Disk Backup's a Red-Hot Idea

A whopping 84 percent of respondents to the most recent Byte and Switch poll say they're either already using disk-based backup or plan to do so in the next 12 months -- indicating that as a concept, at least, it's catching on rapidly.

According to the results of our May poll, just 19 percent of 103 respondents say they're using disk for backup purposes today. But another 65 percent say they expect to adopt it within the next year. Only 16 percent say they didn't see the need for it yet. (For more on this topic, see our report, Disk Backup 101.)

"It really suggests that people are getting this message faster than I would have guessed," says Kevin Daly, CEO of Avamar Inc., a startup that sells a disk-based backup system called Axion (see Avamar Gets More Dough).

The primary driver for disk-based backup, according to our poll, is faster recovery times, with 47 percent agreeing that shrinking the recovery window is the primary benefit of the technology. Meanwhile, 24 percent picked shorter backup windows; 18 percent said the ability to store vast amounts of data online was most attractive; and 11 percent agreed that "it's so dang cheap, why not?"

Dave Kenyon, product line manager for enhanced backup solutions at Quantum Corp. (NYSE: DSS) -- which sells both disk and tape systems for backup -- says enterprise users are increasingly interested in reducing the amount of time it takes to restore data.
