Abstract: An object store service is operated as a front-end to a bucket on a first object store, wherein object store operations for the bucket are issued to the first object store. Content of the bucket is migrated from the first object store to a second object store, wherein operations to store additional content to the bucket are issued to the second object store. Subsequent object store operations for the bucket are issued to the second object store upon completion of the migration.

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: A system and method for efficient use of zones in a storage system. The method includes: building a frontier set comprising one or more zones of one or more storage devices for writing to; writing data to at least one zone of the one or more zones included in the frontier set; and during a bootup sequence: accessing a frontier set list to identify the one or more zones in the frontier set; and scanning the one or more zones to identify the at least one zone that data was written to.

Abstract: A list of a available zones across respective SSD storage portions of a plurality of zoned storage devices of a storage system is maintained. Data is received from multiple sources, wherein the data is associated with processing a dataset, the dataset including multiple volumes and associated metadata. Shards of the data are determined such that each shard is capable of being written in parallel with the remaining shards. The shards are mapped to a subset of the available zones, respectively. The shards are written to the subset of the available zones in parallel.
