    摘要: A method and apparatus is disclosed herein for maintaining deduplication metadata on disk separate from an in-memory deduplication file system for a deduplication computing system. The method may include reading deduplication metadata from a first memory of a deduplication computing system. Furthermore, the method may include maintaining deduplicated data for a file system in a second memory, and maintaining the deduplication metadata that describes the deduplicated data of the file system in the first memory of the deduplication computing system, wherein the first memory is a different type of memory and separated from the second memory in the deduplication computing system. Furthermore, the method may include accessing the deduplication metadata in the second memory in response to receipt of a request by the deduplication computing system to perform a first operation with deduplicated data of the file system in the second memory.

    摘要: Techniques for fast provisioning of virtual machine images using deduplication metadata are described, including receiving a request to copy a first virtual machine to form a second virtual machine, identifying a first portion of memory comprising data for the first virtual machine; and forming the second virtual machine based on the first portion of memory comprising data for the first virtual machine, wherein forming the second virtual machine further comprises linking the second virtual machine to the first portion of memory comprising data for the first virtual machine, and implementing a second portion of memory to store data for the second virtual machine independent of the first virtual machine.

    摘要: A method and apparatus for rapid replication of deduplicated file system data is described. The method may include initiating replication of a file from a source deduplication system to a destination deduplication system, and transferring deduplication metadata for each block of the file from the source deduplication system to the destination deduplication system. The method may also include transferring an identifier file from the source deduplication system to the destination deduplication system that includes a block number corresponding to a block of the file and a unique identifier value generated from the block of the file. The method may also include receiving a data request file from the destination deduplication system, and transferring the blocks of data identified in the data request file to complete replication of the file on the destination deduplication system.
