Abstract: One example method includes powering off a replica VM, taking a snapshot of an OS disk of a source VM associated with the replica VM, taking a snapshot of an OS disk of the replica VM, generating a list of blocks that includes all blocks of the source VM OS disk that have changed since a preceding cloning or snapshot process and further includes all blocks of the replica VM OS disk that have changed since the preceding cloning or snapshot process, and performing an override of the replica VM disk by writing, to the replica VM OS disk, the respective source VM OS disk values for each block in the list of blocks.

Abstract: A system can maintain a first data center in a first physical location that comprises first compute hardware, and a second data center in a second physical location that comprises second compute hardware. The system can establish an overlay network that spans the first data center and the second data center. The system can establish a group of virtualized volume identifiers that spans the first data center and the second data center, and that virtualizes physical storage volumes. The system can determine whether to process a customer virtualized workload on the first data center or on the second data center to produce a selected location, wherein the customer virtualized workload is configured to be processed on the first data center and to be processed on the second data center. The system can process the customer virtualized workload at the selected location.

Abstract: A system can determine to restore a datacenter that comprises a group of virtualized workloads. The system can determine respective associations between respective virtualized workloads and respective datastores. The system can determine to restore a first virtualized workload of the group of virtualized workloads first. The system can restore a first portion of infrastructure that corresponds to the first virtualized workload first among a group of infrastructure. The system can, after restoring the first portion of infrastructure, restore a first portion of data that corresponds to the first virtualized workload first among a group of data. The system can, after restoring the first portion of data, restore a first portion of a virtualization layer that corresponds to the first virtualized workload first among a group of virtualization layers. The system can, after restoring the first portion of the virtualization layer, restore the first virtualized workload.

Abstract: One example method includes intercepting an IO issued by an application, writing the IO and IO metadata to a splitter journal in NVM, forwarding the IO to storage, and asynchronous with operations occurring along an IO path between the application and storage, evacuating the splitter journal by sending the IO and IO metadata from the splitter journal to a replication site. In this example, sending the IO and IO metadata from the journal to the replication site does not increase a latency associated with the operations on the IO path

Abstract: Generating any point in time backups from secondary storage without native snapshot generation and providing failover capabilities from a primary storage. Data or IOs from a source are distributed to both the primary storage and the secondary storage. When a disaster occurs with one of these storages, recovery of one of the storages can be achieved using a delta marker and data from the other of the storages.

Abstract: One example method includes performing a recovery operation. A recovery operation is performed using streams rather than volumes in the cloud. Do data is written to a do stream. When the do data is applied to a cloud volume, which is a copy or replica of a production volume, data being replaced is saved to an undo stream to ensure that any PiT can be recovered using one or more of the cloud volume, the do stream and/or the undo stream.

Abstract: One example method includes accessing augmented metadata that was stored in connection with a backup dataset, analyzing the augmented metadata, based on the analyzing, creating a guide that identifies processes which, when performed, cause the restoration of the backup dataset to an unsupported target array, and presenting the guide to a user by way of a user interface. The user may then perform the actions indicated in the guide to restore the backup dataset to the unsupported target array.

Abstract: One example method includes measuring a journal distribution lag of a journal, evaluating a first operational measure at a production site, and evaluating a second operational measure at a replication site operable to communicate with a production site, based on the journal distribution lag, and the evaluation of the first operational measure and the second operational measure, determining a scale out for a consistency group of the replication site, and implementing the scale out of the consistency group.

Abstract: Masking a data rate of transmitted data is disclosed. As data is transmitted from a production site to a secondary site, the data rate is masked. Masking the data rate can include transmitting at a fixed rate, a random rate, or an adaptive rate. Each mode of data transmission masks or obscures the actual data rate and thus prevents others from gaining information about the data or the data owner from the data transfer rate.

Abstract: One example method includes using a primary key to encrypt a decryption key, splitting the primary key into ‘n’ parts, where at least ‘k’ parts of the ‘n’ parts are required to restore the primary key, and ‘k’≤‘n’, storing some of the ‘k’ parts in respective locations in a production environment, and one of the stored ‘k’ parts is held by a verifier stage, receiving, at the verifier stage, a request for restoration of the primary key, where the request is received from a deployment pod and the request includes a subset of the ‘k’ parts and the encrypted decryption key, performing, by the verifier stage, a validation process concerning the deployment pod, and restoring, by the verifier stage, the primary key, wherein the primary key is restored using the ‘k’ part held by the verifier stage.
