Why Backup Alone Is Not Enough When Things Go Wrong

"We have backups."

It is one of the most reassuring things an IT team can say after a company has invested in protecting its systems.

We know that a copy of our data exists somewhere, but having a backup does not tell us how quickly we can restore our systems, whether the backup is usable, which systems should be restored first and whether the recovery process will work as expected.

That difference becomes particularly important during a serious incident such as ransomware.

When systems are compromised, we shift from having something to restore to bringing critical systems back into operation.

A backup is a starting point, not a recovery plan

Imagine that your main systems become unavailable today.

Maybe you have a backup from last night. That sounds reassuring. But if restoring the environment takes two days, the existence of that backup does not tell you whether the recovery plan is good enough.

How much data can we afford to lose?

This is the Recovery Point Objective (RPO), the point in time to which data needs to be recoverable. If your RPO is four hours, for example, losing the last four hours of data may be within the agreed tolerance. If it is fifteen minutes, your recovery strategy needs to provide a much more recent copy.

How quickly do we need the system back?

This is the Recovery Time Objective (RTO), the target time for restoring a system or service after an incident.

| These are two critical business decisions that depend on how important a system is and what happens if it remains unavailable.

Recovery needs to be designed

A recovery strategy involves different technologies and approaches depending on the business.

Backups may be enough for some systems. Others may require replication, where a more recent copy of a system or its data is maintained in another environment. Critical workloads may need a Disaster Recovery (DR) environment that allows systems to be restored or failed over, when the primary environment is unavailable.

Is the recovery process designed around the systems you depend on?

A company may have excellent backups but still discover during an incident that nobody knows which server should be restored first, that credentials are unavailable, or that a critical dependency was overlooked.

This is where recovery testing shows its value. A recovery plan that has never been tested is still an assumption.

The cloud is not the recovery strategy

Cloud infrastructure can be an important part of a disaster recovery strategy. It can provide flexibility around infrastructure, replication and recovery environments.

Running systems in the cloud does not automatically mean that those systems can be recovered quickly. The same questions still apply.

- Where is the backup?
- How recent is it?
- Who manages it?
- What happens if the primary environment is unavailable?
- How is recovery initiated?
- When was the process last tested?

Depending on the recovery requirements of the business, the answer is either Cloud infrastructure, on-premise infrastructure, a combination of both (Hybrid Cloud), or a managed environment.

"The systems are down. What do we do now?"

At this point, the conversation around backup starts to shift towards recovery. Having a backup gives you something to work with. What happens next depends on the infrastructure, the recovery process, the people responsible for it and how prepared they are to use it.

If your main systems were unavailable tomorrow, would your team know exactly where to start?
