Disk Backup Problems Abound - Users Want more Space NOW
Fed up with slow tape backup systems and under pressure by regulators and auditors to keep data online and readily available, large and midsize businesses are making disk-to-disk backup technology a top priority in their data centers this year.
More than 75% of 150 large companies recently surveyed by TheInfoPro Inc., a New York-based independent research firm, said disk-to-disk backup technology is being used in their data centers; this compares to 67% who were implementing it a year ago.
Still, in the most recent survey, only about a third said they are using virtual tape libraries (VTLs), a form of disk-to-disk backup that essentially uses disk arrays to mimic tape for server backup jobs.
One in four IT managers surveyed said they believe poor archiving practices are a key reason for unchecked data growth. The average company has 250TB of active storage space dedicated to archive-related content. Moreover, the survey found that archive capacity among companies is expected to grow by 52% by the end of this year.
Sean O’Mahoney, manager of client-server computing at Norton Healthcare Inc., Louisville, Ky.’s largest health care system with more than 2,000 physicians, rolled out three disk-to-disk backup systems over the past year. It helped the organization deal with a 50% year-over-year archival data growth rate that pushed the backup window to 20 hours a day.
