High Availability & Disaster Recovery
Failover, replication, and recovery plans built for the outage you hope never happens — tested before it does, not during.
FCS High Availability & DR, End to End
From business impact analysis to continuous monitoring — everything we cover under HA & Disaster Recovery.
What's covered
Business impact & RTO/RPO planning
Defining how much downtime and data loss is actually acceptable, system by system.
Failover architecture
Active-active or active-passive setups matched to what each application actually needs.
Replication across sites
Data kept current between primary and standby environments, on-premises or cloud.
DR drills & runbooks
Documented recovery steps tested on a schedule, not discovered during a real outage.
Standby infrastructure
Rented or owned failover hardware kept ready through IT Rental Solutions.
At a glance
The right call when an hour of downtime has a real, calculable cost.
How an engagement runs
Define recovery objectives
Set target RTO/RPO per system, based on real business impact rather than a blanket policy.
Build & replicate
Stand up failover infrastructure and replication between sites.
Test & maintain
Scheduled DR drills that keep the runbook honest as systems change.
Frequently asked questions
What's the difference between high availability and disaster recovery?
High availability keeps a system running through component failures — a disk, a node, a single server — usually with automatic failover and no data loss. Disaster recovery covers larger-scale events — a site outage, regional failure, or corruption — and involves restoring service from a separate location, typically with some recovery time and a defined data-loss window.
How much does HA/DR cost to implement?
It depends entirely on your recovery objectives — a warm standby with a few hours of acceptable downtime costs far less than near-zero RTO across regions. We size the architecture (and the cost) to the RTO/RPO your business actually needs, not the most expensive option available.
How often should we test our disaster recovery plan?
At minimum twice a year, and after any significant infrastructure change. A DR plan that hasn't been drilled recently is a guess, not a plan — most failures we see in DR come from environment drift since the last real test.
What RTO/RPO can you realistically achieve?
It depends on your architecture and budget — near-zero RTO/RPO is achievable with synchronous multi-region replication, while a cost-conscious setup might target hours instead of seconds. We help you set numbers based on what an outage actually costs your business, then design to hit them.
