Question concerning Disk Space Savings on SQLsafe Today dashboard

On the Disk Space Savings section of the SQLsafe Today dashboard, what do the size parameters represent? The amount of savings (i.e., 140 GB for Today represents 140 GB saved), or the total raw amount (before compression) of the size of backups taken?

If the former, then to figure out the uncompressed size of backups taken, I would divide the size by the percentage?
