摘要： A system and method of operating a filesystem for managing filesystem objects is disclosed. The filesystem objects are characterized by metadata parameters included in a global directory object arranged in a plurality of global directory object (GDO) pages. Responsive to receiving a request for creating a new filesystem object, a parent key is obtained. The parent key is indicative of an identifier of a direct parent directory requested for hosting the new filesystem object. A target page that corresponds to the parent key is located within the plurality of GDO pages. The target page further includes a direct parent directory metadata record associated with the direct parent key and includes metadata parameters related to the direct parent directory. An object key is created as corresponding to the same target page, thereby enabling accommodation of an object metadata record, related to the new filesystem object, on the target page.

摘要： A virtual allocation unit is allocated in a virtual address space corresponding to a filesystem, in response to an allocation requirement, related to a logical object in the filesystem. The size of the virtual allocation unit is determined in accordance with the current physical size of the logical object. The size of the virtual allocation unit is substantially larger than a size required with respect to the allocation requirement. Physical block address ranges are allocated in a physical storage space, in response to subsequent write requests, related to the logical object. Each physical block address range is associated with a respective portion of the virtual allocation unit.
摘要翻译：响应于与文件系统中的逻辑对象相关的分配要求，在与文件系统相对应的虚拟地址空间中分配虚拟分配单元。根据逻辑对象的当前物理大小来确定虚拟分配单元的大小。虚拟分配单元的大小明显大于相对于分配要求所需的大小。物理块地址范围被分配在物理存储空间中，以响应与逻辑对象相关的后续写入请求。每个物理块地址范围与虚拟分配单元的相应部分相关联。

摘要： A method is provided for making a backup copy of the content of a memory, e.g., a database, such that the memory is divided into a plurality of segments and a backup copy of individual ones of the segments is made during a respective one of a plurality of independent backup sessions. Each segment may be a predetermined percentage of the memory, and the independent sessions may be separated from one another by a predetermined duration of time, e.g., a day. A full backup of the memory is thus completed during a last one of the backup sessions. An incremental backup copy may be made for each of the blocks of segments whose contents has changed since a previous backup session.
摘要翻译：提供了一种用于制作存储器（例如数据库）的内容的备份副本的方法，使得存储器被划分成多个段，并且在各个段中的各个段中进行备份，多个独立备份会话。每个段可以是存储器的预定百分比，并且独立会话可以彼此隔开预定的持续时间，例如一天。因此，在最后一个备份会话期间完成内存的完全备份。对于自上一个备份会话以来内容已经改变的段的每个块，可以进行增量备份。

摘要： A facility is provided for storing in a backup memory only those blocks of a file, or disk partition, which differ from corresponding blocks forming an earlier version of the file. Specifically, a file is divided into a number of blocks and a "signature" is generated for each such block. A block is then stored in the backup memory only if its associated signature differs from a signature generated for an earlier version of the block. In addition, if two blocks of the current version of the file have identical signatures and are to be stored in the backup memory, then only one of the two blocks is stored in the memory and a simple message indicating that the other block is equal to the one block is stored in the memory for the other block. Further, the application of such signatures is advantageously applied to the opposite case of restoring a file using copies of previous versions of the file that are stored in the backup memory.
摘要翻译：提供了用于仅在备份存储器中存储与形成文件的较早版本的相应块不同的文件或磁盘分区的块的设施。具体地，将文件划分为多个块，并为每个这样的块生成“签名”。然后，只有当其相关联的签名与为块的早期版本生成的签名不同时，才将该块存储在备份存储器中。另外，如果文件的当前版本的两个块具有相同的签名并且要存储在备份存储器中，则只有两个块中只有一个被存储在存储器中，并且一个简单的消息指示另一个块等于一个块被存储在另一个块的存储器中。此外，这种签名的应用有利地应用于使用存储在备份存储器中的文件的先前版本的副本来恢复文件的相反的情况。
