Each node in the set performs data deduplication on a different work set. In performing data deduplication, each node may store metadata describing where shared chunks of data are maintained in a distributed file system. The shared chunks of data are two or more sequences of bytes which appear in two or more of said plurality of files.

Abstract: Backup metadata deletion based on backup data deletion is described. A system receives a request to delete a backup data set associated with a host, a path, and a backup time. The system identifies a backup metadata object associated with the host and the path. The system determines whether the requested backup time is the earliest backup time associated with any backup data set associated with the host. The system determines whether the identified backup metadata object is a backup metadata deletion object associated with the backup time if the backup time is the earliest backup time. The system deletes the identified backup metadata object if the identified backup metadata object is a backup metadata deletion object associated with the backup time.

Abstract: Systems and methods for throttling logging processes in presence of system resource contention. Logging processes that contend with non-logging processes for resources can sometimes be throttled to more equitably share system resources. A method embodiment commences by establishing a set of throttling rules that are to be observed by the logging processes running on the system. While logging processes and non-logging processes are running, a monitor records system resource usage and other system conditions. When a process manager determines that the resources consumed by the combination of the logging processes and the non-logging processes exceed a threshold, then any currently-applicable throttling rules fire so as to prescribe throttling levels.

Abstract: Directory attributes are provided so that the time for creating an incremental backup of a file system by a scan of the file system tree is proportional generally to the number of files that change between backups instead of the number of files in the file system. A tree modification attribute indicates whether or not any file in a directory tree has changed since the last backup. If no file has changed in the directory tree, then the entire tree is skipped during the scan for changed files. In addition, a list is compiled of the files in the directory that represent branches having at least one changed file, so that the list is scanned instead of the directory entries. When a file is changed for the first time since the last backup, the file is queued so that the directory attributes are updated in a background process.

Abstract: In a backup method, a source storage device sends data to a backup storage device. The source storage device contains a processor and a cache. The processor receives a write data request which includes target data. And then, the processor reads a first period ID recorded in a period ID table, wherein the first period ID is corresponding to a first period. Next, the processor modifies the write data request by attaching the first period ID to the target data and writes the modified write data request into the cache. After a backup task corresponding to the first period is triggered, the processor identifies a second period ID. The second period ID corresponds to a previous period up to which data received by the source storage device have been duplicated to the backup storage device. And then, the processor obtains data received after the period corresponding to the second period ID and up to the first period and sends the obtained data to the backup storage device.

Abstract: Systems and methods of using delta partitions for backup and restore are disclosed. An example method may include after a full backup, separating change information from static information.

Abstract: A method and system for allocating shared storage using one or more classification schemes is provided. One allocation method receives a storage request for provisioning storage from a class storage group configurable to share storage with more than one filesystems. Part of fulfilling this request includes associating a class and at least one corresponding storage allocation constraint with the storage request. The one or more storage allocation constraints can be used subsequently to determine if there is a sufficient amount of shared storage in the class storage group to fulfill the request. Accordingly, aspects of the present invention use at least one storage allocation constraint in determining if the storage allocation constraint for the class associated with the storage request allows allocation of shared storage to fulfill the request. When the storage allocation constraint allows, one implementation performs a provisioning of storage from the shared storage in class storage group.

Abstract: The efficiency of data de-duplication may be improved by storing related file data in a single container, or in multiple linked containers, of a history. Additionally, the efficiency of data de-duplication may be improved when shorter hash tables are used to reference historical data in a history. Shorter hash tables may be achieved by storing fewer than all the hash values obtained for a given amount of historical data. Further, the efficiency of data de-duplication may be improved by comparing related incoming file data with historical data from a container without hashing/chunking the remaining file data upon matching an earlier chunk of the incoming file data to the container.

Abstract: A system reserves and manages a hidden service partition through components of the hardware platform of a computing device. The hidden partition is not accessible by way of a host operating system on the computing device. A hardware platform controller provisions a portion of nonvolatile storage through configuration settings of the hardware platform controller. When the host system requests settings related to storage in the system, the request is routed through the interfaces of the hardware platform, and the hardware platform controller reports in accordance with the configuration settings, hiding the service partition. The hidden partition is dynamically modifiable through secure remote access to the hardware platform controller, not through the host system such as operating system or BIOS.
