Abstract: Generally described, one or more aspects of the present application relate to a public snapshot service for creating and managing block-level snapshots on a cloud provider network. Storage locations for each block that comprise the snapshot can be enumerated on a snapshot manifest. Identification of storage location for a requested snapshot block can be improved using a manifest index.

Abstract: Systems and methods are provided to implement a metadata record migration system that schedules the migrations of metadata records that are frequently mutated. In embodiments, the scheduler collects timing data of jobs that modify the metadata records, including the timing of various mutation operations within the jobs. In embodiments, when it is determined that a metadata record is to be migrated to a different storage location, the scheduler determines a time to migrate the metadata record. The migration time may lie within a migration window, selected based on an expected migration time needed for the metadata record and the collected time data in order to reduce a probability that record mutations will occur during the migration. In embodiments, the jobs may be snapshot jobs that modify a snapshot record, and the migration may be performed as a result of a cell partitioning operation occurring within the snapshotting system.

Abstract: A data storage service redundantly stores data and keys used to encrypt the data. Data objects are encrypted with first cryptographic keys. The first cryptographic keys are encrypted by second cryptographic keys. The first cryptographic keys and second cryptographic keys are redundantly stored in a data storage system to enable access of the data objects, such as to respond to requests to retrieve the data objects. The second cryptographic keys may be encrypted by third keys and redundantly stored in the event access to a second cryptographic key is lost.

Abstract: Conditions are enforced to prevent unintended deletion of data stored by a data storage system. For example, to delete a collection of data, a condition on the collection of data's size may be enforced. The collection may be required to be empty, for example. In addition, a condition that there not exist a pending data processing operation that can affect fulfillment of the condition on the collection of data's size is also enforced.

Abstract: Systems and methods are described for use of reserved storage capacity at a cloud provider network extension, sometimes referred to as a provider substrate extension (“PSE”) or “outpost”, as a data cache, thereby improving performance of the PSE. The reserved storage capacity may be reserved for a primary purpose, such as data replication in the event of failure of an in-use portion of the PSE's storage capacity. During non-failover operation, the reserved storage capacity may be otherwise unused. Embodiments of the present disclosure enable the reserved storage capacity, when not used for its primary purpose, to be used as a data cache to store information potentially used at the PSE.

Abstract: Systems and methods are provided for efficient handling of user requests to access shared resources in a distributed system, which handling may include throttling access to resources on a per-resource basis. A distributed load-balancing system can be logically represented as a hierarchical token bucket cache, where a global cache contains token buckets corresponding to individual resources whose tokens can be dispensed to service hosts each maintaining a local cache with token buckets that limit the servicing of requests to access those resources. Local and global caches can be implemented with a variant of a lazy token bucket algorithm to enable limiting the amount of communication required to manage cache state. High granularity of resource management can thus enable increased throttle limits on user accounts without risking overutilization of individual resources.

Abstract: Systems and methods are provided for conducting incremental restore operations on block storage volumes using an object-based snapshot. A full restore from an object-based snapshot can include copying all blocks of a data set from the object-based snapshot to a destination volume. For high capacity volumes, full restores may take large amounts of time. Moreover, full restores may be inefficient where a destination volume already contains some data of the snapshot. Embodiments of the present disclosure provide for incremental restore operations, where a delta data set is transferred from the snapshot to the destination volume, representing data in the snapshot is not known to already exist on the volume or another available volume.

Abstract: Techniques for consistent resource visibility during inter-cellular migrations using targeted pairwise scatter-gather techniques are described. For a paginated request to describe resources existing in cells of a provider network that match one or more criteria, a set of candidate cells having, or likely to have, resources of interest that match the one or more criteria are identified. Pairs of the candidate cells that are determined to be involved in a migration are jointly queried according to a scatter-gather type approach and aggregated via a union technique to remove duplicate resource entries. Other cells not involved in a resource migration are independently queried.

Abstract: Generally described, one or more aspects of the present application relate to a public snapshot service for creating and managing block-level snapshots. For example, the public snapshot service can create a snapshot based on (i) a specification of a parent snapshot to be used as a basis for a given snapshot, and (ii) a specification of the data blocks to be backed up in the given snapshot. The data blocks in the snapshot may be stored in a specific storage path structure that facilitates computation of a block difference with respect to the parent snapshot.
