Backup Best Practices

A server that crashes on a Friday night, ransomware encrypting the network share, an employee accidentally deleting an entire client folder — in an SMB, the question is never really "if," it's "when." Every company has a different reality, which is why it's essential to define your actual needs before building a backup strategy — without forgetting the disaster recovery strategy that goes with it.

What is a backup, exactly

A backup is, essentially, a copy of your data, kept somewhere other than the original system. That sounds obvious, but it's exactly where many SMBs get it wrong: a duplicated folder on the same server, or a copy on an external drive that stays permanently plugged in at the office, isn't really protection. If the incident hits the original location, it often takes the copy down with it.

Why you actually need one

If your data is lost or deleted and it isn't copied somewhere else, that means: gone, bye-bye. Nobody can guarantee the recovery of data that doesn't exist anywhere else, no matter what the latest trendy tool promises.

And the consequences go well beyond a technical inconvenience. If that data is essential to business continuity, losing it can lead to reputational harm, fines, legal problems, and customer loss. It's not always possible to recreate what's gone — a client database, a project history, accounting records. And even when it is possible, it can represent several days, or even several weeks, of lost wages. Redoing all the work adds to that lost time, on top of draining resources that matter: employees' time, energy, and availability, which could have gone toward anything other than rebuilding something that already existed.

How to build a backup plan that actually meets your business needs

### Define your RPO and RTO

Two simple questions are enough to frame a serious backup strategy.

The Recovery Point Objective (RPO) determines the point from which a recovery can be carried out. In practical terms: how much data are you willing to lose? An hour's worth? A day's worth?

The Recovery Time Objective (RTO) determines the maximum acceptable duration to ensure recovery. In other words: how long can you go without this data before it becomes critical for the business?

To answer these two questions properly, you need to map out your dependencies: identity management systems, databases, business applications. RPO and RTO are directly tied to each application and each system — they're not uniform across the board. Some data is essential to business continuity from the first hour of disruption. Other data can wait a day or two without major consequences. Making that distinction keeps you from paying for maximum protection everywhere, or worse, discovering after the fact that a critical piece of data wasn't protected enough.

### The foolproof method: 3-2-1-0

A simple, proven rule underpins most solid backup strategies: three copies of your data, on two different types of media, with one copy offsite — and zero errors when you test your restores. A backup you've never tested isn't really a backup, it's a hope.

A tailored strategy, not a one-size-fits-all solution

To sum up, protecting against data loss comes down to three pieces that work together:

• Setting up a functional backup that gets tested regularly
• A plan for high availability, to limit interruptions
• A disaster recovery plan, to define what happens if the worst does happen

A backup strategy should be part of the contingency plan of every company, regardless of its size, location, or industry. This isn't an expense reserved for large enterprises — it's a matter of operational survival, within reach of any organization willing to take the time to plan it properly.
