A storage appliance arranges snapshot data and snapshot metadata into different structures, and arranges the snapshot metadata to facilitate efficient snapshot manipulation, which may be for snapshot management or snapshot restore. The storage appliance receives snapshots according to a forever incremental configuration and arranges snapshot metadata into different types of records. The storage appliance stores these records in key-value stores maintained for each defined data collection (e.g., volume). The storage appliance arranges the snapshot metadata into records for inode information, records for directory information, and records that map source descriptors of data blocks to snapshot file descriptors. The storage appliance uses a locally generated snapshot identifier as a key prefix for the records to conform to a sort constrain of the key-value store, which allows the efficiency of the key-value store to be leveraged. The snapshot metadata arrangement facilitates efficient snapshot restore, file restore, and snapshot reclamation.

Snapshot metadata arrangement for efficient cloud integrated data management

Systems and methods for providing for efficient switchover for a client in a storage network between the use of one or more a primary storage resources to one or more disaster recovery (DR) resources are provided herein. Embodiments may implement synchronization between such resources on a data plane and a control plane to allow for a transition between resources to be implemented in a manner that is minimally disruptive to a client. Moreover, embodiments may provide for processing resources which allow for switching a client between a primary storage resource to a secondary storage resource with minimal administrative interaction.
