If an archive is created from an existing volume, it will be possible to extract saved video from the file only if the following conditions are met:

• 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:

1. Create an archive (see Creating a local archive).

2. Select disks or network archives that contain existing volumes (by selecting check boxes, 1).

   

   A new archive can contain volumes that previously belonged to different archives

3. If the volume is in file form, select the archive file to which recording was performed (2).

4. Clear the Formatting check box (3).

   If the Formatting check box is selected, the archive entries that are currently stored on the volume will be erased.

5. If necessary, create new archive volumes on free partitions.

6. Click the Apply button.

The archive is created and, if all requirements are met, the archive recordings are available.
