Are there any plans for combining the running of a node and using Tardigrade to store my own data?
We have a number of integrations in the work that will make it easy to backup existing hardware to the decentralized cloud - and monetize any excess space! As per our last Town Hall, these WIP integrations include FreeNAS, QNAP, Synology, Plesk, and NextCloud.
These cyclical integrations are a way off from release. Your best bet today is to run a node, and use the payout wallet address to directly pay for data storage in Tardigrade.
“So, if I earn more money from running a node than I need to pay for storing my own data, will it be possible to get the amount taken from my earnings instead of me having to start up the Ethereum client every month to give a few tokens back.”
Due to the erasure coding of data (which drives resilience, durability, performance, and global availability) data is expanded by a factor of ~2.7x. So you will need to take that into account when calculating earnings/cost of stored data.
With a just a few GBs to backup, you should be in the clear!
