Backups & Storage

NAS setup planner

2026-aware NAS platform direction for backups, photos, media, remote access, and drive growth, including the Synology 2025-series transcoding trap.

Use this before buying a NAS, migrating files, opening remote access, or turning one box into the only copy of important data. The 2026 reality: Synology 2025-series Plus lost Plex hardware transcoding, HDD prices are up 46% since Sep 2025, idle wattage compounds to $40-100+/year, and 1GbE is the silent bottleneck for most homes.

High priority

Use the NAS as local storage, then add an offsite backup layer.

A NAS in the house is not a complete backup. Use it as the local layer, then add a copy that survives loss of the home.

First checks

  • Write the job first: backups, photos, media, or mixed home storage.
  • Plan capacity for 4 TB today plus 4 TB growth = 8.0 TB raw target. Leave room for parity + snapshots on top.
  • Decide who maintains updates, alerts, failed backups, and drive warnings.
  • Confirm whether important data has a copy away from the home.
  • Confirm whether 1GbE is your home network's ceiling — the NAS will be link-capped at ~110 MB/s.

Step-by-step troubleshooting

  1. 1

    Define the NAS job

    Write one primary job for day one: backups, photos, media, or mixed storage. Keep optional apps out of the first setup.

    Expected: The platform and drive plan should match the job, not a generic 'best NAS' list.

    Next: Use the platform direction below to choose appliance, guided, or DIY setup comfort.

  2. 2

    Build a pilot before migration

    Create one shared folder, one named user, one test backup or file sync, alerts, and a reserved local IP.

    Expected: The NAS should be discoverable, alerting, and restorable before it holds important originals.

    Next: Run a small restore or file recovery test before copying large libraries.

  3. 3

    Close the safety gaps

    Add offsite backup for the important NAS data before deleting anything from the original computer or drive.

    Expected: A NAS failure, mistaken delete, or loss of the home should not be the end of the data.

    Next: Add UPS protection and configure graceful shutdown before relying on overnight backups.

  4. 4

    Handle remote access last

    Use MFA and VPN-style or vendor-managed remote access. Do not port-forward NAS admin pages directly.

    Expected: Remote access should not weaken the backup and account model you just built.

    Next: If you cannot explain the remote path, leave it off and ask for help.

What your answers suggest

  • Top platform fit for your inputs: **Synology DS923+ (4-bay Plus, non-x25)**. Calmest appliance path with Btrfs snapshots, Hyper Backup, and Synology Photos. DSM 7.3 (Oct 2025) reversed the drive-lock policy so third-party HDDs install cleanly. AMD R1600 means no Plex hardware transcoding — pair with a separate N100 or mini PC if you add a media server later.
  • Plan more usable capacity than today's files (target ~8.0 TB raw with growth). Backups, photos, and media grow quickly.
  • Offsite backup is missing, so the NAS would be only the local layer.
  • UPS is missing for a NAS role that should survive short outages or shut down cleanly.
  • Idle electricity at the top recommendation tier: ~18 W × 24 h × 365 d × $0.16/kWh ≈ **$25/year**.
  • Link speed (1GBE) is adequate for the workload as described.

Likely cause area

  • Top platform fit for your inputs: **Synology DS923+ (4-bay Plus, non-x25)**. Calmest appliance path with Btrfs snapshots, Hyper Backup, and Synology Photos.

  • Plan more usable capacity than today's files (target ~8.0 TB raw with growth). Backups, photos, and media grow quickly.
  • Family use usually benefits from simple accounts, clear shared folders, and fewer experimental services.
  • Backup reliability depends on restore tests, not just a green schedule.
  • A NAS used for backups or larger storage should be protected by a UPS.
  • Alternative platform: **Mac mini M4 + external SSD + Time Machine (light NAS)**. Best-in-class power profile (~12W idle for the whole stack including SSD). Time Machine destinations work cleanly; macOS SMB has known socket-limit quirks for Plex though. Realistic role: lightweight file/Time Machine target + media server, not a primary multi-bay storage box.

Safe actions

  • Create one test share and one test backup before moving everything.
  • Use a reserved local IP address and named user accounts.
  • Add cloud or another offsite copy before deleting original files. See /guides/home-backup-3-2-1-nas-cloud-usb for the 3-2-1 layered plan.
  • Use VPN-style or vendor-managed remote access with MFA; avoid direct port forwarding. See /guides/home-remote-access-tailscale-vs-cloudflare-tunnel for the Tailscale vs Cloudflare Tunnel decision.
  • Schedule snapshots on the candidate platform (Btrfs on Synology, ZFS on TrueNAS/Unraid 7, snapshots on QTS) with 14-30 day retention before going live.

When to stop

  • Stop before exposing admin panels or file shares directly to the internet.
  • Stop before formatting, rebuilding, or deleting old storage during migration.
  • Stop if a drive reports failure and the NAS holds the only copy.

Assumptions

  • Assumes home/home-office use, not regulated business storage.
  • Exact model choice needs current product research and your tolerance for maintenance.
  • Platform recommendations reflect May 2026 reality: DSM 7.3 drive-lock reversal (Oct 2025), Synology 2025-series Plus i915 driver removal still unfixed, QNAP TS-x64 line as the appliance-with-Quick-Sync answer, TrueNAS Scale Goldeye 25.10.x as current stable, Unraid 7.x with ZFS support, Mac mini M4 as low-power appliance niche.

What should I check first?

  • Decide the NAS job first: backups, photos, media, or mixed storage.
  • Estimate today's data size plus 3-5 year growth before choosing bay count or drives — undersizing is the second-biggest 2026 trap.
  • Check whether important data already has an offsite copy.
  • Decide whether Plex / Jellyfin hardware transcoding matters — this single answer eliminates the Synology 2025-series Plus from the recommendation list.
  • Confirm your home network link speed — 1GbE caps useful NAS throughput at ~110 MB/s regardless of internal storage.

What is likely wrong?

  • A NAS is being treated as a complete backup plan instead of the local layer.
  • Remote access or media apps are being planned before basic storage, accounts, alerts, and restore checks.
  • Platform choice is being made from brand reputation instead of maintenance comfort.
  • Synology 2025-series Plus (DS425+/DS725+/DS925+/DS1525+/DS1825+) is on the shortlist for a Plex setup — Synology stripped the i915 kernel driver from DSM, so the Intel iGPU is present but Quick Sync is inaccessible. Community SSH workarounds exist but break on reboot.
  • 1GbE is being kept for a media + multi-user workload — the single most under-appreciated NAS bottleneck.
  • Idle wattage is being ignored — a 60W box vs 20W box compounds to $70+/year at US rates, $130+ at UK/EU rates.

What is safe to try?

  • Create a test share and one test backup before migration.
  • Use a reserved local IP, named users, and platform alerts.
  • Prefer VPN-style or vendor-managed remote access with MFA over direct port forwarding.
  • Schedule snapshots on day one (Btrfs on Synology, ZFS on TrueNAS / Unraid 7, snapshots on QTS) with 14-30 day retention — separate from off-box backup, but the first line of defense against accidental delete and ransomware.
  • For 14 TB+ drives in 2026, plan recertified-vendor purchases (ServerPartDeals / GoHardDrive) with `smartctl -l farm` on-arrival verification — the 2025 Seagate FARM scandal expanded to IronWolf Pro in late 2025.

When should I stop?

  • You are about to format, rebuild, or wipe a drive that may hold the only copy.
  • The NAS reports degraded storage, failed disks, or rebuild errors.
  • Remote access requires opening ports you do not understand.
  • You are about to buy a Synology 2025-series Plus with Plex / Jellyfin hardware transcoding in scope — pick QNAP TS-464 / TS-664 or an N100 mini PC instead.
  • You are about to commit to a 1GbE link for a media or multi-user workload — bump the switch first.
