摘要： A system, method and computer readable medium for providing a snapshot of a subset of a file system. A first snapshot of a first set of source files in a file system is generated. The first snapshot includes an inode corresponding to each source file in the first set of files. Stored in each inode is a first identifier associated with the first set of files and a second identifier associated with the time of the first snapshot. Next, a second snapshot of a second set of source files is taken. The second snapshot includes an inode corresponding to each source file in the second set of files. Stored in each inode are a first identifier and a second identifier. Subsequent snapshots are taken every first period and every second period for the first set of files and the second set of files, respectively.

摘要： A technique for restoring file systems by applying full and incremental backups together while streaming them from multiple devices provides a faster system restore from a full backup where incremental backups must also be applied. A first storage device streams the full backup while at least one second storage device streams at least one incremental backup. As files are detected in the incremental backup, they are written instead of the corresponding file in the full backup. Incremental backups can be pre-merged to reduce their number to one less than a number of storage devices available to stream the backups, so that the full backup can be streamed along with the pre-merged incremental backup(s) to restore the file system.
摘要翻译：通过将多个设备进行全套备份和增量备份一起应用来恢复文件系统的一种技术可以从必须应用增量备份的完整备份提供更快的系统还原。第一存储设备流传输完整备份，而至少一个第二存储设备流至少一个增量备份。当增量备份中检测到文件时，它们将被写入而不是完整备份中的相应文件。增量备份可以预合并，将其数量减少到少于可用于流式传输备份的多个存储设备，以便完整备份与预合并的增量备份一起进行流式传输以还原文件系统。

摘要： During file backup to an off-line storage facility, attributes are included which facilitate the placement of the file into a proper pool during a subsequent restoration operation. This avoids multiple data transfers that may have otherwise been occasioned as a result of improper pool selection during the restore due to the loss or to the unavailability of necessary file attributes when the file was restored.

摘要： File system restoration is made more flexible through the use of indicators of individual file restoration status throughout the restoration process. Such indicators are particularly useful in the restoration of large file systems where, for example, the number of files may range upwards of several hundred million. Since file system restoration for large systems takes such a relatively long time, the present invention provides various degrees of individual file access even as the restoration process is being carried out. During file system restoration times, file access may be full or limited to a file's attributes. Most advantageously, the present invention is capable of providing full, dynamically driven (on-demand) file access even during file system restoration operations.
摘要翻译：通过在整个恢复过程中使用单个文件恢复状态的指示器，使文件系统恢复更加灵活。这样的指示器在恢复大型文件系统中特别有用，例如文件数量可能在几亿以上。由于大型系统的文件系统恢复需要相当长的时间，所以即使正在执行恢复处理，本发明也提供了各种文件访问的程度。在文件系统恢复时间内，文件访问可能已满或限于文件的属性。最有利的是，即使在文件系统恢复操作期间，本发明也能够提供完全的动态驱动（按需）文件访问。

摘要： A system, method and computer readable medium for providing a writable file system snapshot with ditto address feature is disclosed. In an embodiment of the present invention, the method includes accessing a first file system snapshot in a set of file system snapshots. A snapshot includes data contents comprising at least one shadow inode or at least one shadow inode and at least one data block corresponding to the shadow inode. The data contents of the first snapshot are copied and written to the next oldest file system snapshot. Subsequently, the data contents of the first snapshot are modified in accordance with modifications to at least one source file corresponding to the first snapshot. Then, a next most recent file system snapshot is accessed. The data contents of the next most recent snapshot are copied and written to the first file system snapshot.

摘要： A selective restore technique for restoring file systems within computer systems provides on-demand access during the restore process, while preventing users from slowing the restore process by generating random accesses to files that have not yet been restored, early in the restore process. The restored files are grouped into multiple groups of files, which correspond to multiple phases of the restore process. On-demand requests may be locked out for some or all users during the first one or more phases of the restore, while they are permitted for the subsequent phases, ensuring that critical files needed by all users will be available before the backup process is interrupted by on-demand accesses. The groups are generally organized by elapsed time since last access or modification, and may be organized at restore time or during periodic back-up operations so that the files may be similarly organized in the backup media.
摘要翻译：用于恢复计算机系统中的文件系统的选择性还原技术在恢复过程中提供按需访问，同时防止用户通过在还原过程的早期生成对尚未还原的文件的随机访问来减缓恢复过程。恢复的文件被分组成多组文件，这些文件对应于恢复过程的多个阶段。在恢复的第一个或多个阶段期间，一些或所有用户可能会锁定按需请求，而允许后续阶段允许所有用户在备份过程中断之前所需的关键文件可用按需访问。这些组通常按照自上次访问或修改之后的经过时间组织，并且可以在恢复时间或周期性备份操作期间被组织，使得文件可以类似地组织在备份介质中。

摘要： Space is allocated on data storage devices in proportion to weights associated with the storage devices. The weights can be dynamically adjusted at any time in order to accommodate changes in the system and to better utilize the storage devices. The technique used to perform the allocating is independent of the weights used by the allocating. Further, the allocation technique can accommodate general purpose data streams having varying lengths and/or varying access patterns, as well as special purpose data streams, such as video streams.

摘要： A method is provided for managing the storage of a file that has been selected for migration from a first storage level within a file system to a second storage level. The method comprises copying each of one or more data blocks of the selected file that are stored in the first storage level at a physical disk address maintained in a corresponding reference of an inode for the selected file from the first storage level to the second storage level; maintaining a logical ditto address in each reference of an inode for each snapshot file in the file system that refers to one of the one or more data blocks of the selected file that were copied to the second storage level; and updating the file system to include a managed region for controlling access to the one or more data blocks through the inode for the selected file.
