How to Back Up Your NAS to Multiple Clouds — 3-2-1 Backup Strategy with RcloneView
One cloud backup is good. Two cloud backups is better. The 3-2-1 rule says: 3 copies, 2 different media, 1 off-site. Your NAS is copy one. Cloud A is copy two. Cloud B is copy three. RcloneView automates all of it.
A NAS is a fantastic centralized storage solution, but it's still a single device in a single location. Hardware failure, fire, theft, or natural disasters can destroy it along with everything on it. Backing up to multiple cloud providers — on different infrastructure, in different regions — gives you true disaster recovery.

The 3-2-1 Strategy
| Copy | Location | Provider |
|---|---|---|
| 1 (primary) | NAS (local) | Synology/QNAP |
| 2 (cloud backup) | Cloud A | Backblaze B2 ($6/TB) |
| 3 (cloud backup) | Cloud B | AWS S3 or Wasabi |
Three copies. Two different types of storage (local NAS + cloud). One off-site (cloud is off-site by definition).
Setup with RcloneView
1) Connect your NAS and clouds
2) Create backup jobs for each cloud
Job 1: NAS → Backblaze B2 (primary cloud backup). Job 2: NAS → AWS S3 (secondary cloud backup).
3) Schedule nightly backups
Stagger the schedules:
- 2:00 AM → NAS → Backblaze B2.
- 4:00 AM → NAS → AWS S3.
4) Use Batch Jobs for automation
v1.3 Batch Jobs chain everything:
- Copy NAS → B2.
- Copy NAS → S3.
- Compare NAS vs B2.
- Compare NAS vs S3.
- Notify via Slack.
5) Verify both backups
Cost Optimization
| Data Volume | B2 Monthly | S3 Standard-IA Monthly | Total |
|---|---|---|---|
| 1 TB | $6 | $12.50 | $18.50 |
| 5 TB | $30 | $62.50 | $92.50 |
| 10 TB | $60 | $125 | $185 |
For the secondary backup, use cheaper tiers: S3 Glacier ($4/TB) or Wasabi ($7/TB with free egress).
