Abstract: Techniques for accelerating data movement from a source storage system to a target storage system are described herein. According to one embodiment, a first data stream is received to be transmitted to a remote storage system over a network, the first data stream having multiple data objects, each identified by a data object identifier (ID). A difference is determined between the first data stream and a second data stream that has been previously transmitted to the remote storage system, including identifying one or more data objects that are added, deleted, and/or modified. Differential object information is transmitted to the target storage representing the difference between the first data stream and the second data stream, as well as one or more data objects that are missing in the second data stream without having to transmit all data objects of the first data stream.

Abstract: A cluster network environment may comprise a plurality of nodes configured to perform various tasks, such as data I/O, storage, backup, etc. It may be advantageous to improve disaster recovery and reliability by creating backups that may be used to restore the cluster network environment and/or nodes therein. Accordingly, one or more techniques and/or systems are disclosed for restoring a cluster network environment and/or nodes therein. In particular, cluster configuration data, which may be stored in a healthy node or at a remote source, may be used to restore a node affected by an integrity loss. If the integrity loss affects the cluster network environment (e.g., a majority of healthy nodes are lost), then a new cluster network environment may be created from a healthy node or a restored healthy node. The creation of the new cluster network environment may be based at least in part on cluster configuration data.

Abstract: A method for replicating I/O performance in data replication environments, such as PPRC environments, is described. In selected embodiments, such a method includes monitoring I/O workload at a primary storage device over a period of time, such as a period of hours, days, or months. The method then generates learning data at the primary storage device describing the I/O workload over the selected time period. The learning data is replicated from the primary storage device to a secondary storage device. The method uses the learning data to optimize the secondary storage device to handle the I/O workload of the primary storage device. This will enable the secondary storage device to provide substantially the same I/O performance as the primary storage device in the event a failover occurs. A corresponding system and computer program product are also disclosed and claimed herein.

Abstract: As described herein, a high-availability server system includes at least a source server system and a target server system that dynamically restore message object search indexes. Both the source server system and the target server system store copies of a mailbox database and a search index for the mailbox database. As changes are requested to the mailbox database, events are added to event lists maintained at the source node and the target node. When the data storage system at the target server system enters an error state, the source server system sends to the target server system a set of data that the target server system can use to generate a copy of search index. The target server system may then resume applying events in the event list to the search index. In this way, it may not be necessary to completely re-index the mailbox database at the target node.

Abstract: A method and system for generating and restoring a backup image are disclosed. According to one aspect of the invention, a server receives a request to generate a backup image. The request includes a selection a backup path. Based on the backup path, the server generates a list of files and/or directories to backup. However, before writing the files to the backup image, the server generates an offset map to indicate where in the backup image each file will be located. The server then writes the offset map to the backup image. During a restore operation, the server receives a request to restore files, including a selection of files and/or directories to restore. The server reads the offset map from the beginning of the backup image to quickly determine the location in the backup image of selected files.

Abstract: A system and method provides continuous data protection using checkpoints in a write anywhere file system. During a consistency point of a write anywhere file system, freed blocks are identified and are appended to a delete log for retention.
