Migration to Proxmox VE from VMware: A Deep Dive into Backup Strategies and Cloud Integration

Da LI 03/19/2024 0 Comments

Selecting the right virtualization platform is a critical decision for IT departments aiming to boost efficiency, reduce costs, and scale operations effectively. With VMware and Proxmox VE leading the pack, each platform offers distinct advantages. Proxmox VE, with its open-source framework, is particularly appealing for its cost-effectiveness and flexibility. This contrasts VMware, a proprietary solution known for its comprehensive support and scalability, though often at a higher cost. Recent changes in VMware’s licensing, influenced by corporate decisions, have led some organizations to consider Proxmox VE as a more customizable and financially accessible option.

The Critical Role of Backup in Migration

Migrating from VMware to Proxmox VE necessitates a strategic approach, with data backup being a cornerstone of the transition. It’s crucial to maintain backups both before and after the migration for both virtualization platforms. Additionally, it’s necessary to retain backup data for a period, as VM administrators need to run test systems to ensure everything operates smoothly. This process highlights the differences in backup methodologies between VMware and Proxmox VE, each tailored to its respective platform’s architecture.

VMware Backup vs. Proxmox VE Backup

For VMware environments, usually the backup software adopts an agentless approach, streamlining the backup process by eliminating the need for installing backup agents on each VM. This method leverages VMware vCenter and a virtualization proxy server to manage VMware snapshot processing and communication with the storage destination. It enables auto-discovery and protection of new or modified VMs, ensuring comprehensive coverage. Additionally, the backup software offers instant recovery options, including the ability to quickly map Virtual Machine Disk (VMDK) images back to the same or alternate VMs, significantly reducing downtime and enhancing data accessibility. The support for both physical and virtual environments underlines the backup solution’s versatility, catering to a wide range of backup and recovery needs.

In contrast, the approach for Proxmox backup with backup software is similarly agentless but specifically tailored to the Proxmox VE platform. It incorporates hypervisor snapshot management, enabling efficient backup and recovery processes. One of the features for Proxmox VE backups is the use of Changed Block Tracking (CBT), which allows for incremental backups after an initial full backup, focusing only on changed data blocks to minimize backup windows and storage requirements. Backup software also provides a disk-exclusion option, enabling users to exclude certain VM disks from backups. This can be particularly advantageous for optimizing backup storage by omitting disks that contain temporary or non-essential data.


The distinction between VMware and Proxmox backup strategies illustrates the tailored functionalities that backup software must provide to effectively cater to each platform. VMware’s solution emphasizes comprehensive coverage, instant recovery, and seamless integration within a diverse and complex IT infrastructure. Meanwhile, Proxmox’s backup solution focuses on efficiency, flexibility, and the specific virtualization technologies of Proxmox VE, offering scalable and efficient data protection. This highlights the critical role of choosing a backup solution that not only matches the technical framework of the virtualization environment but also supports the strategic goals of the organization’s data protection policies.

Choosing the Right Backup Destination of Cloud

When it comes to selecting a backup destination, options abound, including disk, tape, and cloud storage. Based on our recent experience, many user choose to backup VMs onto cloud, Wasabi Cloud Storage stands out for its affordability, reliability, and performance, making it an excellent choice for Proxmox VE backups. Its seamless integration with DPX vPlus backup solutions offers scalability and off-site data protection, without the burden of egress fees or hidden costs.

Securing Proxmox VE Backups with Wasabi Cloud Storage

The process of backing up Proxmox VE to Wasabi Cloud Storage is straightforward, beginning with setting up a Wasabi storage bucket and configuring DPX vPlus to use Wasabi as a backup destination. This approach not only ensures cost-effective cloud storage but also leverages DPX vPlus’s reliable backup capabilities, providing a robust data protection strategy for your virtual infrastructure.


The transition from VMware to Proxmox VE, motivated by the desire for a more flexible and cost-effective virtualization solution, highlights the importance of a well-planned backup strategy. The comparison between VMware and Proxmox VE backup methodologies reveals the need for backup solutions that align with the specific requirements of each platform. Integrating Proxmox VE backups with Wasabi Cloud Storage through DPX vPlus offers a compelling solution, combining cost-efficiency with reliable data protection. For organizations contemplating this migration, understanding these differences and options is crucial for ensuring data integrity and system continuity.
