Archive-as-a-Service

• Keeping data safe and secure

• 100% guaranteed data integrity

• Arkivum infrastructure in co-lo data-centres

• Tape based storage = reliable, cost effective


How it works


Safe, Secure, Easy to Use• Data tape provides 30 year shelf life• Three copies at all times• Multiple media manufacturers• Automated tape libraries• Escrow copy

• Seamless integration• Simple network file-share• Data in pre-agreed

locations with auditable security

• Encryption in-flight and at rest• Keys managed by the customer• Media exclusivity• Secure UK based data centres running the

Arkivum infrastructure


SummaryData explosion

Up to 90% of all data could be archived
