Re: Enabling data deduplication on Swift


Restricting fingerprinting to blocks would make block level compares possible, but as I noted on an earlier reply
it would *always* require that the blocks be transferred to perform the calculation. It is a lot harder to double
Network bandwidth than to double storage. Deduplication that only saves disk space is leaving the larger problem
of network bottlenecks unaddressed.
