Client side Dedup, very slow to start backup

Hello,
what about backup time as a whole - I guess that with the client dedup the overall backup time is shorter, despite the slow start - is not? Then I won't worry about this detail..

For client-side dedupe the client has to verify segment fingerprints with the MSDP deduplication database; whilst I believe a proportion of existing fingerprints may be cached on the client, new data will require a round trip to the Media Server to check whether it already has the new data's fingerprints. I would expect this would cause a delay before "begin writing" can actually start, but as others have said, overall backup times should be shorter and the actual amount of data transferred will almost always be much less. I would not worry about this...
