A destination storage server, which may be a filer, mirrors a volume
managed by a source storage server, which may also be a filer. According
to an embodiment of the invention, changes made to the source volume are
logged and persistently stored on a data container, such as a file, on
the destination volume. The source storage server is coupled to clients
that make data access requests to the volume. When an access request is
made by a client, the request is written to a log on the source storage
server. At the same time, the request is written to a data container on a
volume managed by the destination storage server. Each source storage
server coupled to the destination storage server has its own file on the
volume.
