Abstract: During conversion and transfer of data from a physical machine to a virtual hard disk, a transmuter generates a catalog of contents of the physical machine. Catalog entries are compared to a set of alterations templates which alter matching data. The altered data is then stored in the virtual hard disk. Alterations templates may include filters that exclude unwanted or duplicated catalog entries, mapping filters that transfer source catalog entries to target locations on the virtual hard disk, and add-on filters that add additional data or location references to catalog entries. The disclosed process allows modifications to be made in a systematic way during data transfer.

Abstract: System and method for the opportunistic allocation of copies of data across data storage resources in file systems. Embodiments may opportunistically and transparently trade storage space in a file system for performance. In embodiments, when data is stored to the file system, copies of the data may be opportunistically stored to two or more data storage resources. The data may then be opportunistically accessed from a less active resource if the resource storing a primary copy of the data is busy. The opportunistically stored copies of data remain online in the file system. In hierarchical file systems or tiered storage hierarchies, embodiments may allow higher-level storage tiers to “borrow” performance from lower-level tiers by opportunistically allocating copies of data from a higher-level tier within a lower-level tier. Copies of data stored on a data storage resource may be deleted if storage space is needed on that data storage resource.

Abstract: Technology is disclosed for using computing devices (“the devices”) of a user as an edge cache of a distributed backup system to stream video files. In the distributed backup system, the user can store different data files of the user at different devices of the user and/or at a server. For example, the user may store video files at one of the devices of the user (“a first device”) in addition to storing at the server. When the user requests to stream a particular video file to a particular device, the technology streams the video file to the particular device either from the server or from the first device. If the first device is in proximity to the particular device, the video file is streamed from the first device instead of from the server, thereby minimizing the latency involved in streaming the video file from the server.

Abstract: The distributed computing backup and recovery (DCBR) system and method provide backup and recovery for distributed computing models (e.g., NoSQL). The DCBR system extends the protections from server node-level failure and introduces persistence in time so that the evolving data set may be stored and recovered to a past point in time. The DCBR system, instead of performing backup and recovery for an entire dataset, may be configured to apply to a subset of data. Instead of keeping or recovering snapshots of the entire dataset which requires the entire cluster, the DCBR system identifies the particular nodes and/or archive files where the dataset resides so that backup or recovery may be done with a much smaller number of nodes.

The creation of the new cluster network environment may be based at least in part on cluster configuration data.

Abstract: A method for asynchronously replicating data onto a tape medium is implemented at one or more server computers associated with a distributed storage system and connected to a tape storage system. Upon receiving a first request from a client for storing an object within the tape storage system, a server computer stores the object within a staging sub-system of the distributed storage system and provides a first response to the requesting client. If a predefined condition is met, the server computer transfers objects from the staging sub-system to the tape storage system. For each transferred object, the server computer adds a reference to the object to a tape management sub-system, identifies a corresponding parent object associated with the object and its metadata within a parent object management sub-system of the distributed storage system, and updates the parent object's metadata to include the object's location within the tape storage system.

Abstract: This disclosure enables a user to incrementally increase or decrease the size of the cluster and, in particular, to incrementally increase or decrease the number of map regions implemented in a metadata manager associated with the cluster while maintaining availability of the cluster. In a representative embodiment, a configurable target map size is identified, either manually (e.g., by the user) or programmatically. If the target map size is found to be within an acceptable value (given the available node configuration), a procedure to create a new map is triggered. The new map preferably is generated as follows. Initially, one or more new temporary region(s) are created either to split or join the existing regions (depending on whether the map is being increased or decreased). For each temporary region, the process also generates MDPL backup regions. Metadata from an original region (or regions) is then migrated to the temporary region(s).

Abstract: Technology is disclosed for selectively backing up audio files and video files of a user in a distributed backup system. In the distributed backup system, the user can define various policies for storing different data files of the user at different devices of the user and/or at a server. For example, the user may define a policy for storing video files on a device having a bigger display and audio files on a device which the user uses more often than the other devices. When a backup is initiated on a particular device, the technology identifies target devices based on the defined policies, and transmits the audio and video files from the particular device to the corresponding target devices. The audio and video files are transmitted via the server or directly if the target devices are in proximity to the particular device.
