I interpreted your statement of "just to have plenty of backup" as having plenty of storage space rather than multiple copies / redundant backup. The problem I have had is that when one is trying to duplicate/copy > 1 Tb of data across tens, if not thousands of files, that the bitrot is not always easy to find. Windows and OS X / MacOS treat bitrot differently and, it seems, across different file types. And yeah, lots of issues with scratching, discolouration, lost, etc., of any printed or optical media. That's why a hybrid physical-digital solution is a good half-way house. Same goes for encryption keys or one's crypto wallets, best to hedge one's bets over physical and digital media.

>I interpreted your statement of "just to have plenty of backup" as having plenty of storage space rather than multiple copies / redundant backup. Yeah, plenty of backup copies. One can always die on you, and even just 2 is stretching it. And the working ones should be verified and copied to new copies every 3-4 years (but in overall, it's not a big deal). >The problem I have had is that when one is trying to duplicate/copy > 1 Tb of data across tens, if not thousands of files, that the bitrot is not always easy to find Yes, but for the order of 100s or 1000s of images (equivalent to those one would be able to print) this shouldn't be a problem though. Tiny HDs, SSDs, and USB drives + MD5 (or better) hashes/CRC codes should do.
