I'm up to 130TB of Redundant Local Storage, but trying to figure out the best way to backup the data and move offsite - for this volume of storage, the commercial cloud providers are out - it'd be several hundred dollars a month. Tapes? Build another low power server and stick it somewhere else to rysnc? What has everyone's strategy been around very large backups, ideally without crazy costs?

In reality that's what this will cost you.
Just running some quick numbers, a used LTO7 drive and tapes will be cheaper than just the raw storage for a 130TB offsite array
This. When you're in the +100TB range, tapes start to be the cheapest solution.
Whatever you can acquire cheaper: used LTO drive (but then offsite tape management can be a pita) or new low-power server, they'd both work. $20-30/TB for redundant spinning rust (or even $15/TB for non-redundant) should make tape cheaper tho.
Would opt for tape as well. For storage of that size, considering it’s a backup , tapes are made for.
Cold storage in a safe deposit box + amazon glacier
I’m afraid there are no miracles. Either a backup in the cloud, dedicated server lease or tape.
In any case, it’s going to cost you a couple of hundreds...
Let's be reasonable here. You have 130 TB of storage, which probably cost ~ 5000 USD in HDDs alone. Does it strike you as reasonable that offsite storage for $5000 of local storage would be inexpensive?
You could stick a server at a friend's place, but any server with 130 TB of storage is:
Since no medium can hold 130 TB in a single LUN, you're looking at multiple tapes or HDDs, regularly rotated offsite/onsite. You'll need at least 130 TB of drives, which also isn't inexpensive.
