There is now more evidence supporting that there are no backups, e.g. he doesn't even store information about which servers he already looted (he is erasing the same servers twice or more). Until someone has logs that prove otherwise on bigger datasets, nobody should pay this guy. Also it seems implausible seeing the vast amount of data which he would need to have backed up, closing in several hundreds of terabytes, based on an estimation of last year.
