摘要： A block based backup system may perform several partial backups to incrementally transfer backup information to a backup system. Each partial backup may build on the previous backup and the partial backups may be marked as unable to be used for restoration. In some cases, the partial backups may be portions of a file system snapshot, while in other cases, the partial backups may include any changes that occurred since a last partial backup. The size of the partial backups may be dynamically changed depending on network connections, workloads, and other factors.
摘要翻译：基于块的备份系统可以执行几个部分备份以将备份信息递增地传输到备份系统。每个部分备份可以建立在以前的备份上，部分备份可能被标记为无法用于恢复。在某些情况下，部分备份可能是文件系统快照的一部分，而在其他情况下，部分备份可能包括自上次部分备份以来发生的任何更改。部分备份的大小可能会根据网络连接，工作负载和其他因素而动态更改。

摘要： A block based backup system may store backed up data from multiple clients by maintaining backup databases for each client, where each backup database may include blocks of data. The backup system may perform a de-duplication process by examining the databases to identify common blocks and moving the common blocks to a common database. The common blocks may be removed from the client backup databases and a pointer substituted for the data, thus compacting the client backup databases. The de-duplication operation may be performed at an opportunistic time, such as after the clients have completed any data transfer to the backup system.
摘要翻译：基于块的备份系统可以通过维护每个客户端的备份数据库来存储来自多个客户端的备份数据，其中每个备份数据库可以包括数据块。备份系统可以通过检查数据库来识别公共块并将公共块移动到公共数据库来执行重复数据删除过程。可以从客户端备份数据库中删除公共块，并将指针替换为数据，从而压缩客户端备份数据库。重复数据删除操作可以在机会时间执行，例如在客户端完成对备份系统的任何数据传送之后。

US20120102088A1 PRIORITIZED CLIENT-SERVER BACKUP SCHEDULING 审中-公开

摘要： A prioritized backup time within a predetermined backup window can be calculated. The calculated backup time can be a time to initiate a backup operation to backup information from a client to a server. The calculation of the backup time can use a priority of the client and/or a degree of compliance of the client with a backup policy. An initiation of the backup operation by the client can be scheduled to occur at the calculated backup time, and the backup operation can be initiated. Other prioritized scheduling techniques can also be used, such as prioritized backup queue ordering, prioritized preemption of partially complete backup operations, and/or server override of the client's calculated backup time to begin a backup operation on demand.
摘要翻译：可以计算预定备份窗口内的优先备份时间。计算的备份时间可以是启动备份操作以将信息从客户端备份到服务器的时间。备份时间的计算可以使用客户端的优先级和/或客户端与备份策略的一致程度。客户端的备份操作的启动可以在计算的备份时间进行调度，并且可以启动备份操作。还可以使用其他优先排序的调度技术，例如优先排序的备份队列排序，部分完成备份操作的优先级抢占，和/或客户端计算的备份时间的服务器覆盖，以便按需开始备份操作。
