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.

Method and apparatus for on-disk deduplication metadata for a deduplication file system

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.
