That makes no sense whatsoever. When files are copied, to the software that performs the task, it makes no difference whatsoever whether that file is .jpg file, .nef, .dng or a string of random bytes. Whenever replication of files is done for archival purpose, it is either performed by software that automatically verifies that the original and the copy are identical, or such verification is performed independently. The likelihood of an error and means to combat it are not in any way at all dependent on the file format.

.jpg is the best long-term archival file format for photographs simply because it is so prevalent: the vast volumes of image material that is used for all kinds of purposes ensures that software that ingests and displays such files could not be abandoned easily for decades and decades to come.

The reason this was all worth mentioning is to stress something else I warned about above: unless one has a fair understanding of IT issues involved, one might end up with less than optimal solution. And if the subject is researched from the random noise on the net, one is unfortunately in danger to running into statements such as the one we are discussing here: "...jpegs seem to be less robust than other formats...".
