A method, system and computer program product for backup assignment of a mobile electronics device is disclosed. In response to one or more device assignment requests received by a controller apparatus when a server is operating in an off-line mode, one or more device assignment records are created within the controller apparatus, and which indicate assignment of the at least one mobile electronics device to a respective one or more users. When the server is operating in an off-line mode such that communication between the controller apparatus and the server is off-line, the one or more device assignment records, in relation to the at least one mobile electronics device, are stored in the controller apparatus. In response to the server re-entering the on-line mode, the server is updated with the one or more device assignment records.

Data recovery systems and methods utilize object-based storage for providing a data protection and recovery methodology with low recovery point objectives, and for enabling both full recovery and point-in-time based recovery. Data generated at a protected site (e.g., via one or more virtual machines) is intercepted during write procedures to primary storage. The intercepted data is replicated via a replication log, provided as data objects, and transmitted to an object based storage system. During recovery, data objects may be retrieved through point-in-time based recovery directly by the systems of the protected site, and/or data objects may be provided via full recovery, for example, within a runtime environment of a recovery site, with minimal data loss and operation interruption by rehydrating data objects within the runtime environment via low-latency data transfer and rehydration systems.

A method for synchronous replication of stream data includes receiving a stream of data blocks for storage at a first storage location associated with a first geographical region and at a second storage location associated with a second geographical region. The method also includes synchronously writing the stream of data blocks to the first storage location and to the second storage location. While synchronously writing the stream of data blocks, the method includes determining an unrecoverable failure at the second storage location. The method also includes determining a failure point in the writing of the stream of data blocks that demarcates data blocks that were successfully written and not successfully written to the second storage location. The method also includes synchronously writing, starting at the failure point, the stream of data blocks to the first storage location and to a third storage location associated with a third geographical region.

Embodiments for a method performing data migration such as backups and restores in a network by identifying characteristics of data in a data saveset to separate the data into defined types based on respective characteristics, assigning a data label to each defined type by receiving user selection or automatically merging or selecting a priority label, from among many labels associated with a file, defining migration rules for each data label, discovering assigned labels during a migration operation; and applying respective migration rules to labeled data in the data saveset. The migration rules can dictate storage location, access rights, replication periods, retention periods, and similar parameters.

One example method includes gathering respective performance data concerning each asset in a group of assets, clustering the performance data so as to define a first cluster and a second cluster, and data assets in the first cluster are assigned a HIGH RISK label and data assets in the second cluster are assigned a LOW RISK label, assigning a respective risk score to each of the assets, and the risk score includes a quantified risk level for the asset to which the risk score has been assigned, ranking the assets with the HIGH RISK label according to their respective risk scores, and backing up a ranked asset based on an IO volume associated with that ranked asset.

Methods and systems of scanning for resources for resource classification in a multi cloud environment are disclosed. For a combination of a cloud account, a cloud region, and a resource type, a percentage of protected existent resources hosted on the cloud computing platform is determined. A cycle skip count is set based on the determined percentage of the protected existent resources hosted on the cloud computing platform. The percentage of the protected existent resources and the cycle skip count associated with the combination are stored in a catalog. For the combination of the cloud account, the cloud region, and the resource type, the protected existent resources hosted on the cloud computing platform are periodically scanned for based on the cycle skip count.

Provided are a database information backup method and recovery method, an electronic device, and a computer-readable storage medium. The backup method includes the following steps: a server receives a backup task instruction and mounts a storage volume to a client; the client receives the mounted storage volume and determines whether the backup task instruction is a full backup, and if so, the client starts a CDP thread, the client starts a VSS to create a volume shadow copy; the client determines whether the backup task instruction is a full backup, and if so, the client backs up valid data in the volume shadow copy, otherwise, the client backs up corresponding data in the volume shadow copy; the server creates a storage volume snapshot and a time point; and the server unloads a mapping mounted by the storage volume.

Systems and methods are described for a non-disruptive planned failover from a primary copy of data at a primary storage cluster to a mirror copy of the data at a cross-site secondary storage cluster without using an external mediator. According to an example, a planned failover feature of a multi-site distributed storage system provides an order of operations such that a primary copy of a first data center continues to serve I/O operations until a mirror copy of a second data center is ready. This planned failover feature improves functionality and efficiency of the distributed storage system by providing non-disruptiveness during planned failover without using an external mediator based on a primary storage cluster being selected as an authority to implement a state machine with a persistent configuration database to track a planned failover state for the planned failover.

A file system and a related method are presented. The file system includes an object storage configured to store file data for one or more files and a plurality of namespace entries corresponding to file data and/or metadata of the one or more files as one or more objects. Each namespace entry of the plurality of namespace entries includes an operation type conducted on the file data and/or metadata captured in a particular snapshot and a version number corresponding to the particular snapshot. The file system further includes an indexing system configured to generate the plurality of namespace entries; store the plurality of namespace entries as one or more objects in the object storage; and identify, in response to a search query, one or more files for retrieval from the object storage based on a list of the plurality of namespace entries sorted on the version numbers.

Disclosed herein are systems and method for selectively restoring a computer system to an operational state. In an exemplary aspect, the method may create a backup image of the computer system comprising a set of data blocks, and create and start a virtual machine based on the backup image. The method may identify a subset of the data blocks accessed from the backup image during startup of the virtual machine. In response to determining that the computer system should be restored, the method may restore the subset of the data blocks such that the computer system is operational during startup, and restore a remaining set of the data blocks from the backup image after the startup of the computer system.
