Abstract: A technique for data sharing among multiple filers that share a volume in a private or public cloud object store is implemented. In this approach, a mechanism is provided to enable a local filer to determine whether other filers that are sharing the volume have a consistent view of new data being written to the cloud object store by the local filer. The begins by associating together a collection of one or more files in a “push class.” On demand, a push operation for the push class is initiated on the local filer. Preferably, the push is managed according to one or more push criteria associated with the push class. Typically, the push operation pushes file data and metadata associated with the one or more files of the push class in respective phases, with the file data being pushed to the cloud during a first phase and the metadata associated with that file data being pushed during a second phase that follows the first phase.

Abstract: Methods and systems for storing and managing large numbers of small files. A data processing system includes clients that generate large numbers be stored on a storage device managed by a File System (FS). An Archive Server (AS) receives multiple files from the client, archives the files in larger archives, and sends the archives to the FS for storage. When requested to read a file, the AS retrieves the archive in which the file is stored, extracts the file and sends it to the requesting client. In other words, the AS communicates with the clients in individual file units, and with the storage device in archive units. The AS is typically constructed as an add-on layer on top of a conventional FS, which enables the FS to handle small files efficiently without modification.

Abstract: A data storage system operates to shrink an intermediate logical volume and lower file system upon deletion of a first upper data unit of an upper file system without moving file data on the physical storage devices. Initially, a second upper data unit of the upper file system is identified that is mapped to an end location of the intermediate logical volume. Within the lower file system, a non-end location of the volume file is re-mapped to a first location on the physical storage devices where the data of the end location of the intermediate logical volume is stored. Within the upper file system, the second upper data unit is re-mapped to the non-end location of the intermediate logical volume. Subsequently, the intermediate volume is truncated by removing the portion at the non-end location.

Abstract: A data analysis system is proposed for providing fine-grained low latency access to high volume input data from possibly multiple heterogeneous input data sources. The input data is parsed, optionally transformed, indexed, and stored in a horizontally-scalable key-value data repository where it may be accessed using low latency searches. The input data may be compressed into blocks before being stored to minimize storage requirements. The results of searches present input data in its original form. The input data may include access logs, call data records (CDRs), e-mail messages, etc. The system allows a data analyst to efficiently identify information of interest in a very large dynamic data set up to multiple petabytes in size. Once information of interest has been identified, that subset of the large data set can be imported into a dedicated or specialized data analysis system for an additional in-depth investigation and contextual analysis.

Abstract: Described is a system and method that provides a mechanism for retrieving data from a storage system using one or more techniques. These techniques may be used in a storage configuration that stores backup or recovery data that may be retrieved by an application agent (e.g. intermediary service) in response to a query from a first device (e.g. client device). When data is stored as backup or recovery data, configurations often employ more cost effective (e.g. lower performance) storage solutions. Accordingly, in order to improve retrieval performance, the system may efficiently cache data. For example, the system may store search data from previous queries in a cache associated with the application agent (e.g. local storage) such that subsequent queries may be fulfilled, at least partially, by searching the cached search data instead of the data residing on the remote backup or recovery storage system.

Abstract: One or more techniques and/or computing devices are provided for implementing synchronous replication.

Data file operations may be implemented in parallel upon the local storage and the remote storage. Independent metadata file operations may be independently implemented from data file operations upon the local storage, and upon local completion may be remotely implemented upon the remote storage. In-flight data file operations may be drained before dependent metadata file operations are locally implemented upon the local storage, and upon local completion may be remotely implemented upon the remote storage.

A data-migration orchestration system represents a hierarchical organization of each dataset to be migrated as a tree, where each leaf node of the tree represents data to be migrated and where a path between the leaf node and the root node represents a hierarchical directory pathname of sensitive data represented by the leaf node.

The signatures are organized into clusters as a function of the distances between each signature, and each signature is associated with a soft migration cost specific to that signature's cluster. A soft cost for migrating an application that requires multiple datasets may be determined by adding the migration costs associated with each of the multiple datasets.

When the data dictionary is completed, a switchover point is reached and thenceforth, incoming queries are served using the first type of processing entity.

A snapshot coordinator initiates a two-phase commit to perform a snapshot epoch transition. The coordinator sends prepare messages to the nodes. In response, a node sends a response to the coordinator, stops issuing writes to the file system, sets a timer, and waits for a commit message. Upon receiving a response from all nodes, the coordinator sends a commit message. Upon receiving the commit or the timer expiring, the nodes increment an epoch counter and begin issuing writes to the file system tagged with the new epoch and indicating that a copy-on-write operation be performed. The transition is successful if all nodes respond to the request message; otherwise, the two-phase commit is retried.
