With more businesses adopting Proxmox VE, Proxmox Backup Server (PBS) has quickly become a popular backup choice due to its native integration. However, as IT environments become more complex and cyber threats continue to evolve, organizations need to ask: Is PBS still sufficient to meet enterprise-grade data protection needs?
PBS: Native simplicity for Proxmox VE
Proxmox Backup Server (PBS) is the native backup solution for Proxmox VE. As an open-source solution, it is free to use, with optional enterprise subscriptions available for technical support. It provides essential backup capabilities, including incremental backups, deduplication capabilities, and multiple recovery options. It also integrates seamlessly with the Proxmox interface, allowing administrators to manage backup jobs directly from the same console.
PBS is an good starting point. However, as business requirements evolve, it’s important to evaluate whether its capabilities align with your environment.
- Organizations with hybrid environments: PBS is designed specifically for Proxmox VE. If your infrastructure also includes other hypervisors, or even physical and cloud workloads, managing backups across multiple tools can increase operational complexity.
- Organizations running business-critical applications: PBS does not provide application-aware backup for coordinating with applications such as databases before a backup is taken. Without it, recovery may include inconsistent transactions.
- Organizations with cyber resilience requirements: PBS does not natively provide WORM or air-gapped protection. Organizations typically rely on manual backup version locking or infrastructure such as tape to implement immutable or air-gapped backup strategies.
- Organizations requiring rapid and reliable recovery: PBS can validate backup integrity, but it cannot verify whether workloads can actually start successfully. Recovery is also limited to Proxmox VE, with no support for cross-platform and parallel recovery, which may slow recovery during large-scale disasters.
Overall, PBS is well suited for organizations with simple Proxmox environments. As backup requirements evolve, however, its native capabilities may no longer be sufficient. At that stage, organizations should consider a more comprehensive enterprise backup platform.
ActiveProtect: Advanced data protection for Proxmox VE
ActiveProtect, Synology’s all-in-one backup solution, protects Proxmox VE alongside physical servers, other virtualization platforms, public cloud VMs, and SaaS applications from a single platform. For Proxmox VE virtual machines, ActiveProtect provides one of the industry’s most comprehensive backup implementations.

Compared with PBS, ActiveProtect builds upon its core strengths with broader workload coverage, enterprise-grade cyber resilience, and recovery assurance.
Efficient and reliable backup
For Proxmox VE, ActiveProtect uses an agentless, hypervisor-level backup architecture. Like PBS, it leverages QEMU dirty bitmap to track changed blocks, so only modified data is transferred after the initial backup. Beyond this, ActiveProtect’s exclusive SURE Technology, which performs global deduplication across workloads, further minimizing backup traffic and storage consumption while maintaining high backup performance. According to internal testing, ActiveProtect wrote about 91% less data than PBS in the same full-dedupe scenario and delivered nearly 2× higher throughput during concurrent Proxmox backup operations, since PBS itself does not support concurrent backup jobs.
In addition, ActiveProtect supports application-aware backups. For organizations running business-critical applications, this helps to ensure consistent recovery.
Centralized and automated protection
ActiveProtect provides centralized management, allowing organizations to manage diverse workloads from a single interface — including off-site backups.
ActiveProtect also simplifies day-to-day administration through Auto Protection. Backup policies can be assigned at the cluster, node, resource pool, or tag level. As new virtual machines are created, they are automatically discovered and protected based on their assigned policy, eliminating manual effort and the risk of missed backups.
Built-in cyber resilience
While facing modern ransomware attacks, immutable and isolated recovery environments are essential to data protection. However, immutable and air-gapped protection typically rely on manual configuration or additional infrastructure for PBS. ActiveProtect integrates cyber resilience directly into the backup platform.
ActiveProtect provides native WORM protection. Once written, the backup data can be automatically locked for a defined retention period, preventing it from being modified or deleted throughout its lifecycle.
To further reduce the attack surface, ActiveProtect’s smart Air Gap permits data transfers only from authorized source servers during predefined transmission windows. If the transfer completes ahead of schedule, the system automatically disconnects, minimizing exposure time without manual intervention.
Always recovery ready
Recoverability and rapid restoration are central to data protection. To ensure recoverability, ActiveProtect supports backup verification, which can automatically restore workloads in a built-in isolated environment, boot the operating system, and record the verification process, allowing organizations to validate actual recoverability without performing manual tests.
Beyond recovery assurance, ActiveProtect also accelerates recovery by allowing multiple virtual machines to be restored simultaneously with one click. ActiveProtect also supports cross-platform restoration, allowing workloads to be recovered across supported on-premises hypervisors or into public clouds such as Microsoft Azure and Amazon EC2. These capabilities help minimize downtime and restore business quickly during a disaster.
Conclusion
Choosing the right backup solution starts with understanding your environment and protection requirements. If Proxmox is your primary platform and your backup needs are straightforward, PBS may be all you need. As your environment grows and recovery requirements become more demanding, ActiveProtect provides the additional capabilities needed to protect a modern enterprise.
