Yes it's block level. IIRC down to like 64KB blocks that it does the diff at. Once you put the first image out there, you should only expect to replicate the diffs in all the other images.
Thanks, Brian Desmond [email protected]<mailto:[email protected]> w - 312.625.1438 | c - 312.731.3132 From: Christopher Bodnar [mailto:[email protected]] Sent: Wednesday, February 6, 2013 10:41 AM To: NT System Admin Issues Subject: DFSR question regarding RDC Got a question about this: http://msdn.microsoft.com/en-us/library/windows/desktop/bb540025(v=vs.85).aspx "Replicating data to multiple servers increases data availability and gives users in remote sites fast, reliable access to files. DFSR uses a new compression algorithm called Remote Differential Compression (RDC). RDC is a "diff over the wire" protocol that can be used to efficiently update files over a limited-bandwidth network. RDC detects insertions, removals, and rearrangements of data in files, enabling DFSR to replicate only the deltas (changes) when files are updated." Just curious if anyone has really looked at this in regards to the RDC feature in larger files. Got a replication set we are going to setup. These will be larger files (17-25G), they will be images for Citrix Provisioning server. Wanted to know if it's really doing delta's in larger images files as they change, or replicating the whole thing.
