1:1 Xbox backups; are they possible

does gamejack have the ability to make backups of Xbox games…or is there any other software on the market that can do this??

XBox DVDs are not readable in PC DVDroms.
Therefore no.

But, apart from the readablility (or lack of) there are no protections on XBOX media, so therefore software will not be the key to backing up XBox Games.

In final, there is no software that will make a backup of your XBox games, the correct proeccess is a little more complicated and includes far more steps.
