A method and system for backing up data is provided. The method includes storing a first plurality of data units in a backup storage, as a result of a fingerprint database being available, the first plurality of data units being deduplicated through application of the fingerprint database. The method includes storing a second plurality of data units in the backup storage, as a result of the fingerprint database being unavailable, wherein at least one step of the method is executed through a processor.

System and method for operational continuity of backup operations to a deduplicated storage

A hybrid deduplication system operates to detect variable-sized deduplication matches, while performing the storage deduplication on fixed-size segments of data. The hybrid deduplication system calculates unique identifiers for variable-sized sections of data within a data stream being written to a deduplicated data store. The hybrid deduplication system then compares those newly-calculated identifiers to identifiers of variable-sized sections of data that have already been stored within the deduplicated data store. If a match is found, the hybrid deduplication system identifies the location of each of the fixed-size data segment(s), already stored in the deduplicated data store, that include the identified variable-sized section of data. Instead of writing the sections that match already-existing sections to the deduplicated data store, the hybrid deduplication system simply causes the creation of a reference to the identified storage locations, indicating that the data stream being written includes the data in these pre-existing storage locations.

The disclosed computer-implemented method for controlling auxiliary device access to computing devices based on device functionality descriptors may include (i) detecting a connection of an auxiliary device to a client computing device, (ii) receiving a set of functionality descriptors from the auxiliary device, each functionality descriptor of the set of functionality descriptors identifying a separate functionality of the auxiliary device, (iii) determining whether the set of functionality descriptors matches a set of reference descriptors, and (iv) performing a security action based on the determination of whether the set of functionality descriptors matches the set of reference descriptors. Various other methods, systems, and computer-readable media are also disclosed.

A method for backing up data is provided. The method includes deduplicating a first plurality of data units during a backup operation through application of a first deduplication service and a fingerprint database. The method includes logging a second plurality of data units in a journal, during the backup operation. The logging is in response to a failure of the first deduplication service and wherein at least one method operation is executed through a processor.

The disclosed computer-implemented method for scalable network buffer management may include (1) receiving, via a connection to a client, data to be transmitted to a cloud service, (2) buffering the data in at least one data buffer, (3) determining that the data will not be transmitted to the cloud service within a timeout period for the client connection, (4) delaying reception of additional data from the client connection for a portion of the timeout period, and (5) before the timeout period has elapsed, buffering data from the client connection in at least one secondary data buffer, wherein the secondary data buffer is smaller in size than the data buffer. Various other methods, systems, and computer-readable media are also disclosed.

A computer-implemented method for reclaiming storage space in deduplicating data systems may include (1) storing at least one non-synthesized backup image within a deduplicating data system by storing at least one data segment of the non-synthesized backup image within a container of deduplicated data segments that is used by the deduplicating data system, (2) storing at least one synthesized backup image within the deduplicating data system by referencing at least one previously stored data segment within the container that is also referenced by a previous backup image within the deduplicating data system, (3) determining that no non-synthesized backup images still reference the container, and (4) removing the data segment of the non-synthesized backup image from the container of deduplicated data segments in response to determining that no non-synthesized backup images still reference the container. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for reclaiming storage space in deduplicating data systems

A computer-implemented method for preserving deduplication efforts after backup-job failures may include (1) identifying a deduplicated data system that reduces redundant data storage by storing and referencing a plurality of deduplicated data segments and reclaims storage space by deleting unreferenced data segments from the deduplicated data system, (2) identifying a backup job that backs up data to the deduplicated data system, causes the deduplicated data system to store at least one new data segment available to be referenced within the deduplicated data system, and fails after the deduplicated data system stores the new data segment within the deduplicated data system causing the new data segment to be unreferenced within the deduplicated data system, and (3) causing the deduplicated data system to retain the new data segment until the backup job is retried despite the new data segment being unreferenced. Various other methods, systems, and computer-readable media are also disclosed.

A method and apparatus for performing a reputation based analysis on a malicious infection to secure a computer. In one embodiment, the method includes monitoring application activity occurring at computers, generating reputation information associated with the application activity, in response to a malicious infection to at least one of the computers, examining the reputation information to access unreputed portions of the application activity that occurred at the at least one of the computers and determining a malicious signature based on the unreputed portions of the application activity.

Techniques for storage lifecycle policy management. In one particular exemplary embodiment, the techniques may be realized as a method for storage lifecycle policy management comprising creating a version of a storage lifecycle policy, associating a unique version ID with the created version of the storage lifecycle policy, associating the unique version ID with one or more portions of backup data created during a storage management job instantiated under the created version of the storage lifecycle policy, and ensuring that one or more storage management actions performed on the one or more portions of backup data comply with the created version of the storage lifecycle policy associated with unique version ID.

Techniques for storage lifecycle policy management

A method and apparatus for implementing a storage lifecycle policy based on a hierarchy of storage destinations to improve storage lifecycle management is described. In one embodiment, the method comprises specifying at least one source copy for at least one storage lifecycle operation in a storage lifecycle policy to generate a storage destination hierarchy using the at least one specified source copy and performing the at least one storage lifecycle operation using the storage destination hierarchy.
