A method and apparatus for reverting a resource to a prior state in time
is provided. Changes are committed to a resource at a particular point in
time. After the particular point in time, a request, which may be a file
system operation request, to revert the resource to a state prior to the
particular point in time is received at a database server. In response to
the request, the resource is reverted to the state prior to the
particular point in time. The current state of the resource ceases to
reflect the plurality of changes. Advantageously, if a requestor creates
an incorrect version of a resource, the changes made to a schema-based
resource are not compatible with the schema, or the changes of multiple
requesters are not compatible with each other, the resource may be
reverted to the earlier point in time.
