From smartphones to laptops, we are generating and storing more data than ever. Photos, videos, work files, and creative projects are often irreplaceable. Yet, a large proportion of Australians remain exposed to loss due to device failure, accidental deletion, cloud issues, or cyber incidents.

Today, 31 March 2026, is World Backup Day. Experts are reminding Australians to take a few simple steps to protect their digital lives before something goes wrong.

Real-world cases highlight how easily that data can disappear. Sydney-based creative Fabiana lost three years of photos, including memories from eight months of backpacking through Southeast Asia, after a cloud backup failure.

“I thought everything was safe in the cloud. Then one day it was just gone,” Fabiana said. “I actually sobbed. Those memories are gone forever.”

The 3-2-1 Backup Rule: How to Protect Your Data

Experts recommend following the “3-2-1 rule” when backing up important files:

Keep three copies of your data
Use two different types of storage
Keep one copy in a separate location

For many people, that might mean storing files on their phone or computer, saving a copy in the cloud, and also keeping a backup on a physical device such as a USB drive or external SSD.

Best Tools for Backing Up: iPhone and Laptop Solutions

Backing up important files can be simple.

For example, newer iPhone users, including the iPhone 15 Pro and later models, can transfer photos and videos directly to a SanDisk Phone Drive with USB-C, creating a secure physical copy of their memories while also freeing up space on their device.

For older iPhones, the SanDisk Phone Drive dual-connector with Lightning and USB-C ports make it easy to move files between devices and create a reliable backup.

Laptop users can also back up their files to an external solid-state drive (SSD). SanDisk Extreme Portable SSDs allow users to back up documents, photos, emails and even their entire system, including operating systems, applications and settings. and settings.

The Critical Step: Testing Your Data Recovery

And here is where I step in, putting my business continuity hat back on.

What is more important than backing up your data? Checking that the backup has worked and regularly testing that you can still read the files.

Many users assume they are protected but never attempt a recovery until a crisis occurs. This often leads to the discovery of corrupted files or failed syncs when it is too late.

Incorporate a “restore test” into your routine every season or half-year. Ensuring you can actually retrieve your files is the only way to move from over-confidence to genuine digital security.

 

World Backup Day serves as a reminder to take a few minutes to safeguard what matters most.
