摘要： Example apparatus and methods use two types of storage to improve boot time associated with recovering a virtual machine running on a hypervisor. The first storage is deduplication based and the second storage is not deduplication based. Example apparatus and methods may read data from the first storage to support operations immediately upon the VM booting and until a full recovery has been completed. Example apparatus and methods may also write a snapshot to the second storage and then support random input/output for the virtual machine from the snapshot in the second storage immediately upon the VM booting until a full recovery has been completed. Having dual devices facilitates using deduplication storage for deduplication-centric I/O while non-deduplication storage is used for random I/O while transfer of a recovery image from a backup device to a primary device associated with the VM is completed.

摘要： Example apparatus and methods process virtual machine image level backups that may include files that are compressed and files that are not compressed. Example apparatus and methods may produce virtual machine image level backups by selectively compressing some files associated with the image while leaving other files in their uncompressed state. Example apparatus and methods may selectively recover a file or even an entire disk image from an image level backup that may include both compressed files and files that are not compressed. The file recovery or image recovery may be performed at the file level by accessing files in the image and selectively decompressing files that are compressed in the image while passing through files that are not compressed in the image. Different files in a single image may be compressed or decompressed using different techniques.

摘要： Embodiments include a data aware deduplicating object store. The data aware deduplicating data store includes a consistent hashing logic that manages a consistent hashing architecture for the object store. The consistent hashing architecture includes a metadata ring and a bulk ring. The consistent hashing architecture may be a multiple ring architecture comprising a metadata ring and two or more bulk rings. A bulk ring may include a key/value (k/v) data store, where a k/v data store stores a shard of an index and a reference count that facilitates the individual approach to garbage collection or data reclamation. The data aware deduplicating data store also includes a deduplication logic that provides data deduplication for data to be stored in the object store. The deduplication logic performs variable length deduplication and provides a shared nothing approach.

摘要： Embodiments include methods, apparatus, or processors configured to access a tracking enabled storage volume associated with a container; perform a full backup of the storage volume, where performing the full backup includes defining a full backup point; perform a first incremental backup of the storage volume based on the full backup point, where performing the first incremental backup includes defining a current backup point; determine whether a backup termination condition has been met; upon determining that the backup termination condition has not been met: performing a subsequent incremental backup of the storage volume based on the current backup point; and updating the current backup point. Embodiments may restore the tracking enabled storage volume from the full backup and the incremental backups.
