Considerations and Limitations

When you plan to deploy and configure Veeam Backup for Proxmox VE, keep in mind the following limitations and considerations.

Configuration

When configuring Veeam Backup for Proxmox VE, consider the following:

• Veeam Backup for Proxmox VE supports Proxmox Virtual Environment version installed using the official ISO image provided by Proxmox only.

• Each node of a Proxmox VE cluster must be added to the backup infrastructure separately.
• The name of the cluster must not be changed in the Proxmox VE administration portal after you add it to the backup infrastructure.

Storage

When configuring Proxmox VE storage, consider the following:

• Veeam Backup for Proxmox VE supports backup and restore of VMs that store their disks in any Proxmox VE storage except for the BTRFS and custom storage.
• The number of concurrent backup operations performed on each storage is limited to 4 to avoid excessive load on the production environment. To change the limit, contact Veeam Customer Support.

Workers

When configuring workers, consider the following:

• Veeam Backup for Proxmox VE uses only standard bridge networking for worker VMs — Open vSwitch is not supported.
• The default local storage is enabled on hosts where workers are deployed. If you cannot use the default storage in your environment, contact Veeam Customer Support.

Backup

When protecting Proxmox VE resources, consider the following:

• Veeam Backup for Proxmox VE does not support backup of Proxmox VE containers (LXC containers).

• Veeam Backup for Proxmox VE does not support backup of VMs created as linked clones of a template. Backup of full clones is supported.

• Veeam Backup for Proxmox VE does not support backup of iSCSI disks. If iSCSI disks are attached to a VM included into a backup job, these disks will be skipped from processing.
• Veeam Backup for Proxmox VE does not support backup of VM permissions granted to users, user groups and API tokens.
