The backup feature in klok is not meant to sync multiple pcs. The reason Klok creates a new backup file when you attempt a restore is because we designed klok to backup again before you restore in case the restore fails for whatever reason. ( kind of like a Microsoft restore point in Windows before you install software) To manage or sync to more than one pc you will need the Klokwork team console and team connector. We are releasing these programs very soon. Please stay tuned.
