Deduplication has moved from cutting-edge technology to mainstream staple. The data protection technology first showed up in 2003, aimed at organizations looking to move away from tape for the performance of disk-based backups. A decade later, dedupe is basically a requirement for backup products, although many companies say they still aren't using it for data protection.
Thirty-five percent of respondents in Storage magazine's last Purchasing Intentions survey said that they would be deploying deduplication technology within a year. The survey also indicates that the move away from tape as a backup medium continues. Thirty-eight percent said they plan to cut spending, while 48% intend to keep tape spending at last year's level.
