    摘要: In accordance with one or more embodiments, an inode implemented file system may be utilized to support both offline and inline deduplication. When the first content is stored in the storage medium, one inode is used to associate a filename with the data blocks where the first content is stored. When a second content that is a duplicate of the first content is to be stored, then a parent inode is created to point to the data blocks in which a copy of the first content is stored. Further, two inodes are created, one representing the first content and the other representing the second content. Both inodes point to the same parent inode that points to the data blocks where the first content is stored.

    摘要: Logging and storage transactions in a database are directed to a single storage server. A modification of a database record is written only once to a log record on the storage server. Subsequently, the storage server interprets the database log records, and modifies the database storage accordingly. The number of bytes written to storage is potentially reduced by fifty percent as compared to writing the log record and then writing the modified database record to the storage server.

    摘要: Disclosed is a technique for maintaining consistency of data. One or more blocks of data identified by a first structure are copied to form a consistent set of data. While not acknowledging completion of write requests to any blocks of data, a second structure is created, wherein the second structure indicates which blocks of data are modified while the consistent set of data is being formed. Also disclosed is a technique for asynchronous copy. Indicators are updated in a first structure for one or more blocks of data, wherein each indicator in the first structure indicates whether a corresponding block of data was modified since the block of data was last sent to remote storage. While copying the blocks of data identified by the indicators in the first structure as having been modified since the blocks of data were last sent to remote storage, indicators in a second structure are updated for the one or more blocks of data, wherein each indicator in the second structure indicates whether a corresponding block of data was modified while a consistent set of data is being formed.
