. Fifty-seven percent of our survey respondents say they're deduplicating
, with an average of 2.8 years experience using the technology. Dedupe vendors may
tout reduction ratios that strain credulity, but our group sees an average data reduction of 27:1,
which helps reduce the amount of disk
capacity they need for backup
by an average of 44%. For restoring deduped data, 76% say it's
the same or easier than restoring non-deduped data and only 15% note that it's a little to
considerably tougher. Does it sound too good to pass up? Forty percent of non-dedupers don't see a
