Abstract: A portion of contents of a database is received from a first server. The received contents of the database is stored in a secondary storage system that tracks changes between different backup versions of contents of the database. A request to migrate the contents of the database to a second server is received. A version of contents of the database is provided to the second server using the secondary storage system. The secondary storage system is configured to determine an amount of changes to the database content from one of the versions of the database content provided to the second server and the amount of changes is utilized in determining whether to quiesce the database hosted on the first server.

Abstract: An indication of a storage service job to be performed is received. A task to be performed for the storage service job is determined. The task is added to a work queue. Execution of one or more tasks in the work queue that includes the task is dynamically managed. Resources are dynamically allocated to one or more virtualization containers that are assigned to execute the one or more tasks in the work queue. An identification of one or more new tasks to be performed for the storage service job is received from one of the virtualization containers executing the task. The one or more new tasks are added to the work queue.

Abstract: A request to migrate from a secondary storage system to a server a requested version of database content of a database backed up at the secondary storage system is received. A new version of the database content at the secondary storage system is instantiated. Functionality of the database is maintained including by allowing a database application hosted on the server to access the database content from the secondary storage system using the instantiated new version of the database content while migrating the requested version of database content from the secondary storage system to the server.

Abstract: A request to store a new value to a data entity to be fault tolerant across a plurality of nodes is received. The data entity being in an intermediate state is indicating to at least one less than a majority of the plurality of nodes. A request to read a stored value of the data entity is received. A latest value instance of the data entity among a majority nodes of the plurality of nodes is determined. A value of the latest value instance in a majority nodes of the plurality of nodes is stored as a next value instance of the data entity.

Abstract: Systems, methods, and computer program products for managing a consensus group in a distributed computing cluster, by determining that an instance of an authority module executing on a first node, of a consensus group of nodes in the distributed computing cluster, has failed; and adding, by an instance of the authority module on a second node of the consensus group, a new node to the consensus group to replace the first node. The new node is a node in the computing cluster that was not a member of the consensus group at the time the instance of the authority module executing on the first node is determined to have failed.

Abstract: Techniques are disclosed for identifying “free” compute nodes that have not been configured as a member of a secondary storage system. As disclosed, a node may automatically detect that it is a free node (i.e., one available to join a distributed computing cluster which provides the secondary storage system or to form a new cluster). When a node detects that it is not part of a cluster, the node may build an initial network configuration and begin advertising itself as a free node. Once the initial network state is available, the node may broadcast advertisements observed by a management tool and joined to the secondary storage system.
