You can protect the selected part of the archive from being overwritten. To do this, do the following:

1. Create a new archive (see Creating an archive) and configure on-demand replication for it (see Configuring data replication).
2. Switch to the Archive mode (see Switching to the Archive mode).
3. Specify the time interval on the timeline (see Standard video recordings export). Recordings from this interval are copied to the new archive.
   
4. Click the button .

5. In the Export folder field, select the archive to which the selected recordings will be copied. 
   

   Replication is performed only to the end of the archive. It is not possible to overwrite existing data in the archive. If the selected replication interval is earlier than the end of the mirror archive, replication is impossible (the Export button is unavailable).

6. Click the Export button (2).

Selected recordings are copied to the specified archive.
