Most people think about backups right after losing files. The setup takes under an hour and costs next to nothing; the regret of not doing it can last much longer. This is the practical 2026 backup plan — automated, offsite, and actually tested.
What changed in 2026
- Cloud storage got cheaper and faster. Backblaze Personal Backup runs ~$9/month for unlimited data; Apple iCloud+ and Google One have grown their tiers. Offsite backup is no longer a premium.
- NAS drives with RAID got more affordable. Entry-level 2-bay NAS (Synology, QNAP) can be had for ~$150–$200 body-only, making a proper local backup layer accessible.
- Ransomware matured. Modern variants explicitly target backup folders and connected drives; keeping at least one backup air-gapped or immutable is now standard advice, not paranoia.
- Apple's Continuity and Windows Backup now integrate with their respective cloud services more tightly, so the default "do nothing" path at least syncs recent files — but that is still not a full backup.
The 3-2-1 rule
The industry-standard rule: 3 copies of your data, on 2 different media types, with 1 copy offsite.
| Copy |
Example |
Purpose |
| 1 — Primary |
Laptop / phone / desktop |
What you work from |
| 2 — Local backup |
External drive or NAS |
Fast restore, same room |
| 3 — Offsite cloud |
Backblaze, iCloud, Google One |
Survives theft, fire, flood |
One drive isn't enough. Two copies in the same house isn't enough. You need all three tiers.
How to set it up — step by step
Step 1: Pick a cloud backup service
- Mac: Time Machine to an external drive + iCloud Backup or Backblaze for offsite.
- Windows: File History to an external drive + Backblaze Personal Backup or OneDrive Backup for offsite.
- Phone: iCloud Backup (iPhone) or Google One Backup (Android) on automatic.
Enable the cloud backup first — it's the most important tier and runs in the background.
Step 2: Attach a local external drive
Use a 2 TB+ USB-C drive (~$50–$70). Set it to run automatically:
- Mac: Time Machine → Select Disk → turn on.
- Windows: Settings → System → Storage → Advanced storage settings → Backup options.
Step 3: Schedule and verify
- Verify your first backup completed in the software dashboard.
- Do a test restore: pull one folder back from both the local and cloud backups.
- Set a calendar reminder every 3 months to confirm backups are still running.
Step 4: Handle critical files separately
Documents you can't recreate (tax files, photos, legal docs) should also be in a second cloud service. iCloud + Backblaze is a strong combo because they use independent infrastructure.

How to pick
- iPhone user on Mac? Time Machine + iCloud + Backblaze is the gold standard trifecta.
- Windows-only? File History locally + Backblaze offsite covers both tiers cleanly.
- Android? Google One Backup for the phone; Backblaze for the PC.
- Photos-heavy? Add Google Photos (free up to 15 GB) or Amazon Photos (free unlimited with Prime) as a dedicated photo layer.
- High security / sensitive data? Look at Arq 7 with encryption-before-upload to a storage backend you control.
Common mistakes
Backup folder on the same drive. If the drive fails or your laptop is stolen, the backup goes with it. Offsite is mandatory.
Sync ≠ backup. Dropbox, Google Drive, and iCloud Drive sync changes — including deletes. If you delete a file and the 30-day recovery window lapses, it's gone. Sync services are not backup services.
Never testing restores. Test a restore at least twice a year. A backup that can't restore is just a false feeling of safety.
Skipping phone backup. Phones hold years of photos and messages. Enable iCloud or Google One backup over Wi-Fi.
Forgetting external drives fail too. Hard drives have a 3–5 year mean lifespan. Replace local drives before they're old, not after they fail.
What to skip
- RAID as a backup. RAID protects against a drive failure but not against accidental deletion, ransomware, or theft. It is not a backup.
- Full manual copy-paste. You'll do it twice, then stop. Automate every tier.
- Archiving to optical discs unless you need long-term archival (M-DISC has its place, but not for daily backups).
FAQ
How often should backups run?
Cloud backup should be continuous or nightly. Local Time Machine / File History runs hourly by default, which is fine.
Is iCloud enough as my only backup?
No. iCloud is one copy in one location. You need a local copy and ideally a second independent cloud service for truly critical data.
What's the best free option?
Google One Backup (Android + 15 GB free) or iCloud (iPhone + 5 GB free) for phones. For a PC, a single external drive with File History / Time Machine is a significant improvement over nothing — just add a free tier of cloud backup for offsite.
How do I back up an external hard drive?
Include it in your Backblaze backup (it supports external drives connected at time of backup). Or use a second drive in a rotation scheme.
