Business Continuity and Disaster Recovery: The Northern Beaches Edition
Because “we’ll figure it out when it happens” isn’t a plan
Published by All IT Services | March 2026
The Northern Beaches is a brilliant place to run a business. Until it isn’t.
If you operate a business on Sydney’s Northern Beaches — from Manly through to Dee Why, Brookvale, Mona Vale, and beyond — you already know the upsides. Great lifestyle, strong local economy, loyal customer base, and a genuine sense of community.
But you also know the downsides that come with the geography. Summer storms that knock out power for hours. Flash flooding that turns Pittwater Road into a river. NBN outages that seem to hit at the worst possible time. And the occasional king tide that reminds everyone that “waterfront” comes with fine print.
None of these are hypothetical. They happen every year. And every year, businesses on the Northern Beaches lose money, lose data, and lose time because they didn’t have a plan for when things go sideways.
Why disaster recovery matters more than you think
Business continuity planning (BCP) is about keeping your business operating during a disruption. Disaster recovery (DR) focuses specifically on getting your IT systems back up. Together, they answer two simple questions:
How long can you afford to be down? This is your Recovery Time Objective (RTO).
How much data can you afford to lose? This is your Recovery Point Objective (RPO).
A business turning over $2 million annually generates roughly $7,700 in revenue per business day. Three days of downtime: over $23,000 in direct revenue impact. For a $5 million business: roughly $19,200 per day. Five days: $96,000.
Risks specific to the Northern Beaches
Severe weather and power outages
The Northern Beaches cop the full force of east coast lows and summer storms. Ausgrid’s outage data consistently shows the area as one of Sydney’s more frequently affected during severe weather. A prolonged outage takes down servers, network equipment, phones, and internet.
Mitigation: UPS on critical systems for graceful shutdown. For zero-downtime businesses, a generator or cloud-first infrastructure eliminates local power dependency.
NBN reliability
NBN reliability on the Northern Beaches is variable. For businesses depending on cloud apps, VoIP, and EFTPOS, an NBN outage is functionally the same as a power outage — everything stops.
Mitigation: A 4G/5G failover connection provides automatic backup. For mission-critical businesses, a second wired connection from a different provider. SD-WAN manages failover automatically.
Flooding and water damage
Parts of the Northern Beaches — Narrabeen, Dee Why, low-lying Brookvale — are flood-prone during heavy rain. A server room at ground level in a flood-prone area is one weather event away from expensive hardware replacement.
Mitigation: Replicate critical data to the cloud in real time. Better still, move primary workloads to cloud infrastructure entirely.
Geographic isolation during major events
When Wakehurst Parkway floods (multiple times a year) or the Spit Bridge gets stuck, staff can’t get to the office and IT support can’t get to you.
Mitigation: Remote work capability — laptops, cloud applications, VPN or zero-trust access. A local disruption doesn’t have to mean a business disruption.
Building a practical DR plan
1. Identify your critical systems
Email and communication, line-of-business applications, file storage, and internet connectivity.
2. Define your RTO and RPO
Be realistic. Email: RTO 1 hour. Accounting: RTO 4 hours. File storage: RTO 2 hours, RPO 1 hour. Phone system: RTO 1 hour.
3. Implement the 3-2-1 backup rule
3 copies of your data, 2 different storage media/locations, 1 copy offsite or offline. The ACSC recommends at least one backup stored offline or immutable to protect against ransomware.
4. Test your backups
A backup that hasn’t been tested is a hope, not a plan. Test restoration quarterly. Run a full DR test annually.
5. Document and communicate
Keep copies of the DR plan in the cloud, on the MD’s phone, and in a printed location. Include IT provider contacts, key staff details, step-by-step procedures, credentials (in a password manager), and insurance details.
6. Review annually
Your business changes. Your technology changes. Your risks change.
Cloud-first: the Northern Beaches advantage
When email runs in Microsoft 365, files live in SharePoint, accounting is in Xero, and line-of-business apps are cloud-hosted, you’ve eliminated dependency on physical hardware.
A flood in Brookvale? Data is safe in Microsoft’s Sydney data centre. Power outage in Dee Why? Team works from home on laptops. Wakehurst Parkway underwater again? Business as usual from the kitchen table.
The bottom line
The Northern Beaches’ unique combination of weather exposure, NBN variability, and geographic access constraints makes DR more important here than in most parts of Sydney. A well-configured cloud infrastructure, a robust backup strategy, a tested plan, and a reliable IT partner — that’s the recipe.
