If you’re looking for a simple and effective way to mount OneDrive on Proxmox VE, this step-by-step tutorial will guide you through the entire setup process.

By integrating Microsoft OneDrive with Proxmox VE, you can expand your storage capabilities and create a flexible cloud backup solution for your virtual machines. This approach is especially useful for:

• 💾 VM backups (VZDump)

• 📦 ISO image storage

• 🗂️ Snapshot archives

• 🔄 Offsite redundancy

Using Rclone, we will authenticate a OneDrive account and mount it directly as a storage directory inside Proxmox. The configuration works perfectly for both home lab environments and production servers.

Cloud integration improves:

• ✅ Data redundancy

• ✅ Offsite backup strategy

• ✅ Accessibility

• ✅ Infrastructure scalability

Let’s start and configure OneDrive as cloud storage in Proxmox VE within minutes.

🧰 Step 1: Install Rclone & FUSE on Proxmox

SSH into your Proxmox node as root and run:

Enable allow_other in FUSE (if not already configured):

This ensures proper mount permissions when using FUSE-based filesystems.

💻 Step 2: Create OneDrive Remote on Windows Using Rclone Config

On Windows, download Rclone.
In this guide, version v1.71.0 is used (you may use the latest version):

https://downloads.rclone.org/v1.71.0/

Extract the package and open Command Prompt as Administrator, then run:

Configuration inputs:

• client_id> and client_secret> → Press Enter (leave blank unless using a custom client)

• Choose Microsoft Cloud Global (for Microsoft 365 / OneDrive Personal & Business accounts)

• tenant: → Press Enter

• Authenticate via Microsoft login when redirected

After authentication completes, your OneDrive remote configuration will be created successfully.

📂 Step 3: Copy the Rclone Config File to Proxmox

On Proxmox, create the configuration directory:

On Windows, locate the config file path:

Copy the generated rclone.conf file to:

Set proper permissions:

This ensures secure access to authentication credentials.

📌 Step 4: Create Mount Folder and Mount OneDrive

Create the mount point:

Test mount (foreground mode):

Explanation:

• onedrive-pve: → Remote name

• Backup → Folder name on OneDrive

• --vfs-cache-mode full → Required for stable read/write operations

• --daemon → Runs mount in background

At this point, your OneDrive storage is mounted successfully.

🔁 Step 5: Create Systemd Service for Auto Mount on Reboot

#1 Create Service File

Paste:

Explanation:

• [Unit] → Start after network is online

• ExecStart → Mount command

• Restart=always → Auto-restart if crash

• multi-user.target → Run at normal Proxmox boot

#2 Enable and Start Service

#3 Verify Mount Status

💡 Tips

• --vfs-cache-mode full is required for stable OneDrive mount.

• For multiple remotes, create separate service files.

• To unmount temporarily:

🖥 Step 6: Add OneDrive Storage to Proxmox GUI

Navigate to:

Datacenter → Storage → Add → Directory

Fill in:

• ID: onedrive

• Directory: /mnt/onedrive

• Content: Select VZDump backup file (recommended for backup only).
  You may also select ISO image / Container template if needed (performance considerations apply).

• Node: Select your Proxmox node

Click Save.

Now when creating a backup job:

Datacenter → Backup

You can select Storage: onedrive.

Proceed to back up one VM to verify cloud integration.

🎯 Conclusion

Mounting OneDrive as cloud storage on Proxmox VE using Rclone is a powerful and flexible solution for implementing offsite backup and cloud-based storage integration.

This configuration provides:

• ☁️ Cloud redundancy

• 🔐 Secure authentication

• 🔄 Automated mount at boot

• 💾 Reliable VM backup destination

Whether you are running a homelab or managing production infrastructure, integrating Microsoft OneDrive into Proxmox enhances scalability and backup resilience.
