Data deduplication in a removable storage device
Abstract:
An apparatus and associated methodology contemplate a data storage system having a removable storage device operably transferring data between the data storage system and another device via execution of a plurality of input/output (I/O) commands. A commonality factoring (CF) module executing computer instructions stored in memory assigns a CF tag to a data pattern in the transferred data. A deduplication module executing computer instructions stored in memory determines if the data pattern corresponding to the CF tag is previously stored in the removable storage device.
