StoreGrid. Peer 2 Peer backup software, using ‘robust’ encryption and ‘trusted peers’. Doesn’t look too bad actually, although the free version doesn’t have remote backup capabilities which is a shame.
StoreGrid’ P2P deployment capability is based on the concept of trusted peers in an intranet whose desktop space can be utilized in a peer-to-peer fashion. Another important feature of StoreGrid is the ease with which end users can configure backups and restore them, when required, without the help of system administrators.
