Cannot Locate Area to Estimate Backup Size

I was told that Acronis Backup and Recovery Advanced Server 10 would show me an estimate of the amount of disk space required to do my backups on various servers. I can't find that estimate. I found an area to force it not to exceed a certain size (split the files) but nowhere does it seem to say how much total space it thinks it will take.

I have a basic home version that does it and was told that the robust business version did it as well. Does anyone know where that estimagte is supposed to show up? I even started a backup to see if it only performes the estimate when a backup is first staretd but still no luck.

This seems like an easy one but I can't find it in the help file nor searching various terms on this forum (estimated disk space, estimated disk usage, how much space, etc.) and is a big obstacle toward me testing this product. Using trial of build 10.0.13545. Thanks to anyone who has some advice for me. Perhaps I can pay it back and help others once I learn what I am doing.
