I built a NAS last winter (see spoiler below) for storing terabytes of photos that were wandering around in cloud storage from my late father. It also doubles as my HomeLab server. The important fact for my questions is that it has six 8 TB 3.5" HDDs. I'm trying to figure out my HomeLab/data 3-2-1 back-up strategy and I had a couple of questions.
Here's my NAS:
Thanks in advance,

- The 2 in 3-2-1 stands for "two different media". I often see this referred to as two different machines or a second set of HDDs, but doesn't two different media imply two different "storage" media, e.g., HDD and SDD or HDD and Blu-ray Discs?
- I have a data that is stored exclusively on my NAS (one copy). If I use a remote NAS as a backup or a cloud backup, that will (maybe) satisfy the second "media" and will definitely satisfy the remote backup (second copy), but what's the best (and most cost-effective) way to get this third copy of the data?
- I've read of folks rotating high-capacity hard drives, but there's an unreliable human element in this method.
- I could build a second NAS at home, but that's definitely not cost-effective.
- Would splitting my NAS into two storage pools and replicating to the second storage pool be a reasonable way to get a third copy of the data or does it existing on the same device defeat the point? If this is a viable option, how would you recommend I set up the storage pools (two raidz1 pools? a raidz2 pool for the working data and just a normal raid pool for the other two drives?)?
Here's my NAS:
