Disclosed herein are methods, systems, and processes to share data storage-related services between multiple deduplication systems. In one embodiment, the method comprises receiving an indication that a local file corresponds to a shared file; virtually segmenting the shared file into a plurality of data segments, where virtually segmenting the shared file generates data segment fingerprints and library virtual mapping metadata, and the library virtual mapping metadata comprises fingerprint information corresponding to each of the plurality of data segments, and at least one of a unique file identifier, an offset of each data segment, and a size of each data segment; and transmitting the library virtual mapping metadata, where the library virtual mapping metadata is configured to be used in a subsequent deduplication operation.

Sharing services between deduplication systems

Disclosed herein are methods, systems, and processes to share data storage-related services between multiple deduplication systems. A determination is made as to whether a shared file that exists in a library of shared files corresponds to a local file. In response to a determination that the shared file exists in the library of shared files, the local file is virtually segmented into data segments, and local virtual mapping metadata is generated based, at least in part, on the data segments. The local virtual mapping metadata is then stored.

The present disclosure describes implementing a virtual image file system, or IMGFS. A mount point directory is created in a local file system, where the local file system organizes files on a storage device. The mount point directory corresponds to a proxy backup image file stored on the storage device. The proxy backup image file stores an image file system. The image file system is mounted on the local file system at the mount point directory, using a virtual file system that implements an interface configured to access the image file system. In some embodiments, a notification is provided to a recovery manager that indicates the recovery manager should catalog one or more database files of the proxy backup image file. One or more database files can be restored to a second storage device, such as a group of physical disks that are managed as a single storage unit.

Restoring a database to managed storage from a proxy backup image

A system and method is provided for servicing service management requests via a general service management framework that supports a plurality of platforms (for example, Windows&#xae;, UNIX&#xae;, Linux, Solaris&#x2122;, and/or other platforms), and that manages local and/or remote machine services at system and/or application level.
