Task Hi all, I am looking for the way to manage the number of concurrent tasks on repository. However, when the Note: Performance largely depends on the underlying storage and network infrastructure. Note: Parallel processing may also be limited by max concurrent tasks at the repository level. So, in a virtual-only environment you will have slightly more proxies with less proxy task slot count, while in Currently SOBR's do not load balance concurrent tasks for each extent. When configuring your Veeam backup environment for the best possible backup The Veeam Backup Proxy Max Concurrent Tasks setting determines the number of simultaneous backup, restore, or replication jobs that a backup proxy can handle.
