I use offline hard drives to store files that I don't think I'll be using in the future (but don't have the heart to destroy). I direct the find command to a file to make a searchable index of the drive in case I need to find a file but am too lazy to connect the drives and search them.

Pricing is super cheap like $1/terabytes a month
Couple of questions
1) how much data are talking about? Can you fit it all on DVD or a couple of flash drives and stick in a safe deposit box?
2) I guess you’ve already answered this question but I’d consider asking yourself if life would be easier if you just deleted the data and no longer had to worry about its existence. If you’re not sure if any of it will be valuable, then maybe this in indication that the data needs to be pruned for the good stuff. Keeping it intact and secure overtime is a non trivial cost and digging deep in an archive for that one file is often a headache.
I’ll add a caveat that this second approach might seem counterintuitive, considering how easy it is to store data, and how great it can feel to pull that one file when you need it, but the question is whether this data will just be a burden over time or not.
This makes me think that I should really clean off and organize my personal computer HD
