A second offsite NAS (my old one) with the same capacity for the larger files
Backblaze B2 and a Hezner storage box for Really Important stuff.

So you have 56TB of total storage, but how much of that 56TB is actually used? Take the amount of storage used and add 10-12% to that figure. Now you create a new NAS (preferably off-site) with that amount of storage and that becomes your backup target. Take an initial backup (locally if possible to speed up the process) and then you can use something like rsync to create incremental backups going forward. This is the method I've used and so far it has worked out well. I target 10-12% more than the amount of used storage for my backup capacity because my storage use grows reasonably slowly. If your usage grows faster you might want to increase your "buffer" a little more so that you're not having to constantly add drives to your backup target.
Yeah, this is certainly a viable "brute-force"-ish ooption. While I have 56, I'm only using 26 or so. But I'd actually be hesitant to do anything less than a full capacity mirror because I do expect to eventually use this (and more - adding drives to Unraid).
I've balked because of cost and upkeep (maintaining the same capacity, additional chances for drive failure, two separate sites I need physical access to with a high bandwidth connection), so I admit I was hoping I was missing an easier option.

I have a 120TB unraid server at home, and a 40TB unraid server at work. Both use 2 x parity disks.
The critical work stuff backs up to home, and the critical home stuff backs up to work.
The media is disposable.
Both servers then back up to Crashplan on separate accounts - work uses the Australian server on a business account, home used the US server on a personal account.
I figure I should be safe unless Australia and the US are nuked simultaneously.... At which point my data integrity is probably not the most pressing issue.
why is your work stuff at home and why is your personal stuff at work ಠ_ಠ
Yeah I guess it probably makes more sense when it's my business.... Maybe not if you're an employee at some corporate randomly hosting backups of your dog photos.
I dunno. At a big company they probably won't notice an extra TB of storage cost... So long as you're discrete with the transfers.
The stuff that I actually care about are automatically backed up twice, once to a simple external on site and once to a cloud. The cloud rotates between the most recent backups so it never takes up more than 1tb compressed, while the local external keeps backups for much longer (something like 6tb at a time).
Zfs send. Done
Definitely following this
I don't for media. I have 2 parity drives and that's it. I'd like to do some kind of off site mirror but I haven't had time to figure it out and buying enough storage to do that is expensive.
My actual data for like taxes and stuff is backed up to my server and backblaze.
I've started using k8up to save my photos and config to an encrypted restic repo in an s3 bucket. having a lot of trouble backing up my SQL DB though, not as easy as they make it sound.
