How to Know If Your Backup System Will Actually Work in an Emergency

By Yiddy Lemmer, CEO – CompuConnect, Inc.

The most reliable way to check whether your business backups will work in an emergency is to run a timed restore test. Have IT recover a critical application and its data in a safe test environment. Then have the employee who uses it sign in, verify a recent record, and finish a normal task. Compare the elapsed time and the age of the recovered data with the limits your business can tolerate.

For a billing manager, the deciding detail might be a credit posted yesterday. If the restored accounting system opens but still shows the customer’s old balance, sending invoices could create a second problem. That single transaction gives you a better check on recovery than a dashboard full of green check marks.

What does your business need back first?

Ask each department lead one question. “If we lost access at 9 a.m. tomorrow, what is the first commitment we would struggle to keep?” You may get a more useful answer than you would from asking for a list of critical software.

A home healthcare agency’s scheduling manager might need the latest shift changes before the morning round of calls. An accounting firm might be able to queue routine bookkeeping for a day, but need its tax software and signed authorizations that afternoon to meet a filing deadline. Even within the same business, recovery priorities can change with the calendar.

Have the operations lead settle the order when two departments both need to go first. Then ask IT what each one depends on. Restoring the tax application may do little for the preparer if the authorizations are in a separate document system or nobody can sign in.

What recovery time and data loss can your business afford?

Set two limits for each priority task. The first is how long staff can wait to resume work. The second is how far back they can go in the data and still catch up. Your IT provider may call these your recovery time objective and recovery point objective.

Suppose payroll is due at noon and the manager needs an hour to review and approve it. An outage at 9 a.m. leaves two hours to get payroll ready for review. Now consider the data. Last night’s backup might include every employee but miss the corrections entered this morning. If those corrections came from saved timesheets, someone can re-enter them. If supervisors called them in, reconstructing the same hour of work could take much longer.

This is where leadership can make a sensible spending decision. Paying for more frequent copies may be worthwhile for payroll during processing hours. For a reference folder that changes twice a month, a longer recovery window may carry little cost.

Which applications and records should your backups cover?

At your next backup review, bring the person who does the work. Have them walk IT through one transaction from start to finish. A billing manager may start in an accounting application, pull an approval from email, and retrieve a signed document from a shared folder. Each step identifies something the team must be able to recover or access another way.

For each system, ask who is responsible for recovery, how far back they can restore, and what staff should do if the usual administrator is unavailable. This is especially important for software managed by an outside provider. Ask the vendor a specific question such as, “If someone deletes a batch of invoices and we discover it three weeks later, which records can you restore, and what happens to the invoices entered since then?” The answer tells you whether recovery itself could create more reconciliation work.

How do you run a backup restore test?

Choose one plausible disruption and give the test a clear finish line. For example, assume the billing server is unavailable on the morning invoices are due. IT should restore the required systems in a separate environment where staff can safely check the results without emailing customers or changing live records.

Start the clock when the simulated outage is reported. Include the time spent reaching the right person, getting approval, restoring data, and giving the billing manager access. Have the manager sign in with ordinary permissions and check something specific, such as an invoice adjusted yesterday. A familiar customer list can look perfectly reasonable even when the latest adjustments are missing.

Write down when the manager could finish the task and what had to be recreated. Keep the conclusion as narrow as the exercise. A successful invoice test gives you evidence about billing under those conditions. Recovering after an office-wide outage may also require replacement computers, internet access, and a way to communicate with staff.

Would a usable copy survive a ransomware incident?

A damaged server and a compromised administrator account present different recovery problems. In the second case, ask whether someone using that account could also change or delete the backups. Ask how IT would identify a copy from before the suspected compromise and where the team could safely examine it before reconnecting systems.

Our practical recommendation is to ask IT to demonstrate how an authorized backup administrator would retrieve that protected copy if the usual company sign-in were unavailable. It’s better to discover during a scheduled exercise that the recovery instructions are sitting on the very server you’re trying to restore.

What should a backup test report tell leadership?

Ask for a short record of the business task tested, the agreed limits, the actual results, and who verified them. If the team missed a target, record where the time went before approving a purchase. Faster backup hardware won’t help much if the longest delay was waiting for someone authorized to contact the software vendor.

Give each gap an owner and a retest date. A payroll manager can verify that the recovered records are usable, while IT can confirm that the technical fix worked.

How often should you test your backups?

Agree on a testing schedule that reflects how often the system changes and what a missed deadline would cost. A move to a new payroll platform, a change in IT providers, or an upcoming busy season can justify testing sooner.

The more consequential the deadline, the more recent you want the evidence to be. If your last test took place before employees switched to a new sign-in system, the old report still documents what worked then. A fresh test tells you whether staff can get back in today.
