    摘要: A technique for operating a client node in a clustered file system includes allocating a number of blocks during a first time window and tracking the number of blocks allocated during the first time window. The technique further includes transmitting a block allocation request to a server node of the clustered file system for a number of requested blocks in response to a number of free blocks in a client-side block map reaching a first threshold value. In this case, the number of the requested blocks is based on the number of blocks allocated by the client node during the first time window.

    摘要: An apparatus, system, and method are disclosed for differential data backup using snapshot on-write data. A snapshot module maintains an on-write data structure that captures a point-in-time or temporal instance of a data set by tracking modifications to data blocks of a data set. A backup module copies the data set to a backup data storage device as a full data set backup. In addition, the backup module copies each modified data block indicated by the on-write data structure and a differential time stamp to the backup data storage device as a differential data set backup. The full data set backup and one or more differential data set backups form a plurality of temporal instances of the data set. In one embodiment, a restore module recovers a selected instance of the data set responsive to receiving a restore command by copying the full data set backup to a target data storage device. In addition, the restore module may copy the differential data set backup to the target data storage device if the differential time stamp corresponds to a target time value.

    摘要: A processor selects file system metadata. A processor identifies each unit of data in a file system. The processor determines if the unit of data contains file system metadata. The processor writes a unit of data of metadata to a diagnostic file system, provided it was determined that the unit of data contains file system metadata. The processor then determines if the unit of data contains user data. If the unit of data contains user data, the processor writes a sparse object to the diagnostic file.

    摘要: An operating system creates a current sparse object in a diagnostic file system. Then the operating system processes a change to data contained in a block. The operating system determines if the change is to a metadata block. The operating system encodes the change in a journal log, in response to a determination that the change is to a metadata block. In addition, the operating system writes the block to the current sparse object, in response to a determination that the change is to a metadata block.
