Arkivum’s storage is based on the principle that 3 copies are needed for certainty that data is safe. Using active integrity checking at all times, every file is copied three times, with 2 copies held online in geographically separated data centres and the third held offline locked away in an escrow service. A gateway appliance sits on your network and delivers your archive as a file system – files are copied to and from the file system. Behind the scenes Arkivum’s systems take care of all the replication and integrity checking.
