Schedule automatic backups on a Synology NAS

A Synology NAS can turn a spare drive or second enclosure into a safeguard against accidental deletion, hardware failure and ransomware. The goal is not merely copying files; it is creating a repeatable copy that continues without manual reminders.

Scheduling backups removes the need for a weekly manual sync check. A task that runs overnight can capture quiet changes, while versioning preserves earlier versions when a document is overwritten or encrypted by an attacker.

For Australian homes and small offices in Sydney, Melbourne and regional towns, an attached or local NAS can keep working during an NBN outage. Power loss remains a separate issue, especially where summer storms or bushfire disruptions affect mains electricity.

The practical method uses Synology’s Hyper Backup package. It supports scheduled jobs, retention controls and encryption, and it can send data to removable storage, another Synology or supported cloud storage.

Choose where the second copy lives

Start by matching the destination to the recovery goal. A local target protects against mistakes and ransomware; an offsite copy also survives theft, fire or damage to the NAS.

Destination	Best use	Outage availability	Main caution
USB drive	Low-cost local recovery	Works without internet	Needs safe disconnection
Second Synology	Continuous management	Works without internet	Vulnerable to shared-site incidents
Cloud storage	Offsite recovery	Requires internet	Recurring subscription costs

A USB disk is inexpensive but needs safe disconnection and may require a paused job to resume after reconnection. Models sold through Australian electronics retailers vary in bay count and expansion, so compare capacity with this Synology NAS model guide. A second Synology is easier to manage continuously, while cloud storage depends on provider availability.

Install and start Hyper Backup

In DSM, open Package Center, install Hyper Backup, then launch it and choose Create Backup Task. Follow the wizard to select USB, another Synology NAS or a supported cloud service, and give the destination a clear name.

For a remote Synology, create a dedicated backup account with access only to its destination. Enable transfer encryption and store the recovery key separately from the NAS; losing that key can make an encrypted backup unusable.

Select the data worth protecting

Select the shared folders containing family photographs, client records, documents and other irreplaceable data. Exclude caches and temporary folders to save space, but check exclusions so an important directory is not omitted by habit.

Synology packages may store configuration or databases outside ordinary shared folders. Some applications provide their own export tools, so include supported package data or database exports rather than assuming every visible file has been protected.

Set timing and retention

Set a daily schedule for frequently changed folders, such as 1:30 a.m. local time, and a weekly schedule for slower archives. DSM follows the NAS time zone, so Melbourne daylight-saving changes matter; verify the job after each shift.

Choose smart recycle or fixed versioning rather than keeping unlimited copies. Test the retention period against available storage, enable a post-backup integrity check where offered, and record the expected duration and exit status for review.

Add independent protection

An attached disk protects against deletion but can still be affected by the same power surge, theft or ransomware event. In areas prone to short outages, enable a short UPS shutdown and safe network restart so the NAS and USB target shut down cleanly.

For offsite protection, use another location or encrypted cloud storage, following the 3-2-1 principle of three copies, two media types and one separate site. Snapshot Replication can block rapid deletion when configured appropriately, but it complements scheduled backups rather than replacing an independent restore copy.

Verify recovery and Australian obligations

A backup succeeds only after a test restore. Each quarter, restore a small folder to a temporary location and confirm file size, permissions, application compatibility and the age of the newest version; document any gap before the next job.

For an Australian business covered by the Privacy Act 1988, Australian Privacy Principles require reasonable security controls, including controls against unauthorised access and loss. A NAS helps meet those duties, but backup settings, access rights and retention must match the business’s records policy.

A short recording of the restore process can train staff without adding sensitive material to the video. The business video service can turn approved workflow footage into a polished internal explainer.

A dependable backup rhythm

Monitor job history for changed duration, failed destinations and suspiciously small transfers. Test the restoration procedure whenever the NAS, DSM version, network route or backup policy changes, not just on the quarterly calendar.

The point to remember is simple: a scheduled copy, a protected earlier version and a successful restore provide resilience. A Synology NAS is truly protected only when the backup continues independently and can be recovered when needed.
