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.
