A backup that has never been restored is a hope, not a backup. That sentence sounds like a cliche until the day a database gets corrupted and the team discovers the nightly job has been writing empty files for weeks. The pattern is common enough that it deserves to be the starting point for any plan.

Replication Is Not Backup

Cloud services make it easy to confuse two different things. Replication keeps multiple live copies of your data so a hardware failure does not take you down. Backup keeps older, separate versions so you can go back in time. If someone deletes a table, replication faithfully deletes it everywhere within moments. If ransomware encrypts a file share, the encrypted version replicates too.

So ask of every system: if the data were wrongly changed an hour ago, a day ago, a month ago, how would we get the earlier state back?

The 3-2-1 Idea, Adapted for Cloud

The old rule of thumb is three copies of your data, on two different kinds of storage, with one copy kept elsewhere. In a cloud setting, that translates to something like:

• The live data in your primary service.
• A backup in the same provider but under a separate account or with separate permissions, so a compromised everyday login cannot erase it.
• A further copy in a different region, or with a different provider or on-premises storage, for provider-level or account-level disasters.

Many storage services offer versioning and write-once or immutable retention options that prevent deletion for a set period. Features and names differ by provider, so check the current documentation for what is available and how it is billed.

Decide Two Numbers Before You Pick Tools

Two terms drive every design choice:

• Recovery point objective (RPO): how much recent data you can afford to lose. If the answer is “an hour,” a nightly backup is not enough.
• Recovery time objective (RTO): how long you can be down before the damage becomes serious.

Ask the people who use the system, not just the technical team. A bookkeeping tool might tolerate a day of lost entries during a quiet week and zero at month end. Write the numbers down per system, because different systems deserve different treatment and cost.

What to Include (and What People Forget)

Databases and file storage are obvious. The things that surprise teams during a real recovery are usually the surrounding pieces:

• Infrastructure configuration, such as templates or scripts that define networks, servers and permissions.
• Encryption keys and the secrets needed to read the backups at all.
• DNS records, certificates and identity provider settings.
• SaaS data like email, documents and project tools, which many providers treat as your responsibility under a shared-responsibility model. Read your provider’s terms to see what they do and do not retain.
• Documentation for the restore procedure itself, stored somewhere you can reach when your main systems are down.

Backup Plan Checklist

Item	Question to answer	Done when
Inventory	What systems hold data we cannot recreate?	Written list with an owner for each
RPO and RTO	How much loss and downtime can each tolerate?	Numbers agreed with the business side
Separation	Can a stolen admin login delete the backups?	Backups use separate credentials or immutability
Off-site copy	Does one copy survive loss of the region or account?	Second location confirmed
Encryption	Who holds the keys, and are they backed up safely?	Key recovery tested
Monitoring	Who is told when a job fails?	Alerts reach a person, not a dead mailbox
Restore test	When did we last restore for real?	Dated test record

A Hypothetical Restore Test

Imagine a small online shop with a managed database and a storage bucket of product images. Once a quarter, someone creates a fresh, isolated environment, restores last night’s database backup into it, points a test copy of the site at it, and checks that recent orders and images appear. They time the whole thing. The first attempt reveals that the images were never included in the backup job and that nobody remembered where the database password was stored. Both are fixed within a day, long before an actual emergency. The time recorded becomes the team’s honest RTO rather than a guess.

Costs and Retention

Longer retention and more copies cost more storage. Resist the urge to keep everything forever by default. Group data by value: recent, frequently changed data gets frequent backups kept for a short time; slower-changing records get less frequent backups kept longer. Some data is subject to legal retention or deletion rules, which differ by country and industry, so confirm requirements with a qualified advisor rather than guessing.

Also watch for backup sprawl. Old snapshots from retired projects quietly accumulate charges. Tag backups with an owner and an expiry so cleanup is a routine, not an archaeology project.

Automate, Then Verify

Manual backups fail because people get busy. Use the scheduling features of your platform or a well-regarded backup tool, and make sure failures are loud. Then verify in two ways: automated checks that confirm a backup completed and has a plausible size, and periodic human restore tests that confirm the data is usable.

Frequently Asked Questions

Do I still need backups if my cloud provider replicates my data? Yes. Replication protects against hardware failure, not against accidental deletion, corruption or malicious changes, which are copied along with everything else.

How often should I test restores? At least a few times a year for important systems, and after any major change to the setup. More critical systems justify more frequent tests.

Where should I keep the backup encryption keys? Somewhere separate from the backups themselves, with a documented recovery process and more than one trusted person able to access it. If the keys are lost, the backups may be unreadable.

Is syncing a folder to cloud storage the same as a backup? Usually not. Sync tools mirror changes, including deletions and encrypted files. Look for versioning and retention features, or use a dedicated backup approach.

What should I back up first if I have limited time? Start with data you cannot recreate and systems whose loss would stop the business, such as customer records and financial data.

Next Step

List your three most important data sets, write an RPO and RTO beside each, and schedule one test restore into an isolated environment this month. Record how long it took and what broke.
