I write all my important files to an external 200 G Drive and then offsite it.

    I mount an old drive in a USB enclosure
    copy the files to it.
    remove the drive and use the factory packaging.
    and store it at someone else's house.

      Offsite, cheap, fast.

Because I do every 6 months or so, usually with a drive that I'm replacing because its too small the cost is minimal. The "archival" copy is the one on my desktop, 20 years from now, that 200G of video will take up just a small fraction of the 400T drive that I use to run Microsoft's Ultimate Galaxy OS.

I don't worry about disk/filesystem formats because if my desktop is always the "master" copy, and if it fails, it could always read the last few copies I made.
