If the N main Servers + standby server operation scheme is in use (see the figures below), it is impossible to create a unified archive. In this case the main Servers perform recording on different logical drives (sections, partitions), local or network. If these drives are specified for archive recording on the standby Server, then the archives from different main Servers will mix.

The AxxonPlayer.exe utility can be used to access the archive created by the standby Server on NAS or local drive (see The Axxon Player utility for viewing and converting the video archive). Alternatively, the main and backup Server archives can be synchronized through the Backup archive module (see Configuring archive synchronization of main and backup Servers).

...

Any Server can act both as a main and as a standby at the same time given that the performance of the Server platform allows it. Therefore, a Failover system can be organized with two video servers that are standby in relation to each other.
As in the cases described above, if both Servers record the archive to the network storage, access to the archive is available when the configuration is transferred. If the Servers record a local archive or use different network storages, the AxxonPlayer.exe utility (see The Axxon Player utility for viewing and converting the video archive) or synchronization through the Backup archive module (see Configuring archive synchronization of main and backup Servers) can be used to access the archive created by a the standby Server on NAS or on local drive.

If the quantity of cameras is bound to specific Servers in the security key, then the license becomes invalid when cameras are moved to the backup Server. In this case the system gives 50 days to restore the faulty failed Server in order to move the cameras back and the license to become valid again. Otherwise, Intellect will unload on the backup Server because the hardware limit is exceeded (see Features of the Intellect software operation when the object limit is exceeded). The time (in days) remaining for restoring the main Server is displayed on the settings panel of the Failover service object:
