Data loss is statistics, not fate
A modern SSD has an average lifespan of 5–7 years under permanent use. An HDD 4–5 years. A USB stick even less. Smartphone storage rarely outlives the device. If you have photos only on one device, you'll lose them sooner or later, guaranteed.
The IT world's answer since the '80s is the 3-2-1 rule: three copies of the data, on two different media types, one of them offsite. The rule is still the standard in 2026 — but the implementation has changed.
The 3-2-1 rule modernized
- Copy 1 — the working set. On the main device (laptop, iPhone), used daily.
- Copy 2 — the local backup. An external SSD/HDD or a NAS in the house. Automated via Time Machine, Synology Drive, or similar solutions.
- Copy 3 — offsite. In a cloud, at a friend's, or in another physical location. Protects against house fires, theft, water damage.
Cloud options 2026
Four serious options with different trade-offs:
- Apple iCloud Photos. 200 GB for €2.99/month, 2 TB for €9.99. Seamless iPhone integration. Stores in HEIC, which not every non-Apple recipient can open (see our HEIC post). Kept in the US and the EU (customer-selectable since 2024).
- Google Photos. 100 GB for €1.99, 2 TB for €9.99. Platform-agnostic, the best search (face recognition, location filter). Paid since 2021 — the famous "unlimited" free tier is history.
- Microsoft OneDrive. 100 GB for €2, 1 TB for €7/month (incl. Microsoft 365). Good Office integration, modest photo-specific features.
- Backblaze B2 / Wasabi. ~$6 per TB per month. Pure object storage; you build your own backup routine via rclone or Arq. No gallery, no sharing — but maximum value per byte.
Self-hosted: Synology Photos and Immich
For privacy-conscious users, self-hosting is mature in 2026:
- Synology Photos. A paid Synology NAS box (~€400 for an entry model, plus drives). Your own photo cloud in the house, automatic upload from smartphone apps, face recognition runs locally. A very mature ecosystem.
- Immich (open source). Self-hosted on a Raspberry Pi 5 (~€100) or a cloud VM. Functionally comparable to Google Photos: face recognition, location search, album management, mobile apps. Completely free, but you manage the infrastructure yourself.
- PhotoStructure. Closed-source, a one-time license, very robust with metadata maintenance.
Which master format?
For long-term archiving of photos there are four routes:
- Keep the original RAW. Maximum flexibility, largest file sizes. Per RAW typically 25–80 MB. 1 TB is enough for about 15–30k photos.
- DNG conversion. Convert manufacturer RAWs to Adobe's DNG — lossless, openly specified, vendor-independent, often 20–30% smaller files than the original RAW. Lightroom can automate this on import.
- JPEG XL from JPG. Converting existing JPG collections losslessly to JPEG XL saves ~20% storage without changing pixels.
- Leave JPG/HEIC/WebP as is. If the photo workflow was JPG-based from the start, later conversion to RAW is impossible. Leave JPG, optionally maintain XMP edits non-destructively.
Bit rot — the invisible enemy
Hard drives lose individual bits over the years without anyone noticing. An unreadable JPG after 10 years isn't rare. Three protection mechanisms:
- ZFS or Btrfs as the file system. Both have automatic checksum verification and self-healing. Synology and TrueNAS boxes use this by default.
- SnapRAID on Linux servers. Open source, parity-based bit-rot protection for RAID-like setups without a dedicated hardware controller.
- Verification routines. Hash-check once a quarter (e.g. with
shasum -a 256), restore deviations from the backup.
Smartphone-specific: AirDrop, auto-sync
iPhone users have it easy: iCloud Photos syncs automatically. Android users have several routes:
- Google Photos auto-sync. The default, but storage costs money.
- Synology Photos Mobile. If you have a NAS, the app uploads all new photos automatically.
- Resilio Sync or Syncthing. Open source, syncs directly between devices without a cloud intermediary.
Cost comparison for a 500 GB photo collection
- iCloud 2 TB: €9.99/month = €120/year.
- Google One 2 TB: €9.99/month = €120/year.
- Backblaze B2 500 GB: ~$3/month = €36/year.
- Synology DS224+ + 2× 4 TB: €600 one-time, then €0/year (electricity: ~€15).
After three years the NAS solution amortizes compared to cloud subscriptions. If you think about privacy and long-term costs, a NAS is structurally the best choice — but it needs someone to maintain it.
Concrete recommendation 2026
For most users a hybrid strategy is pragmatic:
- Working set: iPhone/Mac with iCloud Photos (200 GB for €2.99).
- Local backup: an external 4 TB SSD on a Mac Mini backup disk with Time Machine, or a Synology NAS for family multi-device setups.
- Offsite: Backblaze B2 for the NAS, or a second external SSD at a relative's.
What you should do now
- Today: back up all phone photos to an external disk.
- This week: check your cloud storage — is the plan enough?
- This month: do a test restore — can you really recover photos?
- This year: set up a NAS or cold-storage setup for long-term archives.
