Abstract: An identification of a new primary snapshot created for a primary storage system is received. A change tracking time window that is at least a portion of a period between a first capture time associated with a previous primary snapshot and a second capture time associated with the new primary snapshot is determined. Entries of a storage log of the primary storage system occurring within the change tracking time window are analyzed to coalesce changes identified in the entries of the storage log occurring within the change tracking time window into a change tracking result set. The change tracking result set is used to identify at least a portion of data changes between the previous primary snapshot and the new primary snapshot to capture in a new backup snapshot stored at a secondary storage system.

Abstract: An identification of a new primary snapshot created for a primary storage system is received. A threshold time window based on a capture time associated with the new primary snapshot is determined. Entries of a storage log of the primary storage system occurring within the threshold time window are analyzed to identify any objects of the primary storage system that have changed during the threshold time window. Changed objects to capture in a new secondary backup stored at a secondary storage system and corresponding to the new primary snapshot are identified. Metadata of the new primary snapshot and metadata of a previous secondary backup are compared to determine for each of the objects of the primary storage system identified as having changed during the threshold time window whether a change to an object since the previous secondary backup is captured in the new primary snapshot.

Abstract: A system and method for maximizing network throughput by dynamically tuning the number of connections used during data transfer with various cloud providers. This adaptive tuning of the network connections is based on the accepted request rate for the cloud provider, the outstanding transfer capacity of the cloud network as derived from the network bandwidth, and errors and retry requests from the network and the cloud provider.

Abstract: A method, article of manufacture, and apparatus for performing backup operations using a deduplicated storage system is presented. A data segment can be received at a deduplicated storage system. A fingerprint can be calculated for the data segment. The fingerprint and the offset can be stored in a reference cache on the deduplicated storage system. A metadata segment can be loaded from the deduplicated storage system. The metadata segment can be updated to include the fingerprint. Backup operations may include storage and management using a tree structure.

Abstract: A method, article of manufacture, and apparatus for backup operations. A read request is received for a data segment at a deduplicated storage system. The data segment is determined not to be in a data cache on the deduplicated storage system. A data segment reference for the data segment is determined to be in a data segment reference cache on the deduplicated storage system. The data segment is read from a persistent storage using the data segment reference.

Abstract: Various systems and methods for automated error recovery in workflows. For example, one method involves receiving an operation indication. The operation indication indicates an operation that is to be performed using a multi-tier application system that includes first and second applications. The first and second applications are implemented using different tiers of the multi-tier application system. The method involves accessing dependency information that indicates first data dependencies between the first and the second applications. The method further involves determining outcome of execution of the operation, where the determining is based on the dependency information but does not include executing the operation.

Abstract: A computer-implemented method for disaster recovery of multi-tier applications may include 1) identifying a multi-tier application that is provisioned with a plurality of production clusters at a production site, 2) identifying a disaster recovery site including a plurality of recovery clusters, 3) identifying, at the disaster recovery site, a failure of the multi-tier application at the production site, and 4) initiating, from the disaster recovery site, a migration of the multi-tier application from the production site to the disaster recovery site. Various other methods, systems, and computer-readable media are also disclosed.
