Abstract: An illustrative method includes a data protection system detecting a request provided by a host to perform an operation with respect to a storage system, detecting, based on the request, an anomaly associated with the host, and directing, based on the detecting the anomaly associated with the host, the storage system to generate a recovery dataset for data maintained by the storage system.

Abstract: Storage bandwidth for a storage system process is adjusted responsive to an input output (I/O) write request to write data to a zoned storage device. The storage bandwidth is adjusted by calculating an allocation share for the storage system process requesting to write the data and opening a new zone for the storage system process upon determining that an open zone usage by the storage system process is under the allocation share for the storage system process.

Abstract: Methods and systems for transitioning a replica of a file system are described. An illustrative method includes updating a replica file system on a target data repository to be a replica of a source file system as the source file system existed on the source data repository at a point in time, where the replica file system is constructed of block objects at the target data repository that store metadata for individual files and directories of the replica file system and support access to blocks of data associated with the files and directories of the target file system at the target data repository, and where the updating includes updating the block objects of the replica file system to be replicas of block objects of the source file system as the block objects of the source file system existed on the source data repository at the point in time.

Abstract: Data resiliency in a cloud-based storage system, including: receiving, for storage within a first tier of cloud storage of the cloud-based storage system, one or more segments of data; generating, for each of one or more shards of data of the one or more segments of data, self-describing information for recoverability of the one or more shards of data; and storing, within a second tier of cloud storage of the cloud-based storage system, both the one or more shards of data and the generated self-describing information for recoverability of the one or more shards of data.

Abstract: Multi-path end-to-end encryption in a storage system, includes: receiving, by a storage system through a first path, a first write request for first data to be stored in a dataset, where the first data is encrypted with a first encryption key associated with requests received from the first path; decrypting the first data utilizing the first encryption key; encrypting the first data using a storage system encryption key; storing the first data in the dataset; receiving, by the storage system through a second path, a second write request for second data to be stored in the dataset, where the second data is encrypted with a second encryption key associated with requests received from the second path; decrypting the second data utilizing the second encryption key; encrypting the second data using the storage system encryption key; and storing the second data in the dataset.

Abstract: A storage system establishes a staging region, for temporary writing of arriving data, and a stable region, for transfer of data from the staging region, in storage memory. The storage system establishes resiliency groups, each with a characteristic level of redundancy that is settable on an individual basis. The storage system performs data accesses of data stripes in accordance with the staging region, the stable region, a first resiliency group and a second resiliency group.
