Goal: back up my data and broken harddrives in a way that preserves integrity

Concern: data stored in the cloud has experienced corruption for me

Concern: objects held physically have experienced damage for me

Concern: algorithms running on local systems have experienced misbehavior for me

Concern: I do not have much money

Solution 1: make or use an interface to blockchain storage

Solution 2: find money for cloud storage and set up a system for verifying data integrity, one or the other

Solution 3: get rugged physical storage, and set up a system for verifying data integrity

Harmful behavior: I have 3 vps hosts I am paying for right now. One of them I have lost access to and support hasn't responded to any queries. It would be nice to only use 1 vps service.

Harmful behavior: I freak out when I try to back things up. I have piles of things pending backup.
