The distributed architecture provides high redundancy levels for partial system failure
Etere provides Disaster Recovery capability to avoid broadcasting interruptions in case of entire site crash
The disaster recovery capability is embedded in Etere solution

5. Replica
SQL replication relies on Etere special process this is part of F90
The Video replication use the scheduling for priority.
Video replication is configured via Workflow
The two systems can have different size
The WAN connection has to be fast enough to allow the video transfer

6. ETERE advantages The 2 sites can have different size
The WAN connection can have any speed
If one item is missing the transfer skips to the next one
Intelligent secondary site deletion avoids repetitive item transfer
The Replica is based on multiple channels
A single transfer handles multiple play-list

7. ETERE advantages Just one connection for both video and data
Fully independent Ds site
Ds sites may have no management
The DS site can have its own archive system

8. Video and archive Disaster recovery Replica on scheduling Main server
