Dedupe Rates Matter�Just Not as Much as You Think

This story questions the value of dedupe ratios as a means of evaluating deduplication products.

"The dedupe ratio measures against what’s left after you’ve deduped. The percentage measures against the size of the data before you dedupe. Both are valid measures. It’s also true that some solutions do a better job shrinking your data than others. Dedupe solutions that do a better job should be ranked higher when you are comparing solutions. That said, comparing the claims made on vendor websites is not a very good way to find out who can actually shrink your data better. Why? Vendors lie."
