For many companies, backing up and restoring email environments is becoming a slow, complicated, expensive process. The volume of data to be protected is growing 30-60% annually, while the amount of time available to complete backups is staying the same or shrinking. At the same time, end-users are more dependent on email for business-critical operations than ever. Failed backups - which happen in 20% of tape backups - and delayed file restores drive down productivity and directly affect the bottom line. Deduplication technology is changing the economics of data protection by enabling companies to backup and restore petabytes of data without adding capacity--making the cost of backing up to a VTL comparable to physical tape.
