ALTO is an offline, cold storage archive - a secure and convenient alternative to data tape, optical disk, and cloud for Petabyte sized volumes of valuable media assets.  ALTO uses data file replication to create multiple non-segmented replicas of your files on removable media. ALTO systems can be distributed between your premises and other geographically separated locations. Disks can be barcoded and externalized to vault storage for air-gap security providing a copy of last resort for disaster recovery.  It is widely accepted that with today's high-capacity disks, RAID storage, and your archive hard drives can leave your content vulnerable to lose. Clustered storage and Object storage can largely eliminate the risk but with a much higher lifetime cost of ownership. ALTO offers an outstanding combination of ultra-high security, with an ultra-low lifetime cost of ownership, future-proofing your investment, and minimizing your carbon footprint.
