Thanks! Good to see par2 also mentioned there.

Dont know much about *nix compression but keen to hear about other’s opinions.

I would suggest looking at par files for your corruption concerns. They would add overhead both in time and space but well worth it. I checksum everything I back up so that I can verify it. And par larger files so a bit flip, or more realistically a bad sector or two (thousand) doesn’t break everything.

Thats so when the auto drive hits another pedestrian, the car can say “I did nazi that guy”.

Are you sure that the DVD drive is a desktop 5.25 half height?

A lot of modern desktops use a laptop DVD drive now a days. That will only have room for a 2.5" drive, not a full 3.5"
