Why Your Cloud Needs a Local Backup Plan

We were swapping a hard drive on a client’s office PC when the internet went out and their cloud‑based accounting software froze mid‑invoice. That moment shows why relying on the cloud alone is risky for anyone who can’t afford a lost sale or a missed deadline. Do I really need a local backup if I use Microsoft 365? Short answer: yes. Cloud storage protects against server failures, but it doesn’t guard against your own network dropping out or a provider’s regional outage. Keep a recent copy of critical files on an external drive that you plug in weekly. A 2 TB USB‑3.0 HDD costs about £60 and can be sealed in a fire‑proof safe for extra peace of mind. How can a power cut bring my cloud down? When the mains go, routers, switches and even your Wi‑Fi disappear. Most small‑business broadband modems have no battery backup, so the moment the power flicks, you lose access to cloud services. Installing an uninterruptible power supply (UPS) for your router and key workstations gives you at least 10‑15 minutes to finish a transaction or switch to mobile data. What about network congestion from big events? Air‑traffic strikes or city‑wide festivals can overload local fibre routes, causing latency spikes that make cloud apps feel sluggish or time‑out. Using a wired Ethernet link where possible reduces jitter, and having a secondary 4G/5G dongle as a fail‑over can keep you online when the main line is congested. Is a single cloud provider enough? No. A single point of failure is a recipe f
