Set mirroring configuration to level-0 backup state

Verify that your current mirroring configuration matches the configuration that was in effect at the time of the last level-0 backup.

The most critical parameters are the mirroring parameters that appear in the configuration file, MIRRORPATH and MIRROROFFSET.
