摘要： Computer-implemented methods, systems, and computer-readable media for performing optimized backups of multiple volumes are disclosed. In one example, an exemplary method for performing such a task may comprise: 1) identifying a plurality of volumes, 2) prior to backing up the plurality of volumes, obtaining information that indicates that at least one volume within the plurality of volumes comprises at least one shared region of memory that is identical to a region of memory on at least one other volume within the plurality of volumes, and 3) when creating backups of the plurality of volumes, backing up each shared region of memory a single time so that the backups of the plurality of volumes share a single copy of each shared region of memory.

The computer-implemented method may further include, for each child snapshot in the hierarchy, copying valid data in the child snapshot to the backup. The computer-implemented method may additionally include copying information that identifies a parent of the child snapshot to the backup. Various other methods, systems, and computer-readable media are also disclosed.

摘要： In one embodiment, a system comprises a plurality of nodes. On each node, a storage virtualization component may receive the I/O operations generated from local applications on the node. The storage virtualization component may transmit the I/O operation, and detect any failures that occur in the I/O operations. If a failure is detected, the storage virtualization component may cooperate with other storage virtualization components on other nodes to successfully complete an I/O operation that experiences a failure. In one embodiment, if the I/O operation is successful on a remote node, the storage virtualization component may migrate the application that sourced the I/O operation to the remote node. In other embodiments, the storage virtualization component may monitor I/O operations and migrate the application after a pattern of local failures and successes on the remote node.

摘要： Prior to overwriting a block of data in a first volume of data on a primary host, the block of data is written to a first snapshot of the first volume. Subsequently, the first snapshot can be synchronized with a snapshot of a second volume of data on a secondary host, where the second volume is a replica of the first volume. To synchronize the snapshots, only a portion of the first snapshot (e.g., the block of data that was written to the first snapshot) is sent to the secondary host.
