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

At the moment it’s not worth it as explained by BrightSilence in the previous post.
When your node started to fail audits because of missed or corrupted data, there is a high probability that all remained data is affected too. To make sure the satellite must download every single piece to check it, for the same price as a repair. But unlike repair, the audit worker will not recover piece if it’s corrupted.
And the repair job may be never triggered for this segment, if the customer would delete it.
