Abstract: This document describes techniques for effecting a virtual disk. In an exemplary configuration, a virtual disk file can be associated with a log that acts as both a log and a check point record. When a log entry is generated, information that identifies the tail can be stored therein. This information can be used in the event that virtual disk file is improperly closed, i.e., a crash or power failure occurs, to discover a sequence of log entries to replay. In addition to the foregoing, other techniques are described in the claims, detailed description, and figures.
Abstract translation: 本文档描述了影响虚拟磁盘的技术。 在示例性配置中，虚拟磁盘文件可以与充当日志和检查点记录的日志相关联。 当生成日志条目时，可以存储标识尾部的信息。 在虚拟磁盘文件不正确关闭的情况下，即发生崩溃或电源故障的情况下，可以使用此信息来发现要重播的日志条目序列。 除了上述之外，在权利要求书，详细描述和附图中描述了其它技术。
