Where we work

Supporting businesses across Orange County

Orange County has distinct business hubs, each with its own mix of companies and IT needs. Here's how we help in each.

North County

Fullerton, Anaheim, Brea & Buena Park

Manufacturing, distribution and family-owned businesses along the SR-91 and SR-57 corridors, where a down network can stop orders going out the door.

Central

Irvine Business Complex & Irvine Spectrum

Corporate offices, tech companies and medical device makers. Data backup services for Irvine, CA businesses: encrypted off-site backups, a test restore every month and a recovery plan.

Airport area

Costa Mesa & Newport Beach

Financial advisors, accountants, real estate and professional firms near John Wayne Airport, where client confidentiality comes first.

County seat

Santa Ana, Orange & Tustin

Law firms near the courthouses, plus medical groups around the hospitals in the City of Orange, handling sensitive legal and patient data.

South County

Lake Forest, Mission Viejo & Laguna Hills

Medical practices, business parks and growing companies along the I-5 and SR-241, many close to the wildfire-prone foothills.

Coastal

Huntington Beach & Fountain Valley

Service businesses, contractors and manufacturers near the coast, where planning for outages and earthquakes matters.

Backup & recovery

Backup & Disaster Recovery for Orange County Businesses

If you are looking for data backup services in Irvine, CA, Anaheim or anywhere in Orange County, every Xonicwave plan includes the same protection: encrypted off-site backups, a test restore every month and a plan for getting back to work.

Encrypted, off-site backups

Computers backed up daily and servers twice a day, stored outside the region.

Monthly test restores

Proof every month that your data comes back.

File versions kept 180 days

Up to 10 versions of every file.

Microsoft 365 and Google Workspace backup

Email and files backed up while you are a client.

On-site recovery help

On-site delivery of restored data or a technician at your Orange County office during business hours on Platinum and Titanium; Titanium adds after-hours on-site emergency support. On Gold, we restore remotely, and an on-site visit is available as extra billable hours.

A written recovery plan

For wildfire power shutoffs, earthquakes and ransomware.

Local risks

Orange County risks we plan for

Keeping an Orange County business running means planning for more than hackers.

Wildfires and power shutoffs

Fires like the Silverado Fire in 2020 and the Airport Fire in 2024 forced evacuations near Irvine and the canyons, and Southern California Edison can cut power during high winds.

How we plan for it

Battery backup for key equipment, cloud email and files that work from anywhere, and backups that keep running when the office is closed.

Earthquakes

The Newport-Inglewood Fault runs along the coast through Newport Beach, Costa Mesa and Huntington Beach. It caused the 1933 Long Beach earthquake.

How we plan for it

Encrypted backups stored outside the region, tested restores, and a written recovery plan so you know who does what.

Scams aimed at high-value firms

Medical device makers, healthcare groups and financial firms hold data criminals want, and Orange County has plenty of all three.

How we plan for it

24/7 SOC security monitoring on every plan, multi-factor sign-in, and email protection against phishing.

Coverage

How support works in Orange County

Remote support, every plan

Most issues are fixed over a secure connection, usually while you're still on the phone with us.

On-site visits

A technician comes to your office anywhere in Orange County on our Platinum and Titanium plans.

After-hours help

Titanium adds a 24/7 help desk and on-site emergency help when something can't wait until morning.

Services for Orange County businesses

Serving Orange County

On-site across the county

We serve Orange County from our Southern California team, on-site on Platinum and Titanium and remotely on every plan.
