All my video media that’s easier to replace than preserve is on my NAS running openmediavault with mergerfs. If I lose a drive I can always just, you know, torrent the tv show again.

My main PC (everything except the Steam game install directory) is backed up through KopiaUI to a folder on that mergerfs array that contains media that’s difficult/impossible to replace. Daily incremental backups.

That folder is mounted on my PC through DOKAN, which tells Windows OS that it’s a local resource (it does this more thoroughly than just assigning a drive letter to a NAS folder through Windows’ built-in system. The PC, including the “sensitive NAS media” folder is then backed up to Backblaze’s personal backup service ($99/yr, unlimited size with one-year versioning). The DOKAN step is required for this, since Backblaze doesn’t support mounted NAS drives or non-Windows systems (presumably they don’t want to use space on versioned encrypted backups of hundred-terabyte pirate movie collections).
