Comment on APFS at Hacker News
I add parity archives to add some redundancy to my photographs. I've done it for years, but I think it's useful not to rely on a filesystem to handle this.
For example:
par2create -r5 -n2 example.par2 *.jpg
creates two files, between them giving 5% redundancy. I think that should be more than enough to repair bitrot within a file, but depending how many photos there are, losing a whole file could be more than 5%.
par2verify example.par2
will verify, and par2repair will repair corrupted or missing files.
