Before You Begin

Before you add a worker to the backup infrastructure, consider the following:

• It is recommended that workers are deployed in each cluster. If no worker is deployed in the cluster, performance of backup operations will be affected as Veeam Backup & Replication will use a worker deployed in another cluster.
• It is recommended that the number of configured workers does not exceed the number of hosts in the cluster.

• Each worker must be provided with sufficient compute resources to handle backup and restore tasks in parallel. The maximum number of concurrent tasks is configured in worker settings — if this number is exceeded, the worker will not start a new task until one of the current tasks finishes.
• You can change the maximum number of concurrent tasks (the best practice is to allocate 1 vCPU and 1 GB RAM for each additional task) while deploying a new worker or editing settings of an existing one.

• It is recommended the total number of concurrent tasks configured for all workers deployed in the cluster does not exceed the number of physical disks added to the cluster.
