An artificial stone is disclosed for use in creating a covering for a supporting surface. The artificial stone includes a body for placement on the supporting surface, which is shaped for mating engagement with like stones with intermediate perimeter joints to produce a continuous surface covering. The stone has a facing surface on the body, which facing surface has a contour defining a surface area and is subdivided by at least one simulated joint into a major surface portion and at least one minor surface portion. The major surface portion is free of simulated joints and extends over at least about 60% of the total surface of the facing surface. The stone further includes at least one perimeter recess in the body for generating a gap between the stone and another like stone in mating engagement therewith, which gap is wider than adjacent the adjoining perimeter joint. Stones of this construction can easily be arranged in a regular, repeated pattern to generate a continuous covering for the supporting surface with the surface of the resulting covering having an irregular, natural appearance. The irregular top contours of the stones, the uneven division of the facing surface and the perimeter recesses and the resulting gaps between mating stones simulate the appearance of a natural stone surface covering for walkways, roadways, pavements or walls.

Rapid restoration of file system usage in very large file systems

File system restoration is made more flexible through the use of indicators of individual file restoration status throughout the restoration process. Such indicators are particularly useful in the restoration of large file systems where, for example, the number of files may range upwards of several hundred million. Since file system restoration for large systems takes such a relatively long time, the present invention provides various degrees of individual file access even as the restoration process is being carried out. During file system restoration times, file access may be full or limited to a file's attributes. Most advantageously, the present invention is capable of providing full, dynamically driven (on-demand) file access even during file system restoration operations.
