| 20100211547 | File sharing system, file server, and method for managing files - In the HSM function, when supporting the file system snapshot function, a differential data volume is required for both a high-speed volume and a low-speed volume. Accordingly, when supporting the snapshot function by using a file system provided by the HSM function, a large amount of differential data volume is required. When the manager gives an instruction to acquire a snapshot, a snapshot management program executes snapshot acquisition processing to acquire a snapshot. In this processing, a snapshot reference relation building processing part copies a file storage location management table, and relates the file storage location management table to the acquired snapshot. Then, the snapshot reference relation building processing part checks a file that is migrated to a file system which does not have a differential data volume. Finally, the snapshot reference relation building processing part creates a link of the migrated file to the snapshot which is acquired previous time. | 08-19-2010 |
| 20100241614 | DEVICE AND METHOD FOR ENABLING LONG-LIVED SNAPSHOTS - Decreasing disk costs make it possible to take frequent snapshots of past storage system states and retain them for a long duration. Existing snapshot approaches offer no satisfactory solution to long-lived snapshots. Split snapshots are an approach that is promising because it does not disrupt the current state storage system in either the short or the long run. An unsolved problem has been how to maintain an efficient access method for long-lived split snapshots without imposing undesirable overhead on the storage system. Skippy is a new approach that inexpensively indexes long-lived snapshots in parallel with snapshot creation. An embodiment of Skippy uses append-only index data structures to optimize writes while simultaneously providing low-latency snapshot lookup. Performance evaluations of Skippy indicate that this new approach is effective and efficient. It provides close-to-optimal access to long-lived snapshots while incurring a minimal impact on the current-state storage system. | 09-23-2010 |

Instead, the original physical file unit of data in the storage is preserved and the original reference pointer for the original physical file unit of data may be used to map a new logical file unit in the file system to the original physical file unit storing the original set of data. Other aspects are described. | 11-19-2015 |
| 20150347430 | TECHNIQUES FOR ENABLING COARSE-GRAINED VOLUME SNAPSHOTS FOR VIRTUAL MACHINE BACKUP AND RESTORE - A technique of backing up a workload in a virtual environment includes identifying one or more files that are associated with the workload. One or more source volumes that include the one or more files are identified. A respective target volume is provisioned for each of the one or more source volumes identified. Only dirty blocks are copied (in a snapshot mode that prevents an update to the one or more source volumes during the snapshot mode) from each of the one or more source volumes to its respective target volume. The one or more dirty blocks are then copied from each target volume to a backup medium. | 12-03-2015 |
| 20160004721 | REPLICATING LOCAL FILE SYSTEMS AS RESPECTIVE LUNS IN A STORAGE ARRAY, USING BLOCK-LEVEL DATA TRANSFERS AND ENHANCED STORAGE MANAGERS, DATA AGENTS, AND MEDIA AGENTS IN AN INFORMATION MANAGEMENT SYSTEM - Systems and methods are disclosed for block-level incremental replication of a local file system in a source volume/partition to a storage array—replicated to a single logical disk designated by a logical unit number (LUN) with a single volume/partition corresponding to the source. From the perspective of the storage array, non-native data (e.g., data in a local file system residing in locally-attached storage) may be backed up to a LUN that is native to the storage array and thus available for any number of subsequent LUN-based operations. Enhanced data agents, media agents, and storage manager(s), including replication storage policies, operate in concert with the storage array to execute successive file-system-to-LUN block-level replication jobs to protect the data in the local file system. | 01-07-2016 |

| 20160019317 | VOLUME OR VIRTUAL MACHINE LEVEL BACKUP AND GENERATING PLACEHOLDERS FOR VIRTUAL MACHINE FILES - According to certain aspects, a method can include creating a backup copy of data associated with a virtual machine (VM) on one or more secondary storage devices, wherein the backup copy includes corresponding secondary copies of a plurality of files associated with the VM; analyzing metadata associated with the secondary copies to determine which of the plurality files are eligible to be removed from the primary storage device; in response determining that one or more files are eligible to be removed from the primary storage device, for respective file of the one or more files: determining whether the respective file has been changed since a first time at which the backup copy of the data associated with the VM was created; in response to determining that the respective file has not changed since the first time, removing the respective file; and adding a file placeholder for the removed file. | 01-21-2016 |
| 20160034356 | BACKUP OPERATIONS IN A TREE-BASED DISTRIBUTED FILE SYSTEM - Techniques for cloning, writing to, and reading from file system metadata. Cloning involves identifying a first set of pointers included in a first root node in a file system metadata tree structure that stores file system metadata in leaf nodes of the tree structure, creating a first copy of the first root node that includes the first set of pointers, creating a second copy of the first root node that includes the first set of pointers, associating the first copy with a first view, and associating the second copy with a second view. Reading generally involves traversing the tree structure towards a target leaf node that contains data to be read. Writing generally involves traversing the tree structure in the same manner, but also creating copies of any nodes to be modified if those nodes are deemed to have a different treelD than a particular root node. | 02-04-2016 |
| 20160042090 | PRESERVING THE INTEGRITY OF A SNAPSHOT ON A STORAGE DEVICE VIA EPHEMERAL WRITE OPERATIONS IN AN INFORMATION MANAGEMENT SYSTEM - A pseudo-storage-device driver is employed to configure pseudo-volumes that correspond to respective snapshots in a storage array. Each pseudo-volume is mounted as a recovery point instead of the corresponding snapshot. Instead of writing changes to the snapshots, the changes—typically modifications to metadata associated with the snapshot—are managed via the pseudo-volume. Metadata changes that arise in the context of mapping, mounting, and/or using a snapshot are written to the pseudo-volume, in a data structure referred to as a “private store.” Information management operations that need metadata associated with the snapshot are directed to the private store for the latest updates to the metadata. After the information management operation ends, the pseudo-volumes are unmounted and the updates in the private store are discarded. Because no changes were made to the snapshot, no changes need to be reversed. Accordingly, the illustrative system preserves the integrity of the snapshots through any number of information management operations that may generate metadata changes. Moreover, because the illustrative system is agnostic as to whether a given storage device is persistent-type or not, there is less burden on administration and also less risk of error. | 02-11-2016 |
| 20160048429 | Back-Up Storage For Home Network - An embodiment of the present invention is a technique to provide back-up storage.

The device is configured to receive a file using the information. The file is transferred to the device. | 02-18-2016 |
| 20160062846 | CONSOLIDATED PROCESSING OF STORAGE-ARRAY COMMANDS USING A FORWARDER MEDIA AGENT IN CONJUNCTION WITH A SNAPSHOT-CONTROL MEDIA AGENT - The illustrative systems and methods consolidate storage-array command channels into a media agent that executes outside the production environment. A “snapshot-control media agent” (“snap-MA”) is configured on a secondary storage computing device that operates apart from client computing devices. A “forwarder” media agent operates on each client computing device that uses the storage array, yet lacks command channels to the storage array. Likewise, a “forwarder” proxy media agent may operate without command channels to the storage array. No third-party libraries or storage-array-command devices are installed or needed on the host computing device. The forwarder media agent forwards any commands directed at the storage array to the snap-MA on the secondary storage computing device. The snap-MA receives and processes commands directed at the storage array that were forwarded by the forwarder media agents. Responses from the storage array are transmitted to the respective forwarder media agent. The snap-MA advantageously pools any number of storage-array-command devices so that capacity limitations in regard to communications channels at the storage array may be avoided. As a result, the snap-MA operating in conjunction with the forwarder media agents enable the illustrative system to consolidate the communication of storage-array commands away from client computing devices and/or proxy media agent hosts and into the secondary storage computing device that hosts the snap-MA. | 03-03-2016 |
| 20160063014 | METHODS AND SYSTEMS FOR CREATING AND REMOVING VIRTUAL MACHINE SNAPSHOTS BASED ON GROUPS OF METRICS - Techniques are described herein which minimize the impact of virtual machine snapshots on the performance virtual machines and hypervisors. In the context of a volume snapshot which may involve (i) taking virtual machine snapshots of all virtual machines associated with the volume, (ii) taking the volume snapshot, and (iii) removing all the virtual machine snapshots, the virtual machine snapshots may be created in a first order and removed in a second order. Specifically, snapshots for busy virtual machines (i.e., virtual machines with higher disk write activity) may be created last and removed first. Consequently, snapshots of busy virtual machines are retained for the shorter periods of time, thereby minimizing the effect of virtual machine snapshots on those virtual machines (and their associated hypervisors) that would be most negatively impacted by virtual machine snapshots. | 03-03-2016 |
| 20160077920 | SNAPSHOTS AND FORKS OF STORAGE SYSTEMS USING DISTRIBUTED CONSISTENT DATABASES IMPLEMENTED WITHIN AN OBJECT STORE - A method is described that includes providing a snapshot counter for a storage system implemented with multiple distributed consistent database instances. The method further includes recognizing the taking of a snapshot of the storage system by incrementing the snapshot counter from a first snapshot counter value to a second snapshot counter value. The method further includes, in response to a first change for one of the distributed consistent databases subsequent to the taking of the snapshot, performing the following: saving state information of the distributed consistent database as the state information existed prior to the change and associating the first snapshot counter value to the state information. Associating the second snapshot counter's value with the distributed consistent database having the first change. Another method for the taking of a snapshot of a distributed consistent database is also described. | 03-17-2016 |
| 20160078044 | MAIN-MEMORY DATABASE CHECKPOINTING - The present invention extends to methods, systems, and computer program products for main-memory database checkpointing. Embodiments of the invention use a transaction log as an interface between online threads and a checkpoint subsystem. Using the transaction log as an interface reduces synchronization overhead between threads and the checkpoint subsystem. Transactions can be assigned to files and storage space can be reserved in a lock free manner to reduce overhead of checkpointing online transactions. Meta-data independent data files and delta files can be collapsed and merged to reduce storage overhead. Checkpoints can be updated incrementally such that changes made since the last checkpoint (and not all data) are flushed to disk. Checkpoint I/O is sequential, helping ensure higher performance of physical I/O layers. During recovery checkpoint files can be loaded into memory in parallel for multiple devices. | 03-17-2016 |

| 20160140253 | Platform for Continuous Graph Update and Computation - A continuous stream data (e.g., messages, tweets) is received by ingest nodes of a platform. The ingest nodes may analyze the data to create a transaction of graph updates, assign a sequence number to the transaction, and distribute the graph updates with the sequence number to graph nodes of the platform. The graph nodes may store graph updates from ingest nodes, and then the ingest nodes may report graph update progresses in a progress table. A snapshot may be taken based on the progress table, and then graph-mining computation may be implemented. Tolerate failures and decaying may be supported and incremental expansion may be allowed to cope with increasing update rates and computation needs. | 05-19-2016 |
