    Abstract: Methods and systems for Vserver migration are provided. One method includes maintaining a state of a migrate operation for migrating a plurality of source storage volumes managed by a source storage virtual machine (Vserver) of a source cluster to a plurality of destination storage volumes of a destination cluster of a networked storage environment; restarting a process at a healthy node of the source cluster or the destination cluster to continue the migrate operation, in response to detecting an unhealthy node at the source cluster or the destination cluster executing the process; retrying a task associated with the migrate operation experiencing intermittent failure for a certain number of times, and upon successful execution, continuing the migration operation; and checking the state of the migrate operation and in response to the state of the migrate operation, continuing the migrate operation or restarting the migration operation.

    Abstract: A request is received to retrieve at least a portion of a file from a compressed data archived image stored in a backup storage device. The compressed data archived image comprises a backup of a file system having a number of directories and a number of files. The compressed data archived image comprises a file that includes a compression of the number of files. An address of the at least the portion of the file within the compressed data archived image is determined. The at least the portion of the file is retrieved at the address in the compressed data archived image, without decompressing the compressed data archived image.

    Abstract: Techniques are provided for replay of metadata and data operations. During initial execution of operations, identifiers of objects modified by the execution of each operation are identified and stored in association with the operations. When the operations are to be replayed (e.g., executed again, such as part of a replication operation or as part of flushing content from a cache to persistent storage), the identifiers are evaluated to determine which operations are independent with respect to one another and which operations are dependent with respect to one another. In this way, independent operations are executed in parallel and dependent operations are executed serially with respect to the operations from the dependent operations depend.

    Abstract: One or more techniques and/or computing devices are provided for restarting a dump backup. For example, a phase offset table is used to track a directory transfer phase offset and a file transfer phase offset of phases of a dump backup. An offset map is used to map inodes, of data being backed up, to offsets within a backup image within which the data is being backed up. The phase offset table and/or the offset map are evaluated using a bytes written value to identify a phase during which the dump backup aborted and to identify a restart point. Accordingly, the dump backup is restarted at the restart point. In this way, the dump backup may be restarted during any phase and/or at any point using the bytes written value, the phase offset table, and the offset map without the need for additional information such as a file history.

    Abstract: Methods and systems for Vserver migration are provided. Update after claims are finalized. One method includes generating a consistency group (CG) having a plurality of source storage volumes of a source storage virtual machine (Vserver) of a source cluster for a migrate operation to migrate the source storage volumes as a group to a plurality of destination storage volumes of a destination cluster; establishing a mirroring relationship between the source and destination cluster for managing asynchronous transfer of the source storage volumes in the CG to the destination storage volumes during a transfer phase of the migrate operation; replicating a logical interface of the source cluster to the destination cluster, the logical interface providing a network address to access the source cluster; and automatically selecting a destination port at the destination cluster, associated with the replicated logical interface.
