Managing Workers
To perform most data protection and disaster recovery operations, Veeam Backup for Proxmox VE uses workers. Workers are Linux-based VMs that process backup workload and distribute backup traffic when transferring data to backup repositories. Each worker is launched on a specific host for the duration of a backup or restore operation. As soon as a backup or restore session starts, Veeam Backup for Proxmox VE launches a worker, tests its configuration and installs system updates (if available). When the backup or restore session completes, Veeam Backup for Proxmox VE shuts down the worker VM so that it can be used for other sessions later.
Important |
To modify the worker settings, use the Veeam Backup & Replication console as described in section Editing Workers. Making any configuration changes to VMs running as workers manually in the Proxmox VE administration portal may cause technical issues. |
Worker Lifecycle
When you add a worker to the backup infrastructure, its configuration is saved to the Veeam Backup & Replication configuration database, but no VM is actually deployed on the host unless you choose to test the configuration. In the latter case, a VM (worker VM) is deployed and shut down after the test operation completes.
As soon as a backup or restore session starts, Veeam Backup for Proxmox VE tries to launch the worker and test its configuration. If no worker VM has been previously deployed, Veeam Backup for Proxmox VE deploys the VM using the worker configuration saved to the configuration database. Then, Veeam Backup for Proxmox VE powers on the worker VM and installs system updates (if available). When the backup or restore session completes, Veeam Backup for Proxmox VE shuts down the worker VM so that it can be used for other sessions later.
During the lifecycle, a worker can obtain one of the following statuses:
- Configured — the worker configuration is added to the Veeam Backup & Replication configuration database.
- Testing — the worker configuration is being updated and tested.
- Working — the worker is processing a backup or restore operation.
- Shut Down — the worker is powered off.
