A NAS is not magic redundancy — it is a convenient box that still needs a second location for true backup.

Canadian households drowning in 4K phone video and scanned tax PDFs eventually outgrow USB drives in a junk drawer. Network-attached storage brings central folders, versioning and media streaming. Done poorly, it becomes a single point of failure humming in a closet. This longread covers hardware sizing, RAID honesty and the off-site habit that matters.

What a NAS is good for

  • Central family file share with user accounts.
  • Phone photo sync targets.
  • Time Machine / Windows backup destinations.
  • Light media streaming to TVs.
  • Private document storage without per-GB cloud anxiety.

It is less ideal as an unattended public-facing server. If you expose services to the internet, use VPN access rather than opening random ports on a consumer ISP connection.

RAID myths Canadians still believe

RAID 1 or RAID 5 is availability, not a backup. It survives a drive failure; it does not survive ransomware, theft, fire or « delete the wrong share » moments. Pair NAS storage with versioning snapshots and an encrypted copy off-site — cloud sync, a drive at a relative's house or a safety-deposit style offline disk rotation.

Sizing and noise

Start with usable capacity for three years of photos plus documents, then add 30 %. Two-bay kits suit apartments; four-bay suits growing libraries. Place the unit where vibration will not annoy — linen closets beat bedroom nightstands. Check wattage; always-on storage adds to Ontario and Alberta electricity bills.

Power outages and UPS

Ice storms and summer storms argue for a small UPS that lets the NAS shut down cleanly. Dirty shutdowns corrupt arrays more often than Hollywood drive explosions. Enable graceful shutdown in the NAS UPS settings.

Security baseline

  1. Change default admin credentials; use unique users per person.
  2. Keep DSM/TrueNAS/etc. updated.
  3. Disable unused apps and public link sharing by default.
  4. Put the NAS on the trusted LAN, not the IoT SSID.
  5. Encrypt sensitive shares; record the key offline.

Ransomware-aware habits

Immutable or snapshot schedules save restorations. Keep one backup target that is disconnected most of the time. Test a restore quarterly — an untested backup is a rumour.

Buy the NAS for convenience, but fund the second and third copies for survival. RAID keeps you working; backups keep you whole.
