A take (mine) on the backup/archiving problem is that any medium that is used for this purpose will eventually be rendered obsolete and possibly unusable without going to extreme measures. My solution is to use whatever (economical) hard disk device has the most capacity and store stuff there al

The bottom line is you have to dispense with the fantasy that any media will reliably keep data for really any length of time. You must habe resundancy. You could go the optical route, but even witj redundancy I don't recommend it. If it's a small amount of data, maybe it's not such a bad idea,

The only answer that anyone can provide is redundancy. Keep 2 or 3 copies of everything on seperate external drives. Every 3 to 5 years buy new drives and transfer the data to them. Or just run checkdisk twice a year and wait for 1 drive to start popping errors. Replace it. Wait for other to fa
