Managing Workers

To perform most data protection and disaster recovery operations, Veeam Plug-in for Scale Computing HyperCore 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.

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 Plug-in for Scale Computing HyperCore tries to launch the worker and test its configuration. If no worker VM has been previously deployed, Veeam Plug-in for Scale Computing HyperCore deploys the VM using the worker configuration saved to the configuration database. Then, Veeam Plug-in for Scale Computing HyperCore powers on the worker VM and installs system updates (if available). When the backup or restore session completes, Veeam Plug-in for Scale Computing HyperCore 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.
