Abstract: The disclosure provides a method for virtual volume (vvol) recovery. The method generally includes determining to initiate recovery of a compromised vvol associated with a virtual machine (VM), transmitting a query requesting a list of snapshots previously captured for the compromised vvol, receiving the list of the snapshots previously captured for the compromised vvol and information about one or more snapshots in the list of snapshots, wherein for each of the snapshots, the information comprises an indication of at least one change between the snapshot and a previous snapshot, determining a recovery point snapshot among snapshots in the list of the snapshots based, at least in part, on the information about the one or more snapshots, creating a clone of the recovery point snapshot to generate a recovered virtual volume, creating a virtual disk from the recovered virtual volume, and attaching the virtual disk to the VM.

Abstract: The disclosure provides a method for virtual volume snapshot creation by a storage array. The method generally includes receiving a request to generate a snapshot of a virtual volume associated with a virtual machine, in response to receiving the request, preparing a file system of the storage array to generate the snapshot, wherein preparing the file system comprises creating a delta storage structure to receive write input/output (I/O) requests directed for the virtual volume when generating the snapshot of the virtual volume, deactivating the virtual volume, activating the delta storage structure, generating the snapshot of the virtual volume, and during the generation of the snapshot of the virtual volume: receiving a write I/O directed for the virtual volume and committing the write I/O in the delta storage structure.
