What is Backup and Recovery?
Backup and recovery is the systematic copying of an application's data and configuration so it can be restored after loss. Backups protect against hardware failure, human error, corruption and attacks, and recovery is the process of bringing a system back from those copies.
What is backup and recovery?
Backup and recovery is the discipline of regularly copying an application's data and configuration to a safe location, and being able to restore from those copies when something goes wrong. A backup is the copy; recovery is the act of bringing a system back using it. Together they are the safety net that protects a product against the many ways data can be lost: a failed disk, a deleted database, corrupted files, a faulty deployment, or a ransomware attack.
Backups are only as good as your ability to restore from them. A copy that has never been tested is a hope, not a safeguard, which is why recovery is as much a part of the practise as the backup itself.
Why does backup and recovery matter?
For most digital products, data is the business. Losing it can mean losing customer records, transactions, content built over years - sometimes irrecoverably. Beyond the data itself, downtime while recovering costs revenue and erodes trust. A sound backup and recovery strategy turns a potential catastrophe into a manageable incident, and it is increasingly a compliance and contractual requirement, not merely good practise.
What does a backup strategy include?
A robust strategy answers how, where and how often:
- Frequency - how often backups run, driven by how much data you can afford to lose.
- Retention - how long copies are kept, and how many versions.
- Location - copies held in separate places, including off-site or another region.
- Automation - backups that run on a schedule without manual effort.
- Restore testing - regularly proving that recovery actually works.
What are backup best practices?
A widely used guideline is the 3-2-1 rule: keep at least three copies of data, on two different types of media, with one copy off-site. Automate backups so they are never forgotten, and encrypt them so a stolen backup does not become a breach. Crucially, test restores regularly - the moment to discover a backup is unusable is not during a real outage. Define your recovery objectives explicitly: how much data loss is tolerable, and how quickly the system must be back.
How PixelForce approaches backup and recovery
At PixelForce, resilience is designed in from the start rather than added after an incident. Our in-house Adelaide team configures automated, tested backups as part of Phase 2 - Development, QA and Release, and maintains them through Phase 3 - Post Launch Support. This is part of how we hold 99.99% uptime across 100+ shipped products, including platforms handling large volumes of sensitive transactions such as EzLicence. Backup and recovery is delivered through our aws devops consulting, and the ongoing assurance that backups stay current and restorable is part of our app maintenance and support services.

Frequently asked questions
A backup is a copy of data you can restore from. Disaster recovery is the broader plan and capability for restoring whole systems and operations after a major disruption, of which backups are one part. Disaster recovery also covers infrastructure failover, recovery procedures, defined time objectives and the people involved. In short, backups protect data; disaster recovery restores the entire service.
It depends on how much data loss the business can tolerate, known as the recovery point objective. A product processing constant transactions may need near-continuous backups so that at most minutes of data are at risk, while a slowly changing system might back up daily. The principle is to set the frequency by the cost of the data you would lose between backups, not by convenience.
The 3-2-1 rule is a simple, durable guideline: keep at least three copies of your data, store them on two different types of media, and keep one copy off-site or in a separate location. This protects against single points of failure - a disk dying, a site outage, or an attack reaching your primary systems. It remains a sound baseline even with modern cloud backups.
Because a backup that cannot be restored is worthless, and failures are common: incomplete copies, corrupted files, missing configuration or processes nobody has rehearsed. The only way to know recovery works is to perform it regularly in a controlled way and confirm the system comes back correctly. Testing also measures how long recovery takes, so expectations match reality during a genuine incident.
