Abstract: A system and method is disclosed for performing a backup of electronic data. An example method includes storing a first incremental data backup of a dataset that is less than a complete backup of the dataset and includes unmodified and modified portions of the dataset. Then, a second incremental data backup of the dataset is stored that includes a second unmodified portion of the dataset different than the first unmodified portion. The method then determines whether the first and second incremental data backups together form the complete backup of the dataset. If they do not, the method further stores a subsequent incremental data backup of the dataset in the electronic memory that includes an additional unmodified portion of the dataset and/or an additional modified portion of the dataset.

Abstract: Disclosed are systems and methods for data archiving using machine learning techniques. The system collects statistical information and event data and processes them using machine learning techniques to classify data and/or predict data access demands. The system receives statistical information related to user access of a plurality of files, which can effectively “train” the system to archive data that is not needed at a certain moment and extract it at other moments. The system identifies, using a machine learning module, a pattern of access in the plurality of files based on the received statistical information. The system modifies, using the identified pattern of access, a threshold value related to file access, and assigns a set of files from the plurality of files an access classification based on the modified threshold value. The system migrates the set of files between hot and cold data areas based on the assigned access classification.

Abstract: A method for optimizing lock detection in a change block tracker (CBT). A volume subject to the backup constantly receives writes. Therefore, it is important to divide writes that occurred before the lock and the write that occurred after the lock. The CBT is installed into kernel at the installation of the backup agent (application). The detection of changes is started at the completion of a previous snapshot. Snapshot creation request (SCR) is generated. Lock request is received by the CBT. Once the lock request is intercepted, the current changes are moved to frozen changes. The CBT processes the SCR and creates a collection of changes—i.e., snapshot with a Name. The CBT moves the current changes to the snapshot Name.

Abstract: The present disclosure relates to systems and methods for archiving and restoring data. An exemplary method comprises receiving a request to archive, at a data center, an encrypted data object stored on a remote computing node, determining whether at least one of a copy of the encrypted data object or a similar data object exists in an archive of encrypted data objects stored at the data center, when a copy of the encrypted data object is found, generating a reference to the copy of the encrypted data object and archiving the reference in the archive as a proxy for the encrypted data object. When a similar data object is found, the method generates a reference to the similar data object, identifies information unique to the encrypted data object by comparing the encrypted data object and the similar data object; and archives both the reference to the similar data object and the unique information as a proxy for the encrypted data object.

Abstract: A data backup application checks validity of data being backed up during an incremental or a full backup. In case of the file backup, the full backup checks the validity of data during the backup, because in case of data corruption the user will not have any original data since no data has been backed up yet. In case of the incremental backup, only the new files or the files that have changed compared to the last backup are now backed up. All new and modified files can be checked for validity by comparing internal format of the user files against a corresponding file format standard. If corrupted files are detected among the modified files, the user is notified.

Abstract: A system and method provided for managing services and licenses using blockchain technology. An exemplary method includes storing an operator license relating to an operator node associated with a vendor, where the operator license indicates transactional authority of the operator node. Moreover, the method includes executing a transaction relating to a service and/or a license provided to client device; transmitting data relating to the operator license to a blockchain network in which a node in the blockchain network adds the data relating to the operator license as one or more blocks in an existing blockchain; and replicating the transaction to at least one additional node in the blockchain network. As a result, the existing blockchain can be used to verify the transaction authority of the operator node and the transaction between the client device and the operator node.
