    Abstract: Systems and methods provide failover operations for witness sled hardware installed in a chassis. The chassis may include data storage devices and Information Handling Systems (IHSs), each storing data redundantly to the storage devices, such as in a vSAN. A primary witness sled provides witness functions, such as arbitrating discrepancies in the redundantly stored data. The chassis includes a chassis management controller (CMC) that connects with the primary witness sled via a management signaling pathway and maintains a copy of witness transactions stored by the primary witness sled based on transactions transmitted via the management signaling pathway. The CMC generates an inventory of co-located witness sleds. Upon detecting the primary witness sled is not operational, the CMC selects a failover witness sled from the inventory of co-located witness sleds and migrates witness operations of the primary witness sled to the selected failover witness sled.

    Abstract: An illustrative cloud-based air-gapped data storage management (destination) system obtains authorized access to other (source) systems' backup copies, replicates those copies within the destination system, parses supplemental metadata included in the source backup copies, and integrates the replica copies into the destination system as though natively created there. Replica copies are integrated as backup copies without first restoring the source backup copies to a native data format. The source system lacks knowledge of or connectivity with the destination system, thus maintaining an “air gap” between the systems. The destination system preferably operates in a cloud computing environment. The destination system uses supplemental metadata from the replica copies to re-create or mimic the source's computing environment and to restore backed up data from the replica copies. The destination system also operates as an autonomous analytics engine, applying value-added services to backed up data pulled from source system(s).

    Abstract: An illustrative method of container layer storage management includes coordinating a storing of container images in a first storage system; forming a dataset for a containerized application by instructing the first storage system to merge collections of files from a set of source datasets including at least one immutable source dataset; receiving a request for the dataset for the containerized application for recovery of the containerized application from a first server cluster to a second server cluster; and coordinating, in response to the request, a providing of access to a copy of the dataset of the containerized application, by a second storage system, to servers in the second server cluster to enable access by the containerized application on the second server cluster.

    Abstract: A site and storage tier aware technique replicates data as one or more recovery points (RPs) from a primary site to a secondary site in a multi-site data replication environment. A storage tier aware reference resolver determines (i) an amount of RP data transfer associated with the replication and (ii) location information associated with a cloud storage tier storing the RP data in an object store. The storage tier aware reference resolution aspect provides two additional factors to consider when retrieving data of a reference RP from cloud storage: (iii) the time (duration) needed to retrieve the data and (iv) the cost (financial expense) needed to retrieve the data. In addition, a site aware reference resolution aspect of the technique determines an optimal RP to use as the reference RP and involves consideration of (v) which RPs have been replicated from the primary site to the secondary site and (vi) which RPs have been retained for storage at the sites.

    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.
