• The name of the computer on which the recording was written to the existing archive volume is the same as the name of the current computer.
• The IDs of the video cameras from which the recordings were written to the existing archive volume are the same as the IDs of the current video cameras.

To create an archive based on an existing volume:

      If you select Yes, all saved video on the volume will be erased
