I was chatting to a potential customer the other day, looking at the pros and cons of de-duplication methods and it’s clear to me that most people still view de-duplication with a bit of trepidation.

While the mechanics of de-duplication are complex, it’s important to understand that de-duplication should be considered as just another process running on the storage system. We trust the storage system to write the data to disk as ones or zeros, that’s rocket science, so surely we can trust the system to get the de-duplication right.
