Abstract: A system and method for transferring data in a library storage system. The library storage system comprises a management server including a storage policy. A media agent is connected to the management server. A plurality of storage media and a data source are connected to the media agent. The data source is divided into at least a first and a second portion of data. The portions of data are transferred from the data source to a first and second primary storage medium using a first and a second data stream respectively. The media agent then causes the first and second portion of data to be transferred from the first and second storage medium to a third auxiliary storage medium using a third combined data stream. Auxiliary copying is performed in chunks and multiple streams are copied in parallel.

Abstract: A distributed data warehouse system maintains data blocks on behalf of clients, and stores primary and secondary copies of data blocks on different disks or nodes in a cluster. The data warehouse system may back up data blocks in a key-value backup storage system. In response to a query targeting a data block previously stored in the cluster, the data warehouse system may determine whether a consistent, uncorrupted copy of the data block is available in the cluster (e.g., by applying a consistency check). If not (e.g., if a disk or node failed), the data warehouse system may automatically initiate an operation to restore the data block from the backup storage system, using a unique identifier of the data block to access a backup copy. The target data may be returned in a query response prior to restoring primary and secondary copies of the data block in the cluster.

Abstract: A distributed data warehouse system may maintain data blocks on behalf of clients in multiple clusters in a data store. Each cluster may include a single leader node and multiple compute nodes, each including multiple disks storing data. The warehouse system may store primary and secondary copies of each data block on different disks or nodes in a cluster. Each node may include a data structure that maintains metadata about each data block stored on the node, including its unique identifier. The warehouse system may back up data blocks in a remote key-value backup storage system with high durability. A streaming restore operation may be used to retrieve data blocks from backup storage using their unique identifiers as keys. The warehouse system may service incoming queries (and may satisfy some queries by retrieving data from backup storage on an as-needed basis) prior to completion of the restore operation.

Abstract: A distributed data warehouse system may maintain data blocks on behalf of clients, and may store primary and secondary copies of each data block on different disks or nodes in a cluster. The warehouse system may back up data blocks in a remote key-value backup storage system. A restore operation may retrieve data blocks from backup storage using their unique identifiers as keys (while incoming queries are serviced) in response to a failure or a query targeting data that was lost or corrupted. The order in which data blocks are restored may be dependent on the relative likelihood that they will be accessed in the near future (e.g., based on how recently or frequently they were accessed, written, or backed up; the values of one or more access counters associated with each data block; or how recently a database table containing data in each data block was loaded).

Abstract: An “operate with missing region” feature of this disclosure allows the cluster to continue servicing reads for available regions even when some regions are missing. In particular, upon a given node failure condition, the cluster is placed in an effective read-only mode for all regions. The node failure condition typically is one where there has been a failure of an authoritative region copy and no backup copy is then available. As used herein, “read-only” means that no client write or update requests will succeed while the cluster is in this state. In particular, those requests should fail with an error message (or the like) that indicates failure because of the read-only status. Preferably, such requests are then re-tried. In this mode, all regions are only allowed to perform read operations. During the read-only state, the cluster continues to operate with missing regions, and missing regions are entered on the region map.
