I have a Synology 4-bay san that has 4 2-tb drives in a raid stripe. I backup to that. I
do convert software cd’s and dvd to .iso and floppies to .img and copy the results to the
san.

I do many backups on blu-ray DVD's, the theory is if they start to go bad, maybe
partial recovery of important files will be possible due to having many copies on DVD.
This is getting a bit difficult as the amount of stuff to be backed up is just a bit too
big for a single blu-ray disc.
I also do much more frequent backups to a large hard drive.

That reminds me (looks at 43.5T of zfs pool that
has not had a scrub
since 2021).
It can be nice to have a filesystem which handles redundancy and also
the option to occasionally read all the data, check end to end
checksums (in the unlikely case a device returns a successful read
with bad data), and fixup everything. Does not eliminate the need for
remote copies, but gives a little extra confidence that the master
copy is still what it should be :)
So, what else do you guys use, to make sure your data is safe for the years to come?
