    摘要: Systems and computer program products are provided for optimizing selection of files for deletion from one or more data storage devices to free up a predetermined amount of space in the one or more data storage devices. A method includes analyzing an effective space occupied by each file of a plurality of files in the one or more data storage devices, identifying, from the plurality of files, one or more data blocks making up a file to free up the predetermined amount of space based on the analysis of the effective space of each file of the plurality of files, selecting one or more of the plurality of files as one or more candidate files for deletion, based on the identified one or more data blocks, and deleting the one or more candidate files for deletion from the one or more data storage devices.

    摘要: Methods, systems, and physical computer-readable storage medium are provided to optimize WAN traffic on cloud networking sites. In an embodiment, by way of example only, a method includes fetching deduplication information from a home site to build a repository comprising duplicate peer file sets, one or more of the duplicate peer file sets including one or more peer files, referring to the repository to determine whether a target file corresponds with a cache copy of a peer file of the one or more peer files included in the duplicate peer file sets, and creating a local copy of the peer file of the one or more peer files, if a determination is made that the target file corresponds with the cache copy of the peer file of the one or more peer files included in the duplicate peer file sets.

    摘要: One method includes assigning a pointer from multiple logical blocks to the same original physical block if the multiple logical blocks include the same data. The method further includes receiving a command to write data to the first logical block and determining if the first logical block is a frequently accessed logical block. If the first logical block is a frequently accessed logical block, ownership of the original physical block is assigned to the first logical block. If ownership is established, the method includes copying any data stored in the original physical block to a new physical block, assigning a pointer from a second logical block to the new physical block, and performing the write command on the original physical block. A system includes a processor for performing the above method. One computer program product includes computer code for performing the method described above.
