The answer depends on the purpose. For example, if the purpose is simply backup (no "use" of the data), then that would be one solution. But if the purpose is for "use" of the data, then it further depends on exactly what the desired "use" is (read only, migrate elsewhere, etc.).
So please clarify exactly what you desire to accomplish and I'm sure we can guide you in a good direction.
