Abstract
Deduplication, including inline deduplication, of data for a file system can be implemented and managed. A data management component (DMC) can control inline and post-process deduplication of data during write and read operations associated with memory. DMC can determine whether inline data deduplication is to be performed to remove a data chunk from a write operation to prevent the data chunk from being written to a data store based on a whether a hash associated with the data chunk matches a stored hash stored in a memory index and associated with a stored data chunk stored in a shadow store. If there is a match, DMC can perform a byte-by-byte comparison of the data chunk and stored data chunk to determine whether they match. If they match, DMC can perform inline data deduplication to remove the data chunk from the write operation.
