I already dropped Backblaze over this stuff and I do not intend to ever consider using them again.
Now, I:
- Put important stuff in a SyncThing folder and sync that out to 2 different nodes.
- Clone stuff to an encrypted external drive at home.
- Clone stuff to an encrypted external drive at work and hide it out in the datacenter (fire suppression, HVAC, etc).
It's janky but it works.
I used to use a safe deposit box but that got too tedious.
