What enables HP StoreEasy Storage to replicate only changed file blocks instead of the entire file?

File Screening Management is a File Server Resource Manager feature that restricts which file types users can save, and has no role in replication efficiency.

Cyclical Redundancy Check is an error-detection method used to verify data integrity, not a mechanism for identifying or transmitting changed file blocks.

File Classification Infrastructure automatically tags and categorizes files based on rules, but it does not control or optimize how file data is replicated.

Remote Differential Compression (RDC) is a Windows Server algorithm used by technologies like DFS Replication to compare the source and destination file at the block level and transfer only the segments that have changed. This enables HP StoreEasy to replicate file changes efficiently without sending entire files across the network.
