If there was any doubt in my mind that data deduplication is a mainstream technology, it was wiped out when I saw–in the business section of The New York Times last week–a full-page ad from Symantec touting its deduplication technology. Even so, I still occasionally run into people who consider deduplication to be a dangerous form of black magic that is likely to mangle their data and end their careers. This attitude represents an overestimation of the likelihood of a hash collision in deduplication and of the reliability of more traditional backup media.
