A determination is made that a backup of a database in an availability group provided by a relational database management system (RDBMS) should be performed. The availability group includes a node functioning as a primary node and hosting a primary replica of the database and one or more other nodes functioning as secondary nodes and hosting secondary replicas of the database. The availability group is a clusterless availability group in which the one or more other nodes functioning as secondary nodes are not available as automatic failover targets should the primary node become unavailable. A command is issued to a node in the availability group to obtain a globally unique identifier (GUID) of the availability group. The node is instructed to index a backup of the database against the GUID of the availability group.

Protecting databases in a clusterless availability group

One example method includes performing data protection operations including backup operations. Backups of an availability group include a full backup, transaction log backups, and differential backups. Each differential backup includes transactions since the full backup. The differential backups are performed based on a trigger and, during a restore operation, the differential backups reduce the number of restores that need to be performed and can be restored instead of restoring the corresponding transactional log backups.

Smart automation of reliable differential backups of always on availability group databases to optimize the restore time

A backup storage includes a persistent storage and a backup manager. The persistent storage stores backups of entities and a global application data map. The backup manager obtains a restoration request for restoration of an application hosted by an entity of the entities; makes a determination to accelerate the restoration based, at least in part, on the application; in response to the determination: identifies a virtual disk level backup of the entity that is associated with the application using the global application data map; obtains the virtual disk level backup from the backups of the entities; and restores the application using the virtual disk level backup.

System and method for accelerated data access

A backup storage includes persistent storage and a backup manager. The persistent storage stores backups of entities and an entity list that lists the entities. The backup manager obtains a restoration availability request from a user; filters the entity list based on an identity of the user to obtain an available entity list; identifies, based on user input obtain based on the available entity list, an entity of the entities; and restores the entity using the backups.

System and method for limiting restoration access

A backup storage includes a persistent storage and a backup manager. The persistent storage stores virtual machine level backups and application level backups. The backup manager obtains a request for a point in time restoration of an application; identifies, based on the application, a virtual machine level backup of the virtual machine level backups that is associated with: a virtual machine that hosted an instance of the application and a first point in time prior to a restoration point in time specified by the request for the point in time restoration; identifies, based on the application, an application level backup of the application level backups that is associated with the restoration point in time; generates a point in time backup using: the identified virtual machine level backup, and the identified application level backup; and services the request using the point in time backup.
