摘要： A method is disclosed for maintaining consistent states of a file system. The file system progresses from one self-consistent state to another self-consistent state. The set of self-consistent blocks on disk that is rooted by a root inode is referred to as a consistency point. The root inode is stored in a file system information structure. To implement consistency points, new data is written to unallocated blocks on disk. A new consistency point occurs when the file system information structure is updated by writing a new root inode into it. Thus, as long as the root inode is not updated, the state of the file system represented on disk does not change. The method also creates snapshots that are user-accessible read-only copies of the file system. A snapshot uses no disk space when it is initially created. It is designed so that many different snapshots can be created for the same file system. Unlike prior art file systems that create a done by duplicating an entire inode file and all indirect blocks, the method of the present invention duplicates only the inode that describes the inode file. A multi-bit free-block map file is used to prevent data referenced by snapshots from being overwritten on disk.
摘要翻译：公开了一种用于维持文件系统的一致状态的方法。文件系统从一个自我一致的状态进展到另一个自我一致的状态。由根inode生成的磁盘上的一组自相关块被称为一致性点。根inode存储在文件系统信息结构中。要实现一致性点，新数据将写入磁盘上的未分配块。当通过在其中写入新的根节点来更新文件系统信息结构时，会发生新的一致性点。因此，只要root inode不被更新，在磁盘上表示的文件系统的状态就不会改变。该方法还创建快照，这些快照是文件系统的用户可访问的只读副本。快照在最初创建时不使用磁盘空间。它的设计使得可以为同一个文件系统创建许多不同的快照。与通过复制整个inode文件和所有间接块创建完成的现有技术文件系统不同，本发明的方法仅复制描述了inode文件的inode。多位自由块映射文件用于防止快照引用的数据被覆盖在磁盘上。

摘要： An information management system provides a data deduplication system that uses a primary table, a deduplication chunk table, and a chunk integrity table to ensure that a referenced deduplicated data block is only verified once during the data verification of a backup or other replication operation. The data deduplication system may reduce the computational and storage overhead associated with traditional data verification processes. The primary table, the deduplication chunk table, and the chunk integrity table, all of which are stored in a deduplication database, can also ensure synchronization between the deduplication database and secondary storage devices.

摘要： There are provided methods and systems for transferring requested data over a node chain from a source node to a destination node through at least two intermediate nodes. A method includes identifying, at a file system level, at each of the at least two intermediate nodes, prior data previously sent to or received from a subsequent node in the node chain that matches at least a portion of the requested data. The method also includes transmitting, to the subsequent node, at least one pointer to the prior data and a reconstruction recipe for reconstructing the requested data at the subsequent node based on at least the at least one pointer, when the prior data matches at least the portion of the requested data.

摘要： System and method for hybrid distribution mode in massively parallel processing (MPP) database preventing storage imbalance issues caused by data skew. Key values of the database are identified as outliers if records of those keys cause database skew. In hybrid mode, records having the outlier key values are distributed using a random distribution scheme. Other records are distributed using a hash distribution scheme. A threshold skew amount is configurable for the system. Record lookups, insertions, deletions, and updates are processed according to a query plan optimized for the distribution mode of the records referenced in a database query.
