摘要： 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.
摘要翻译：提供目录属性，以便通过文件系统树的扫描来创建文件系统的增量备份的时间通常与备份之间而不是文件系统中的文件数量的文件数量成比例。树修改属性指示自上次备份以来目录树中的任何文件是否已更改。如果目录树中没有文件已更改，则在扫描更改的文件期间将跳过整个树。另外，编译目录中表示具有至少一个已更改文件的分支的文件的列表，以便扫描列表而不是目录条目。当文件自上次备份以来首次更改文件时，文件将排队，以便在后台进程中更新目录属性。

摘要： A waste treatment plant (1) comprises an incinerator unit (30) and an autoclave unit (9) and operates such that steam for the autoclave is generated from heat in the incinerator and contaminated water from the autoclave is used to control the temperature in the incinerator, the contamination being destroyed in the process. Exhaust gas from the incinerator is used to reduce the water content of waste treated in the autoclave. Steam generated by the incinerator is available for plant washing operations, to wash bins that supplied waste to the plant before the bins are returned.
摘要翻译：废物处理设备（1）包括焚化炉单元（30）和高压灭菌器单元（9），并且操作使得在焚烧炉中由热量产生高压釜的蒸汽，并且使用来自高压釜的污染水来控制温度焚化炉，污染物在此过程中被破坏。来自焚烧炉的废气用于降低在高压釜中处理的废物的含水量。焚烧炉产生的蒸汽可用于植物洗涤操作，以便在垃圾箱返回之前清洗提供废物的垃圾箱。

摘要： An improved technique generates formatted file system metadata in increments only when metadata for those increments are specifically requested. A location on a storage volume designated for storing file system metadata is read and tested to determine whether it stores a predetermined pattern indicating an unformatted state. If the pattern is found, metadata for the designated location are generated and returned. Otherwise, metadata are returned as initially read from the storage volume.

摘要： In a file server, a file system is built upon a volume of data storage. The file system includes multiple cylinder groups. Each cylinder group includes file system blocks. The file system blocks include allocated blocks and free blocks. The volume includes slices of storage, and each slice stores at least one of the cylinder groups. A hierarchical slice map has a top level that includes a count of free blocks in the file system, an upper level that includes a count of free blocks in groups of the slices, an intermediate level that includes a count of the free blocks in sub-groups of the slices, and a bottom level that includes a count of the free blocks in each slice of storage. To find a free block for allocation to a file, the slice map hierarchy is searched in a top-down fashion.

摘要： For enabling a fast reverse lookup of parent directories storing records of hard links to a specified regular file, a file system manager maintains a hard link database (HLDB) storing information for addressing hard links to the regular files having multiple hard links. The HLDB contains a corresponding HLDB file for each regular file having multiple hard links. In a preferred implementation, the inode of each regular file stores the addressing information for one hard link to the regular file, a corresponding HLDB file stores the addressing information for other hard links to the regular file, each HLDB file is a directory accessed by invoking file system manager directory access routines, and the HLDB has a directory tree providing a multi-level hash index for searching the HLDB given the inode number of a regular file.

摘要： To recover from partial writes of metadata transactions to a file system log, a redundancy check is added to each log record. Upon re-boot of the file server, the file system is recovered by finding the last valid record in the log, and then replaying records from the log into the on-disk file system. The replay is terminated prior to the last valid record upon reaching any record with a bad redundancy check. A “fsck” is performed on the file system prior to granting client access to the file system only if the log recovery was terminated prior to the last valid record upon reaching a record with a bad redundancy check and the position of the records in the log indicates that this record with a bad redundancy check could not have been written to the log concurrently with the last valid record.
摘要翻译：要从元数据事务的部分写入恢复到文件系统日志，将向每个日志记录添加冗余检查。重新启动文件服务器后，通过查找日志中的最后一个有效记录来恢复文件系统，然后将日志中的记录重播到磁盘文件系统。在到达任何具有不良冗余检查的记录之后，重播将在最后一次有效记录之前终止。只有在达到具有不良冗余检查的记录和记录在日志中的位置的最后有效记录之前，如果日志恢复被终止，则在授予客户端对文件系统的访问之前，对文件系统执行“fsck” 表示该冗余校验错误的记录不能与最后一个有效记录并发写入日志。
