Duplicate job vs incremntals and their dependency to the full

Hi all,

First time I use those forum services. I hope I'm at the good place ! ;)

So here's the thing. I have this costumer where I duplicate every single jobs to an iSCSI drive which is provided by his ISP. A free out site solution in case of fire.... So each fulls is duplicated as well as the incrementals...

Once I've finished to setup this backup solution, a question came to my mind: "If we lost everything but those backup made on this iSCSI drive, when it will come the time to restore from the incrementals, Will the incrementals reconise the duplicated full as "the full" to refer to ? or it will look for the original full ?

I think it's gonna refer to the original but i'd like to have a confirmation.

Thanks !!!
