Abstract
Systems, methods, and devices are disclosed herein for data deduplication and storage. Methods include identifying first criteria associated with a data block included in a plurality of data blocks, the data block being identified based on a blockmap and an index, the blockmap characterizing a file stored in a deduplication repository, the index identifying data store identifiers, reference count data, and second criteria associated with the plurality of data blocks. The second criteria include the first criteria, and the first criteria characterize input/output (I/O) activity associated with the data block. The methods may also include identifying data stores based on the first criteria, the data stores being included in data storage tiers. The data stores are identified based on the I/O activity associated with the data block. The methods further include updating the first criteria stored in the index and associated with the data block.
