For financial institutions,a communication outage can cost millions in lost revenue,regulatory fines,and damaged trust.Whether from a hurricane,cyberattack,or network failure,disaster recovery(DR)plans are critical to keeping systems online.Here’s how to build a resilient strategy.
Layer 1:Redundant Infrastructure
The foundation of DR is redundancy.Deploy active-active systems where two identical setups run simultaneously—like Redstone’s local active-active model for headquarters.If one system fails,the other takes over instantly,with real-time data sync ensuring no loss of calls or recordings.For global banks,geo-redundant setups(e.g.,one site in London,one in New York)add another layer:if a region goes offline,the backup site handles all traffic.
Layer 2:Local Survivability for Branches
Branches are often more vulnerable to outages.Redstone’s EGW50 local survivability gateway acts as a safety net:if the link to headquarters fails,it takes over call control,connecting to local PSTN lines to keep basic voice services(calls,faxes)running.This is critical for rural branches or areas prone to network disruptions.
Layer 3:Power and Network Failover
Even the best systems fail if the power goes out.Redstone’s hybrid devices switch to PSTN during power outages,while dual LAN ports and 4G/wired redundancy ensure network connectivity.For example,Thailand’s S Leasing deployed REX 1000 with dual power supplies—during a regional blackout,their branches stayed online via backup power and 4G.
Layer 4:Secure Data Backup
Recordings and call logs are vital for compliance.Redstone’s NL-Recording system uses dual-active clusters and encrypted off-site backups,ensuring data survives disasters.Recordings are cached locally during outages and auto-uploaded once systems recover—avoiding gaps in compliance.
Layer 5:Regular Testing and Updates
A DR plan is only effective if tested.Schedule quarterly drills to simulate outages(e.g.,server failure,network breach)and refine responses.Redstone’s UMS(Unified Management System)simplifies testing by letting admins simulate failures and monitor recovery times.
By combining these layers,financial institutions create a DR strategy that turns disasters into minor disruptions—protecting operations,compliance,and customer trust.
