Storage node to Satellite : I've lost this block, sorry

[Pentium100]

This is similar to my idea about restoring from backup.

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…

But yeah, I would like to at least have a list of pieces my node is supposed to have so I can check myself to see if there is some data loss going on.
