Synology → Cloud, Made Easy: Off-Site Backups & Sync with RcloneView

Tech Writer

Keep a second copy off-site without scripts or terminals. Back up your Synology NAS to Backblaze, Google Drive, Amazon S3, pCloud, Wasabi, and more—visually, reliably, and on a schedule.

Introduction — Why push your Synology backups off-site?

A NAS is fantastic for fast, local access—family photos, creative projects, and team shares are only a LAN away. But on-prem only has risks: theft, fire, accidental deletion, or multi-drive failures. Adding an off-site cloud copy gives you:

Resilience: survive local disasters with a remote, recoverable copy.
Flexibility: restore anywhere, even when you’re away from the office/home.
Governance: combine NAS retention with cloud bucket versioning and policies.

Synology NAS at a glance

Central storage reachable via SMB/NFS (mount as a local folder) or network endpoints like WebDAV and SFTP.
Ideal for always-on backups, media hosting, and team file hubs.

Cloud destinations at a glance

Google Drive: collaboration and sharing in Google Workspace.
Amazon S3 / Wasabi / Backblaze B2: object storage with buckets, regions, and lifecycle rules.
pCloud: user-friendly storage with generous file handling.

Why send NAS → cloud now?

Create an off-site safety net.
Standardize backups to a single destination (or multi-cloud).
Leverage policies & versioning available on many cloud platforms.

Step 1 — Preparation

Before you begin:

Choose your scope — which shared folders on Synology (e.g., /photo, /projects, /backup) will go to the cloud?
Confirm cloud capacity — ensure the target account or bucket has room (plus headroom for versions).
Pick a NAS connection method
- Local path: mount the NAS share via SMB/NFS on your OS and use it as Local in RcloneView.
- WebDAV: enable Synology’s WebDAV Server and connect with WebDAV in RcloneView.
- SFTP: enable SSH/SFTP on Synology and connect with SFTP.
Pick your cloud — Google Drive, Amazon S3/Wasabi, Backblaze B2, pCloud, etc.
Decide cadence — one-off archive, periodic sync, or nightly scheduled jobs.
Pilot first — run a small test to validate paths, permissions, and throughput.

3) Step 2 — Wire up connections in RcloneView

RcloneView wraps rclone’s configuration into a guided, click-through flow.

Open RcloneView → click + New Remote
Add Synology (source) via one of:
- Local: pick your mounted NAS folder (e.g., Z:\NAS\Projects or /Volumes/NAS/Projects)
- WebDAV: use Synology’s WebDAV endpoint/credentials → name it (e.g., NAS-WebDAV)
- SFTP: host/IP, port, and account → name it (e.g., NAS-SFTP)
Add Cloud (destination), for example:
- Google Drive: OAuth login → name it MyGoogleDrive
- Amazon S3 / Wasabi: S3 provider → access key/secret, region, bucket → name it MyS3 / MyWasabi
- Backblaze B2: B2 provider (or S3-compatible endpoint if applicable) → name it MyB2
- pCloud: sign-in/token flow → name it MyPcloud
Confirm both appear side-by-side in the Explorer pane.

4) Step 3 — Run the backup/sync (three practical methods)

RcloneView offers three straightforward approaches. Start small, then scale with confidence.

A) Drag & Drop (manual copy)

Open Synology (Local/WebDAV/SFTP) on one side and your cloud on the other, then drag folders/files across.
Great for selective moves and quick wins.

B) Compare & Copy (preview changes)

Run Compare to see what’s new/changed on the NAS vs. your cloud bucket/drive.
Copy only deltas—fewer surprises, faster runs.

C) Sync & Scheduled Jobs (automate)

Use Sync to mirror selected NAS folders into your cloud destination.
Dry-run first, then save as a reusable Job and add a schedule (nightly/weekly).

Pro tips

For S3-type clouds (S3/Wasabi/B2 S3-compatible), pre-create buckets and pick the correct region.
Enable versioning on supported buckets for safer rollbacks.
Keep NAS sources read-only during cutover to prevent drift.
Use filters to exclude cache/temp folders from backups.

5) Conclusion — Key takeaways & extra tips

Why do this: a durable off-site safety net, faster disaster recovery options, and unified retention.
How it works: RcloneView connects your Synology NAS and cloud destinations, then lets you Drag & Drop, Compare, or Sync—with scheduling for hands-off backups.
Scale safely: pilot first, respect provider quotas, and monitor job logs for a clean audit trail.
