Abstract: Techniques are disclosed relating to providing protection groups and rapid determination of expired objects and associated storage resources in a cloud-based backup storage context. In various embodiments, the disclosed techniques include generating, by a computing system, incremental backup data for a backup based on protection group information, including a set of cloud-based key-value data store buckets, filter information, and policy information. Disclosed techniques also include rapid determination of expired objects and associated storage resources. Disclosed techniques may advantageously provide a centralized view across buckets, accounts, and regions and allow users to target specific subsets of their data stores for backup, which may improve performance and reduce backup storage costs, relative to traditional techniques.

Abstract: Techniques are disclosed relating to providing object-level incremental backups and data restoration management techniques in a cloud-based backup storage context. In various embodiments, the disclosed techniques include generating, by a computing system, object-level differentials that maintain differences between successive inventories (e.g., added, deleted, and amended objects) and are used to perform incremental backups. Disclosed techniques also include restoration management methods that leverage parallelization, via chunks of data that may be processed in parallel by cloud worker modules, and protection group mechanisms to restore single buckets, multiple buckets, single objects, multiple objects, objects and buckets that match specific search criteria, etc. Disclosed techniques may advantageously improve performance of data backup and restoration operations, relative to traditional techniques.
