My backup method is likely overkill but would satisfy your 'this will be recoverable in many years' criteria. I create a multi-file 7z without much compression then run them through multipar (or another parity tool). Parity will let me later recover from bitrot assuming the drive doesn't fail. Back before torrent was used commonly, usenet was full of parity files to allow impartial downloads and uploads to be recoverable. Link to the multipar beta here https://www.livebusinesschat.com/smf/index.php?topic=6323.0 I open 7-zip file manager, locate my mod organizer folder, then click on add. Then in the 'Add to archive' window - I choose my backups folder, set 'compression' to fast (I get around 50% with this setting and it takes an hour to backup onto a platter drive), set 'archive type' to lzma2 (allows the cpu to use all cores while compressing), and set 'split to volumes' to DVD (optional but in the earlier version of parity the par file was always the same size as the largest of the input files so I am used to using split). Then hit OK. When that is finished I go into multipar, and set 'use gpu acceleration' on in options if not yet set but I don't think this works with my GPU anyways. Then in the main window - set my backups directory to the one used in 7z, set 'Media Size' to DVD, and 'sizing scheme' to variable size. Then drag the redundancy slider up until the number of files that can be reconstructed reads 2-2. This means if you lost two of the 7z files they can be fully reconstructed. Then hit create. At the end of this process I have compressed a 90 gig folder down to 50 and added back in 10 gigs of redundancy. If I really want this to be recoverable I would burn the various files to M-Disk DVDs at the end so I wouldn't be relying on a magnetic platter.
