Ability to recover part of lost data / restore the node from backup

Bad stuff can happen. A single 10TB drive can develop a few bad sectors, there could be a power failure that corrupts the database and so on. Nothing is perfect. However, under the current rules, losing a bit of data means I have to delete the rest of the data and start over. This looks like a disproportionate response - the database got corrupted somehow etc and now I have to wait a year for my node to fill back up etc. Especially since there were cases where nodes got disqualified because of…

Apart from that: your node might survive losing a few GB from 8TB.
