Abstract: In various embodiments, an archival agent of a database tracks database records stored in a primary storage of a cloud-based storage system to identify particular database records that are relevant to a current state of the database. A replication service of the cloud-based storage system replicates database records from the primary storage to an archival storage that includes database records of the database that are no longer relevant to the current state of database. The archival agent records identifiers of the particular relevant database records in a manifest file associated with the current state of the database and provides the manifest file to the replication service for storage in the archival storage. In response to a failure associated with the primary storage, the database can be recovered to its current state using the identifiers recorded in the stored manifest file to determine what database records to read.

Abstract: Techniques are disclosed relating to archive operations for database systems. In some embodiments, a database system initiates one or more archive operations to archive one or more data extents for a database maintained by the database system. The system may halt archive activity for the database, in response to determining that archive operations for a threshold amount of data extents are initiated but not completed. The system may cancel at least one of the one or more archive operations. The system may determine to resume activity for the database based on determining that a threshold timer interval has elapsed and determining that a threshold amount of storage space is available for the database system. Disclosed embodiments may improve database availability, relative to traditional techniques.
