So 4x18TB for HA 36TB.

Then another 2x18TB for backup.

Surely you don't have the backup in the same machine as the NAS? It should at least be in another building entirely.

Home users don't usually have the money to rent another building.

What I do for my personal setup is RAID + nightly backup (3 drives total) in one machine, and then a 4th hard drive that normally lives airgapped in a rental storage unit that I bring home and sync every 6 months or so.

The nightly backup serves to always fetch yesterday's version of any file, and deals with 99% of scenarios that I'd need a real backup.

The 1% (hackers + fires/disasters) is taken care of by the storage unit but I lose the last 6 months of changes.
