Had a user try to do a restore to Virtual Box from an image. In doing so he received a “unexpected end of stream” error.

It seems when setting up the plan, under manual restore, we need to choose the first full “backup type” from the list of available options.
In this image we choose the 3rd from the bottom block level, and this failed with the “Unexpected end of stream” error. You cannot choose both.

I would think that this would restore based on the age of those files, and if I choose the full options, but your not able to choose both the full and the previous block level, so why is it there?
By choosing the “Full” backup type the restore ran fine.
