How to save a large amount of data for a long time, what’s the economics, technology, etc?
An options for storage:
- centralized (external data center/cloud): centralization risks (single point of power/failure), expensive (periodical payments);
- centralized (own data center/cloud): centralization risks (single point of power/failure), expensive / profitable (infra payments);
- decentralized (external network(s)): decentralization risks (network is critical, no network == no data), expensive (periodical payments);
- decentralized (own network(s) nodes/protocol(s)): decentralization risks (network is critical, no network == no data), expensive / profitable (infra payments);
- hybrid: some combination of decentralized/centralized storage;
In the long term, combining your own centralized and decentralized infrastructure is the best option (possibly profitable).
