Abstract: A system and method for avoiding duplicate backups of data in a volume backup image. A cluster of nodes is coupled to a data storage medium configured to store data corresponding to a shared volume. A node receives a request for the backup of the shared volume. In response to this request, the node queries all other nodes in the cluster for identification of a subset of the shared volume data that should be excluded from the backup. The identified subset of the data may correspond to at least a file under control of a database application or other particular application. It may be known that this identified subset of the data will be backed up by a subsequent agent-based backup operation after the volume backup. In response to receiving all query responses, the node initiates a backup corresponding to the data in the shared volume excluding the identified subset of the data.

Abstract: Example apparatus and methods concern creating synthetic backups from existing backups. One example method includes accessing first information that is associated with an existing backup(s). The first information may be computer data that describes data stored on a backup media or appliance. The first information may be referred to as metadata. The existing backup may reside on a backup medium (e.g., tape), on a backup appliance (e.g., disk), or elsewhere. The example method includes instantiating second information (e.g., metadata) associated with a synthetic backup to be created. The second information may be stored on a non-transitory computer-readable medium. The example method also includes selectively manipulating the second information to create the synthetic backup. The manipulating may include copying portions of the first information into the second information. In one embodiment, the synthetic backup is only logically created and thus no data is copied from the existing backup.

Abstract: A method of archiving a set of source tables in a database system. Each source table has a plurality of rows. Initially, a consistency point for the set of source tables is established. The database system creates a log record for each change (insert, modify, or delete) effected to a row of the source tables subsequent to the consistency point. Substantially all source table rows are copied to an archive (a data storage object that is external to the database system). Then the accumulated log records for the affected source tables are distilled and appended to the archive.

Abstract: A method for using a change-recording feature to perform more effective backups includes generating an initial point-in-time copy of source data residing in a storage device. The method may then perform an initial backup of the initial point-in-time copy. As changes are made to the source data, the method may record changes made to the source data after the initial point-in-time copy is generated. These changes may be stored as incremental change data. At some point, the initial point-in-time copy may be updated using the incremental change data. In order to perform an incremental backup of the updated point-in-time copy, the method may query the incremental change data to determine which changes were used to update the point-in-time copy. The method may then perform an incremental backup of the updated point-in-time copy by backing up the changes designated in the incremental change data.

Abstract: An incremental backup service may be configured to backup structured files and unstructured files on a client system. A filter driver 130 may be configured to monitor write operations on the client system and log changed cluster address information for structured files. The backup service may backup changed clusters of structured files to a backup storage device. For each of the unstructured files, the backup service may compare the file size to a threshold size. If the unstructured file is smaller than the threshold size, the backup service may backup the entire unstructured file. If the file size is larger than the threshold size, the backup service may determine the ratio of changed clusters to unchanged clusters. If the ratio is below a ratio threshold, the backup service may backup the changed clusters. If the ratio is above the ratio threshold, the backup service may backup the entire file.

Abstract: Described herein are systems and methods for multiplexing pipelined data for backup operations. Various data streams are combined such as by multiplexing by a multiplexing module. The multiplexing module combines the data from the various data streams received by receiver module(s) into a single stream of chunks. The multiplexing module may combine data from multiple archive files into a single chunk. Additional modules perform other operations on the chunks of data to be transported such as encryption, compression, etc. The data chunks are transmitted via a transport channel to a receive pipeline that includes a second receiver module and other modules. The data chunks are then stored in a backup medium. The chunks are later retrieved and separated such as by demultiplexing for restoring to a client or for further storage as auxiliary copies of the separated data streams or archive files.

Abstract: A system for storing encrypted data comprises a processor and a memory. The processor is configured to receive an encrypted segment.

Abstract: A method and system is provided for copying data between two deduplicating storage systems. A list of unique fingerprints is compiled from the data which will be sent. This list is transmitted to the receiving system during a preliminary data exchange called the preamble. The receiving system replies with a second list which contains the unique fingerprints of the data which either needs to be sent or can be omitted. Which list depends on the size of the list where the smaller list is sent for efficiency and lower bandwidth consumption. A reference list of duplicate blocks being sent is retained on the receiving system until the copy operation is complete. This reference list is used to protect blocks on the receiving system by deferring deletions until the incoming hallow block can reference the duplicate block on the receiver to confirm that is on the target system and should not be deleted.

Abstract: A hash-optimized backup system and method takes data blocks and generates a probabilistically unique digital fingerprint of the content of each data block using a substantially collision-free algorithm. The process compares the generated fingerprint to a database of stored fingerprints and, if the generated fingerprint matches a stored fingerprint, the data block is determined to already have been backed up, and therefore does not need to be backed up again. Only if the generated fingerprint does not match a stored fingerprint is the data block backed up, at which point the generated fingerprint is added to the database of stored fingerprints. Because the algorithm is substantially collision-free, there is no need to compare actual data content if there is a hash-value match. The process can also be used to audit software license compliance, inventory software, and detect computer-file tampering such as viruses and malware.

Abstract: A technique for restoring file systems by applying full and incremental backups together while streaming them from multiple devices provides a faster system restore from a full backup where incremental backups must also be applied. A first storage device streams the full backup while at least one second storage device streams at least one incremental backup.

Abstract: A cluster manager is configured to manage a plurality of copies of a mid-tier database as a mid-tier database cluster. The cluster manager may concurrently manage a backend database system. The cluster manager is configured to monitor for and react to failures of mid-tier database nodes. The cluster manager may react to a mid-tier database failure by, for example, assigning a new active node, creating a new standby node, creating new copies of the mid-tier databases, implementing new replication or backup schemes, reassigning the node's virtual address to another node, or relocating applications that were directly linked to the mid-tier database to another host. Each node or an associated agent may configure the cluster manager to behave in this fashion during initialization, based on common cluster configuration information. Each copy of the mid-tier database may be, for example, a memory resident database. Thus, a node must reload the entire database into memory to recover a copy of the database.

Abstract: A deduplication storage system enables new input data to be deduplicated with data of synthetic backups already constructed, and for this purpose efficiently calculates deduplication digests for synthetic backups being constructed, based on already existing digests of data referenced by the synthetic backups. For each input data segment of the plurality of input data segments of a synthetic backup being constructed, a plurality of deduplication digests of stored data segments, referenced by the input data segment, is retrieved from an index. Each input data segment is partitioned into each of a plurality of fixed-sized data sub-segments. A calculation is performed producing a deduplication digest for a data sub-segment, where the calculation is based on the retrieved deduplication digests of the plurality of stored data sub-segments referenced by the input data sub-segment.

In further embodiments, one or more of the segments that have changed may be obtained locally from other files, thus further reducing the amount of data transferred across the network.

Abstract: An archival storage cluster of preferably symmetric nodes includes a metadata management system that organizes and provides access to given metadata, preferably in the form of metadata objects. Each metadata object may have a unique name, and metadata objects are organized into regions. Preferably, a region is selected by hashing one or more object attributes (e.g., the object's name) and extracting a given number of bits of the resulting hash value. The number of bits may be controlled by a configuration parameter. Each region is stored redundantly. A region comprises a set of region copies. In particular, there is one authoritative copy of the region, and zero or more backup copies. The number of backup copies may be controlled by a configuration parameter. Region copies are distributed across the nodes of the cluster so as to balance the number of authoritative region copies per node, as well as the number of total region copies per node.

Abstract: A server auditing process that stores only a single up-to-date data record along with the differences relative to previous changes in the record that allow the user to move “backward in time” to recreate previous values. The auditing feature introduces a baseline database table and a difference database table for each existing database table. The baseline table stores the most recent auditing data and the differences table complements the baseline table by storing pairs in the form of attribute name and previous value. By applying difference rows to baseline data, the user is able to recreate the data as it existed at any given timestamp and at a minimal storage cost. The architecture minimizes the impact of auditing on system performance by employing an asynchronous priority queue so that task processing is deferred until the system has adequate resources and other work is not affected.
