摘要： A method and system thereof for dynamically configuring a device, adapted to be communicatively coupled in a wireless personal area network, with an attribute corresponding to a characteristic of the device. In one embodiment, the method involves receiving an attribute setting corresponding to characteristics of the device and implementing a corresponding configuration state. In this embodiment, the configuration state activates a corresponding device configuration. In one embodiment, the attribute setting constitutes a discretely variable value conforming to the degree of mobility of the device. In one embodiment, an attribute setting constitutes a discretely variable value conforming to the location of the device. In one embodiment, two attribute settings constitute discretely variable values conforming, one to the degree of mobility of the device, and the other to its location. In one embodiment, the device and network incorporate communicative capability compliant with the Bluetooth specification.

摘要： An improved mechanism for processing client requests is disclosed. The first time a client request for a particular resource is received by a server, it is processed by stepping through a configuration file, and selectively executing directives specified in the configuration file. As the request is processed, a list of executed directives is compiled. This list of directives is stored for future reference. The next time a request for that same resource is received, the configuration file is not consulted. Instead, the stored list of directives is accessed and used to process the request. More specifically, all of the directives on the list are executed to process the request. Processing the subsequent request in this way eliminates much of the overhead associated with request processing. There is no need to open or to step through the configuration file, and there is no need to step through the directives themselves. By removing this overhead for all requests for a resource after the first, request processing efficiency is significantly improved.
摘要翻译：公开了一种用于处理客户端请求的改进机制。客户端首次接收到特定资源的请求时，会通过配置文件进行处理，并选择性地执行配置文件中指定的指令。当请求被处理时，编译执行的指令的列表。该指令列表存储以供将来参考。下次接收到同一资源的请求时，不会查询配置文件。相反，存储的指令列表被访问并用于处理请求。更具体地说，执行列表中的所有指令来处理请求。以这种方式处理后续请求消除了与请求处理相关联的大量开销。没有必要打开或者逐步通过配置文件，并且不需要自己逐步完成指令。通过在第一次之后消除对资源的所有请求的开销，请求处理效率显着提高。

摘要： A backup administrator can backup files from a production server on any of a plurality of different bases. In particular, some files can be replicated on a changed-byte basis. In other cases, files can be backed up by replicating updated copies of the entire file, or even byte blocks of the file. Determinations as to how a replication agent will back up a certain file or set of files can be made by a backup administrator, automatically through a predefined logic, or dynamically based on defined criteria. Corresponding agents at the production server can then flag these files as indicated. Thus, at a later point, when the DPM server requests the updates of each file, the production server can either send over copies of the changed file bytes, entire copies of the changed file itself, or even changed blocks of a file, as appropriate.
摘要翻译：备份管理员可以在多个不同的基础上的任何一个上从生产服务器备份文件。特别地，一些文件可以在更改字节的基础上进行复制。在其他情况下，可以通过复制整个文件的更新副本，甚至文件的字节块来备份文件。关于复制代理如何备份某个文件或一组文件的确定可以由备份管理员自动通过预定义的逻辑，或动态地基于定义的标准来进行。生产服务器上的相应代理可以按照指示标记这些文件。因此，在稍后的时刻，当DPM服务器请求每个文件的更新时，生产服务器可以根据需要发送改变的文件字节的副本，改变的文件本身的整个副本，甚至文件的更改的块。

摘要： Data can be protected at a production server in a virtually continuous fashion, without necessarily imposing severe constraints on the source application(s). For example, a production server can create an application-consistent backup of one or more volumes, the backups corresponding to a first instance in time. A volume filter driver can monitor data changes in each volume using an in-memory bitmap, while a log file and/or update sequence number journal can keep track of which files have been added to or updated. The volume updates are also consistent for an instance (later) in time. At the next replication cycle, such as every few minutes (however configured), the volume filter driver passes each in-memory bitmap to the physical disk on the production server. The production server then sends the updates to the backup server, which thus stores application-consistent backups for the volume for multiple instances of time.
摘要翻译：可以在生产服务器上以几乎连续的方式保护数据，而不必对源应用程序施加严格的约束。例如，生产服务器可以创建一个或多个卷的应用程序一致性备份，备份与时间对应的第一个实例。卷过滤器驱动程序可以使用内存中位图来监视每个卷中的数据更改，而日志文件和/或更新序列号日志可以跟踪哪些文件已添加到或已更新。对于一个实例（稍后）的时间，卷更新也是一致的。在下一个复制周期（例如每隔几分钟配置一次），卷过滤器驱动程序将每个内存中的位图传递到生产服务器上的物理磁盘。然后，生产服务器将更新发送到备份服务器，从而存储多个时间实例的卷的应用程序一致性备份。

摘要： A method for verifying data copies generated by a data protection system is provided. In accordance with the method, intents for selecting a data copy to be verified are determined. The intents may specify a time period after which data is to be verified and an interval for which the verification is to be repeated. Additionally, utilizing the intents, a data copy matching those intents is identified and verified. A data copy may be verified by comparing a checksum of the data copy with a known checksum value. If the data copy fails to be verified, a copy of the data copy is generated.

摘要： A backup system in accordance with an implementation of the present invention includes one or more light-weight (i.e., stateless) storage nodes that are positioned close enough to one or more assigned production servers to enable as rapid and efficient a data recovery as possible. The one or more light-weight storage nodes are driven by, and implement backup policies in accordance with, control settings determined by and received from a centralized backup server. Changes to the control settings are simply produced at the centralized backup server and propagated to each storage node in the system. In addition to efficient backup times, general backup administration can be greatly simplified at least in part since a large number of production serves can be serviced through a small or large number of light-weight storage nodes, which in turn can be managed by a single centralized backup server.
摘要翻译：根据本发明的实现的备份系统包括一个或多个轻量级（即，无状态）存储节点，其被定位成足够靠近一个或多个分配的生产服务器，以使得尽可能快速和有效地进行数据恢复。一个或多个轻量级存储节点由根据由集中式备份服务器确定和接收的控制设置来驱动并实施备份策略。对控制设置的更改仅在集中式备份服务器上生成，并传播到系统中的每个存储节点。除了有效的备份时间之外，至少部分地可以大大简化总体备份管理，因为可以通过少量或大量的轻量级存储节点来服务大量的生产服务，这又可以由单个管理集中备份服务器。
