Abstract: Techniques described herein relate to a method for performing pre-backup tasks. The method includes obtaining, by a proxy host, a snapshot request associated with an incremental backup of a file system stored in a network attached storage (NAS) from a backup manager; in response to obtaining the snapshot request: instantiating a NAS container to obtain a snapshot of the file system; providing the snapshot to the NAS container; after providing the snapshot to the NAS container: retrieving a previously generated slice list associated with the file system; identifying, using the slice list, changed data include in the file system; generating change rates associated with each slice; grouping the slices based on the change rates and group criteria to generate slice groups; generating an updated slice list specifying the slices and the slice groups; and providing the updated slice list to the backup manager.

Abstract: A cloud-native global file system, in which one or more filers are associated with a volume of a versioned files system in a private, public or hybrid cloud object store, is augmented to include a rapid ransomware recovery service. Upon detecting a ransomware attack associated with one or more files or directories of the volume, read and write access to the volume is restricted. A recovery filer is then activated or designated in the cloud. A restore operation is then initiated at the recovery filter. Following completion of the restore operation, a new clean (healthy) snapshot of the volume is then created using the recovery filer For any filer other than the recovery filer, a determination is made whether the filer has completed a merge operation with respect to the new clean snapshot. If so, read and write access to the volume is re-enabled from that filer.

Abstract: A snapshot request for a selected database is obtained by a computing device of a computing environment. Based on obtaining the snapshot request, a snapshot of the selected database is taken. Based on taking the snapshot, a snapshot identifier is recorded in metadata of the selected database. The snapshot identifier identifies the snapshot request.

Abstract: Computer-readable media, methods, and systems are disclosed for processing backup and recovery of pages in an in-memory database system employing tenant-based, group-level encryption for a plurality of tenants. Page metadata for a page may be collected. The page may comprise a header and a set of page contents. The page metadata may be stored with the page header. When a backup request is received, the page may be loaded into a backup stream. The page may be loaded with the header unencrypted and the page contents encrypted. When a recovery request is received, the data page may be retrieved from the backup stream. A converter may be rebuilt using the page metadata. The data page may then be written to the main memory of the database system. The page contents may be decrypted by the converter.

Abstract: Techniques for data management are described. A request to mount a version of a database based on data stored at a computing system may be received. Based on receiving the request, a container at the computing that is configured to support operating the version of the database may be configured. Based on creating the container, a database request for the version of the database may be received at the container. In response to the database request, the container may access a set of data stored at the computing system, the set of data being associated with the version of the database. The container may output a response to the database request based on accessing the set of data.

Abstract: An apparatus comprises at least one processing device configured to identify, utilizing virtualization software running on a storage system, a snapshot lineage comprising snapshots of a storage volume, the snapshot lineage comprising (i) a local snapshot lineage on the storage system and (ii) a cloud snapshot lineage on cloud storage external to the storage system. The processing device is also configured to utilize the virtualization software to select a given snapshot in the cloud snapshot lineage to recover to the local snapshot lineage, to expose a cloud storage volume for the given snapshot, and to map the cloud storage volume to a target local storage volume on the storage system. The processing device is further configured to recover the given snapshot to the local snapshot lineage by utilizing a data mover of the storage system to write data of the given snapshot to the target local storage volume.

Abstract: Described are system and methods that provide instant access of data of a workload/container-based application, allowing the workload/container-based application to be recreated at the destination container platform. A connection is established between the destination container platform and a source storage; A volume of the container-based application is taken and stored to the source storage. A storage accessed by the destination container platform creates a proxy volume which maps and copies data of the snapshot. The data is pulled from the proxy volume as needed to recreate the container-based application at the destination host platform.
