| Zusammenfassung: | Methods of operating a computer storage system where an identical copy of a mirror source filesystem is maintained on a mirror destination storage volume managed by a mirror destination server. A modification to the mirror source filesystem is planned and executed, and a corresponding change to the mirror destination filesystem is accomplished by storing data directly to the mirror destination storage volume, bypassing filesystem logic that interprets the data stored on the volume. Systems that implement these methods are also described. |
