Proxmox Backup Solutions: Local and Remote Options

Proxmox VE has become one of the most popular open-source virtualization platforms thanks to its powerful feature set, native clustering support, and flexible backup tools. As virtualization infrastructures grow, so does the importance of reliable, secure, and efficient backup systems. Whether you operate a home lab, a small business environment, or a full production cluster, understanding the various Proxmox backup solutions—both local and remote—is essential to ensuring uptime, reducing risk, and protecting critical workloads.

This comprehensive guide explores the full range of Proxmox backup options, including local storage, remote servers, cloud services, and hybrid solutions. You will also learn how to choose the best backup architecture for your environment, optimize performance, and ensure long-term data integrity.

Why Proxmox Backups Matter

Backups in Proxmox VE safeguard virtual machines (VMs), containers (CTs), and configuration data. Whether caused by hardware failure, accidental deletion, ransomware, or a botched update, system failures can result in costly downtime—and backups remain the best line of defense. Proxmox offers snapshot-based backups, incremental backups, compression, verification, and native integration with Proxmox Backup Server (PBS). With the right setup, VM backups can be automated, secure, and extremely efficient.

Proxmox Backup Types

Proxmox VE supports multiple backup methods that integrate with different storage types. Understanding these backup types helps ensure you choose the method that aligns best with your hardware resources and recovery objectives.

Snapshot Backups

Snapshot backups are fast and flexible, allowing VMs and containers to continue running during the backup process. They support incremental backups when used with Proxmox Backup Server and are ideal for environments requiring minimal downtime.

Suspend Backups

This method pauses the VM during the backup, ensuring data consistency at the cost of brief downtime. Suspend backups are useful for VMs running applications that do not support live snapshotting.

Stop Backups

The VM is powered off before the backup begins. These backups offer the highest level of consistency but cause the longest downtime, making them suitable only for non-critical systems.

Local Proxmox Backup Solutions

Local storage remains a popular option for homelab users and small environments due to its simplicity and low cost. Proxmox VE supports multiple local storage backends that work with the built-in backup system.

Directory Storage

Directory storage is the simplest local option. You can use any mounted storage device—HDD, SSD, or NVMe—as backup storage. Directory storage supports VZDump backups and is easy to maintain and expand.

ZFS Storage

ZFS offers built-in compression, checksums, snapshots, and redundancy. A ZFS pool can serve as a high-performance backup target, especially when utilizing SSDs or hybrid storage setups. ZFS checksumming helps ensure long-term data integrity.

LVM or LVM-Thin

While not as flexible for backups as directory or ZFS storage, LVM and LVM-Thin volumes can also act as backup targets. LVM-Thin offers snapshot capabilities, but lacks some of the advanced features of ZFS-backed storage.

Local NAS or Direct-Attached Storage

Some users opt for a small NAS connected over high-speed ethernet or USB. These solutions offer additional capacity without relying on internal server storage. Consider solutions like:

• USB 3.2 direct-attached storage
• 10GbE NAS units
• Locally mounted NFS shares

Remote Proxmox Backup Solutions

Remote backups add a critical layer of protection by ensuring your data is safe even if local hardware fails. Proxmox supports several remote backup methods, ranging from Proxmox Backup Server to cloud-based platforms and custom remote storage configurations.

Proxmox Backup Server (PBS)

PBS is the recommended solution for remote backups. Designed by the Proxmox team, it offers:

• Incremental backups
• Deduplication
• Compression and encryption
• Fast verification
• A web-based interface

PBS can be deployed on physical hardware or a VM and is optimized for high-performance remote backup operations. PBS also supports off-site synchronization, allowing you to replicate backups to a secondary backup server.

Remote NAS Devices (NFS, SMB)

Network-attached storage systems make effective remote backup targets when connected over a secure network. NFS is generally preferred for stability and performance. Remote NAS backups are easy to manage but may lack advanced features like deduplication unless paired with PBS.

Cloud Storage Platforms

Proxmox does not natively integrate with major cloud storage providers for backups, but you can still use cloud storage through mounted drive mechanisms or third-party tools. Popular cloud services include:

• {{AFFILIATE_LINK}} AWS S3
• {{AFFILIATE_LINK}} Backblaze B2
• {{AFFILIATE_LINK}} Wasabi Hot Cloud Storage
• {{AFFILIATE_LINK}} Google Cloud Storage

To use these services, you typically mount cloud storage locally or sync backups using tools such as Rclone.

SSH-Based Remote Backups

Proxmox supports remote storage mounted via SSHFS. This method is simple and offers secure transfer, but may be slower due to SSH overhead. It is suitable for small environments or off-site backups that do not require fast incremental restore speeds.

Hybrid Backup Architectures

Many users combine local and remote solutions for maximum durability. A hybrid approach typically includes:

• Local backup to ZFS or directory storage for fast restores
• Remote backup to PBS or cloud storage for disaster recovery

Local vs Remote Backup Comparison

Backup Type	Pros	Cons
Local Storage	Fast restores; low cost; simple setup	Vulnerable to local hardware failures
Remote PBS	Deduplication; incremental backups; encryption	Requires separate hardware/server
Cloud Backup	Off-site resilience; scalable	Slower; may require third-party tools
SSH/NAS Backup	Easy remote setup; cost-effective	Speed depends on network; fewer features than PBS

How to Choose the Best Proxmox Backup Solution

Choosing the right backup approach depends on your environment’s size, hardware resources, budget, and desired recovery times. Below are key factors to consider.

Environment Size

Small home labs can often rely on local storage or a single PBS instance, while medium to large deployments benefit from multi-tier backup systems.

Restore Time Requirements

If you require extremely fast restores, local storage—particularly SSD-backed ZFS—is ideal. For disaster recovery, remote PBS or cloud backups are essential.

Budget

Local storage is the least expensive, while cloud platforms may incur ongoing fees. PBS offers a strong balance of cost, performance, and features.

Security Needs

PBS supports client-side encryption, making it ideal for untrusted storage environments or remote datacenters.

Best Practices for Proxmox Backups

Implementing proper backup practices helps maintain system integrity and ensures your data remains recoverable.

• Use PBS whenever possible for incremental backups
• Schedule nightly or weekly automated backups
• Verify backups regularly
• Store at least one backup off-site
• Use encryption for remote backups
• Document your restore procedures

Example Backup Deployment Scenarios

Home Lab Setup

A typical home lab can utilize local ZFS storage for fast backups and a small remote PBS instance hosted on low-power hardware. Affordable storage options such as {{AFFILIATE_LINK}} WD Red NAS drives make this easy to manage.

Small Business Deployment

Small businesses can benefit from dual PBS servers—one local and one remote. Local PBS handles nightly backups while the remote server syncs for disaster recovery. Off-site storage using Backblaze or Wasabi can further protect against data loss.

Enterprise Virtualization Cluster

Larger environments typically combine on-prem and cloud backups, multiple PBS nodes, and automated sync schedules. These setups prioritize scalability, redundancy, and compliance requirements.
