Business Continuity:
The Role of Tape Technology in Protecting Corporate Assets
Would your business survive a disaster?• Depending on the industry, researchers have shown that for every 8 hours a
business operation is down, the firm loses .5% market share.• The Insurance Institute for Property Loss Reduction estimates that 50% of
businesses that suffer major disasters are unable to resume operations.• According to a survey of over 1,800 large and small businesses in five major
business sectors by the University of Delaware’s Disaster Research Center, electricity is the most critical lifeline service for business operations.
– The Center estimates that business interruption losses from power outages alone are $3 billion to $5 billion annually.
• Floods, earthquakes and tropical cyclones account for 90% of the world’s direct losses.
• Insured losses from 2000 to 2002 jumped from $7.5B to $11.5B
Causes of disruption
• application failure • operator error • virus and hacker attack • theft or sabotage• hardware or system failure • natural disaster

What is 400GB of LTO cartridge capacity?• Storage for 50,000 MP3 songs or 600 CDs• A stack of 1.44MB floppies half a mile high• A week of continuous DVD movies• If 1 byte represented 1 sheet of paper, it's a stack of paper
26,400 miles high• If 1 byte represented 1 heartbeat, it's 1 minute’s worth of all the
human heartbeats on earth• 3000 times more data than a human brain retains in a lifetime• If 1 byte represented 1 grain of sand, it's enough sand to fill a
96-ton mining truck
Is tape fast?“Another factor in the mix is the growing speed of tapes...Now it
has changed to: Can your disk keep up with your tapes?” Technical Support, Dec. 2002, Perspectives in Storage, by Ira Goodman
