Forechannel connections are established from client-side deduplication libraries at clients to a data protection appliance having a server to be upgraded. The client-side libraries receive requests from backup applications at the clients for file data. The forechannel connections are responsible for carrying the file data between the client-side libraries and the appliance. Server-initiated connections are established from the server to the client-side libraries. The server-initiated connections are responsible for carrying instructions from the server to the client-side libraries. While a transfer of the file data is in progress, the client-side libraries are instructed over the server-initiated connections to pause the transfer for the server upgrade. Requests from the backup applications are allowed to continue uninterrupted. After the server has been upgraded, the forechannel and server-initiated connections are re-established.

The present disclosure provides a system (102) and method (500) for ensuring service continuity in a network (108) through automatic switchover to one or more backup nodes (304) upon detection of database failure. The method (500) involves continuously monitoring health parameters of a first database (210A) associated with a primary node (304A) to detect anomalies or failures. Once a failure is identified, a switchover request is transmitted to the backup nodes (304) for evaluation. Each backup node determines the availability of its associated database (210) and, upon confirming readiness, transmits a notification to a processing engine (208). In response to the notification, the processing engine initiates an automatic switchover by updating one or more attributes of the selected backup node (304), thereby promoting it to an active operational role. This seamless transition ensures uninterrupted network performance, eliminates manual intervention, and enhances fault tolerance and system resilience against database outages.
