Abstract
A method is used in managing inline data de-duplication in storage systems. The method receives a request to write data at a logical address of a file in a file system of a storage system. The method determines whether the data can be de-duplicated to matching data residing on the storage system in a compressed format. Based on the determination, the method uses a block mapping pointer associated with the matching data to de-duplicate the data. The block mapping pointer includes a block mapping of a set of compressed data extents and information regarding location of the matching data within the set of compressed data extents.
