Managing Workers
To perform most data protection and disaster recovery operations, Veeam Backup & Replication 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 & Replication launches a worker, tests its configuration and installs system updates (if available). When the backup or restore session completes, Veeam Backup & Replication 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 & Replication tries to launch the worker and test its configuration. If no worker VM has been previously deployed, Veeam Backup & Replication deploys the VM using the worker configuration saved to the configuration database. Then, Veeam Plug-in for Proxmox VE powers on the worker VM and installs system updates (if available). When the backup or restore session completes, Veeam Backup & Replication 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.
