Home Backup Australia — Complete Guide to Protecting Your Files
Most Australian households have no working backup. Photos are on a phone with no copy elsewhere. The family PC has files that haven't been backed up in years. A single hard drive failure, theft, or house fire ends years of irreplaceable memories. This guide covers the practical options — what a NAS actually does, how it fits into a home backup plan, and which setup makes sense for your situation — without assuming any technical knowledge.

The simplest reliable setup is a 2-bay NAS with two matching drives in RAID 1 (mirroring) connected to your home router, plus an automatic cloud backup to cover you if the NAS is lost or damaged. On a Synology NAS, Hyper Backup handles the cloud side automatically. You set it up once and it runs nightly. For Macs, Time Machine backs up to the NAS over your home network without any extra software. For Windows PCs, Synology Active Backup or a mapped network drive works the same way. Total cost: AU $800-1,000 for a Synology DS225+ with two 4TB WD Red Plus drives. Less per year than iCloud 2TB for a household of four.
Safer in some ways, not others. A NAS with RAID 1 protects against a single drive failure. One drive dies and your photos are fine. But a NAS can be stolen, flooded, or catch fire along with everything else in your home. iCloud and Google Photos protect against physical loss and are fully automatic, but you pay monthly and you're trusting a third party with your data indefinitely. The recommended approach is both: keep photos on the NAS (faster, no storage caps, full control) AND back up the NAS to cloud storage like Backblaze B2. Around AU $3-5/month for a typical photo library. That covers physical loss and drive failure simultaneously.
A NAS connects via an Ethernet cable to your router or a network switch. Not to Wi-Fi directly (Wi-Fi is too unreliable for a storage device). Once plugged in, you access it from any device on your home network: a browser on your PC, the Synology DS File or Photos app on your phone, or as a mapped network drive in Windows Explorer or Mac Finder. Initial setup takes about 30-45 minutes following Synology's guided DSM installer. You do not need to be technical. It walks you through creating volumes, setting up RAID, and enabling apps step by step. The Synology Photos mobile app installs on your phone and backs up automatically in the background whenever you're home on Wi-Fi, same as iCloud.
The 3-2-1 rule means: 3 copies of your data, on 2 different types of storage, with 1 copy kept offsite. For a home user it translates to: your original files on a PC or phone (copy 1), backed up to a NAS at home (copy 2, different storage), plus the NAS backed up to cloud storage (copy 3, offsite). It sounds complicated but it is just two backup steps instead of one. The most common failure of home backup is having two copies of everything on the same physical shelf. So a burglary, fire, or flood takes out both at once. The cloud copy exists precisely for that scenario. You do not need to follow the rule exactly, but having at least one copy offsite (even an external drive at a relative's house) dramatically improves your protection.
