Separate the copies
A backup should not depend on the same device, credentials and location as the original data.
A real backup and disaster-recovery setup keeps independent copies that can be restored after hardware failure, deletion, theft or attack. A NAS can be one layer, but it is not the whole plan. In Australia, offsite location, upload speed and recovery practicality matter. If you are starting from scratch, see our backup-focused NAS buying guide.
This hub is for readers who own or are considering a NAS and want to know whether their backup strategy provides meaningful protection.
A sound plan separates everyday storage from recovery copies and considers how those copies would perform during a real incident.
A backup should not depend on the same device, credentials and location as the original data.
An offsite copy protects against incidents that can affect both a NAS and nearby local backups.
A completed backup job is useful only if the required files can be restored when needed.
Start with the situation that most closely describes what is missing or uncertain in your current setup.
Begin with the core backup strategy before choosing products, services or detailed settings.
Compare tools according to your devices, destinations, scheduling needs and expected recovery workflow.
Assess storage, transfer and recovery requirements before committing important data to an offsite service.
Add isolation, protected recovery points and restore testing instead of relying only on ordinary shared folders.
If you are still planning capacity, size your storage needs before choosing hardware and retention settings.
Estimate storage needs before you choose hardware and backup retention settings.

Need to Know IT uses a documented evaluation process, cross-checks claims against official documentation and keeps guides updated for Australian pricing and availability.
There are no sponsored rankings and no paid placements in editorial recommendations.
Advice is framed around the products, prices, retailers and risks Australian buyers encounter.
Product and software claims are cross-checked against vendor documentation rather than repeated from listings.
Guides in this hub are revisited as products, prices and the underlying decision-stage taxonomy change.

No. RAID is primarily an availability feature: depending on the configuration, it may allow storage to continue operating after a drive failure. It does not protect against every hardware failure, accidental deletion, theft, fire or ransomware. Read why RAID is not a backup before designing your recovery plan.
You need an independent offsite copy, but it does not necessarily have to be cloud storage. A remote NAS or appropriately managed removable storage may also fill that role. The NAS-to-cloud backup guide and hybrid NAS and cloud guide explain the practical choices.
There is no single figure that fits every dataset or provider. Check storage charges, retention, retrieval or egress conditions, transaction fees and the amount of data you may need to recover. Use the Australian cloud backup cost guide, provider comparison and NBN upload-time guide for the detailed calculation.
The 3-2-1 approach means keeping three copies of your data across two storage types, with one copy offsite. That is the starting structure, not a guarantee by itself; retention and restore testing still matter. See the full 3-2-1 backup strategy guide, then use the NAS backup software comparison to choose an implementation.
Separate backup access from everyday accounts, retain multiple recovery points and test clean restores. An immutable backup is a copy that cannot be altered or deleted during a defined retention period, which can provide another protected recovery layer when configured correctly. Continue with the NAS ransomware protection guide and immutable backup explainer.
