Restore Backup with only dblock and dindex files

Nice job, amazingly fast. You might have no interest in the full metadata load, but to get timestamps, perhaps:

Take File table ID, lookup as Fileset table ID, take Timestamp, convert UNIX time

You might also run into a character translation of the / and + characters before using hash as an entry in zip. Exactly where and how this happens is of interest to me because it has signs of correlation with compact bug.
