don't know the rest. If I had a spare server, I am sure I could figure it out by doing another multiple legacy restore and looking at the cmd it gives you and modifying it with this info.
Also, as a side question, why does it take so long now to do these restores? These used to get done within 12 hrs before the update, now most of them get stuck on Horde preferences for over 12 hrs. The server that creates the backups is on the same version of everything so it's not like it has to up-convert Horde stuff to a new version or anything.
