Abstract: Methods and systems for restoring data are described. According to some embodiments, the method, in response to receiving a first restore request, initiates a second restore request to a hybrid data buffer to route blocks of backup data to the hybrid data buffer. The method further invokes an interrupt service routine (ISR) that is initialized with reserved addresses. When the blocks of backup data are transmitted to the hybrid data buffer, the method further tags, by the ISR, the blocks of backup data to a specified location, where the specified location is one of the reserved addresses.

Abstract: In general, in one aspect, the invention relates to a method for enabling enhanced logging. The method includes obtaining a log associated with a job; determining, using the log, that enhanced logging is to be enabled prior to initiating the job; enabling, in response to the determination, enhanced logging on at least one node, and initiating servicing of the job, after the enabling, on the at least one node.

Abstract: Embodiments are described for performing an uninterrupted backup in a storage system responsive to an abort event. A backup agent receives a plurality of file objects to be backed up on a target device during a first backup session. The backup agent initiates a parent interrupt service routine (ISR), which generates a plurality of child ISRs. Each of the plurality of child ISRs monitors a backup state of a corresponding file object. The parent ISR generates a virtual file object queue (VFOQ) to store a current backup state of each of the plurality of file objects. When an abort occurs, the current backup state of each of the plurality of file objects is saved in a respective child ISR of that file object. During a subsequent backup session, backup of the plurality of file objects commences based on the current backup state of each of the plurality of file objects.

Abstract: A method for managing a data protection module includes: obtaining client metadata of a client environment data protection module (CEDPM); analyzing the client metadata to extract relevant data; inferring at least a period of time a first user of the CEDPM spent to initiate performing a task, a number of steps taken by the first user to initiate performing the task, and a number of attempts made by the first user to initiate performing the task; obtaining at least an ease of use score, an automation efficiency score, and a success score for a product feature; obtaining a maturity rating for the product feature based on the scores; determining that the maturity rating for the product feature is less than a predetermined maturity rating; and sending a recommendation to a second user of a vendor environment (VE) data protection module to manage the maturity rating for the product feature.

Abstract: For restoring data, a system with uninterrupted block-based restore has a hybrid container. The hybrid container has an operational buffer and a virtual container unit. The system receives blocks of data from a target device into the hybrid container and sends the blocks of data from the hybrid container to a destination device for a restore session. The system writes information about the blocks of data into one or more virtual containers. If there is an abort of the restore session, the system freezes state of the hybrid container and the virtual container(s). For a next restore session that resumes from where the aborted restore session stopped, the system resumes receiving blocks of data from the target device into the hybrid container and sends only leftover blocks of data to the destination device in accordance with the information in the virtual container(s).

Abstract: Methods and systems for restoring data to a host device are described. According to some embodiments, a hybrid buffer may be used to generate a twin file of each file object to be restored and append the twin file to the corresponding file object. Each file object and its corresponding twin file may be transmitted to a construction container via a restore agent. In the event of an unexpected abort during the first restoration session, the restore agent may preserve the twin file of a file object currently being restored (if one has been created at the time of the abort) and instruct the hybrid buffer to terminate operation. During a subsequent restore session, the restore agent may poll for the preserved twin file and commence the data restore operation from the file object currently being restored using the twin file.

Abstract: In one example, a method can be performed that involves receiving a backup request specifying: one or more files to be backed up; a group of one or more categories, each of which corresponds to a respective range of file sizes; and, one or more storage destinations, categorizing each of the files by assigning a respective category to each file, initiating a respective backup datastream corresponding to each category that has been assigned, and requesting that each backup datastream be backed up at the respective storage destination that corresponds to the assigned category associated with that backup datastream.

Abstract: A pass-through snapshot engine records lifecycle data and chronological status of files or objects, in one or more pass-through snapshots during a backup. If there is an abort, the pass-through snapshot engine freezes the pass-through snapshot(s) and terminates the backup. To restart after the abort, the pass-through snapshot engine sends one or more pass-through snapshots to the backup agent. The backup agent restarts the backup, and enforces states of lifecycle and chronology to files or objects, and discards files or objects that have already been backed up to the target device, in accordance with the one or more pass-through snapshots.

For each data stream, the method detects a data change within the data stream. The method further determines a magnitude of the data change. The method further assigns a tier level to the data stream based on the magnitude of the data change.

Abstract: An apparatus for performing backup operations for data packets by a backup agent is provided. The apparatus predicts a first backup time period of completing a first backup operation for the data packets and determines a second backup time period of performing the first backup operation until the first backup operation is stopped at a point of time. The apparatus also identifies an incomplete status of the first backup operation at the point of time based on a comparison between the first backup time period and the second backup time period, and collects information describing the incomplete status. The apparatus further starts a second backup operation for the data packets from the incomplete status based on the information.

Abstract: Methods and systems for restoring data from a target device are described. According to some embodiments, the method receives a first set of data packets for restore, where the first set of data packets includes a multiplicity of data chunks. The method further captures footprints of the first set of data packets in a cache disk array. In response to receiving an acknowledgement from the cache disk array indicating the footprints of the first set of data packets have been captured, the method pushes each data chunk of the first set of data packets to a construction container for reconstruction of backup data. In response to receiving an acknowledgement from the construction container indicating the data chunk is successfully pushed, the method flushes the respective footprint of the data chunk from the cache disk array.
