Tape is Ideal for Disaster Recovery and Archive
Tape is decoupled from sources of corruptionTape offers data integrity validation
– detects corrupted data before it is written to tape and simplifies digital auditing
Tape is the ultimate “Last Line of Defense”– far more reliable than disk and better suited for environmental disasters
Tape offers extreme scalability at the lowest cost– simple and low cost to add cartridges instead of disk appliances
Tape eases technology migration– offers longer technology lifecycles and the ability to reuse existing media
Security, Reliability, and Predictability When You Need it Most
