I just need to preserve some old data that I have on my computers, so I was wondering what would be the best way to archive stuff long term.
Blu-ray disks ? Multiple HDDs ? What do you guys suggest ?

Fair enough if using a more expansive version of hardware failure. Things like a house fire would presumably destroy a series of optical disks which would make most any in house option non-functional. Network based backups could also fail to transmit data securely and accurately as well so really any sort of replication solution needs validation of the data is of significant value. A first step in preservation is to not have the box that it came from burn down, and have a way to recover if someone does a ‘sudo rm -rf /’ accidentally.
Well, it makes any option that only uses a single location non-functional. Having two copies at home and one at a distant location (as recommended by the 3-2-1 backup rule of thumb) mitigates this issue.
Absolutely. Though the network is usually assumed to be unreliable from the get-go, so mitigations usually already exist here (E2EE, checksums, ECC).
Absolutely correct. An untested backup is probably better than nothing but most definitely worse than a tested backup.
Certainly something that must be mitigated but this is getting out of “hardware failure” territory now ;)
