Slightly more than 60% of respondents use dedupe in backup. A few years ago almost all dedupers used an appliance, but this group is split fairly evenly among the prevailing methods: appliances lead with 20%, but deduping with backup software (19%) and virtual tape libraries (15%) aren’t far behind.
