Windows Server Backup and multi-core systems

Some backup software companies list "multi-core processor optimization" or "take advantage of multi-core CPUs"...

but is the native Windows Server Backup in Windows Server 2008 or SBS 2011 capable of running on multiple cores simultaneously? (the older ntbackup.exe was not)

    No, but WSB does not have any features that would benefit from it anyways. Backups generally aren't CPU intensive. The bottlenecks are in transfer and write performance. And multiple cores won't help that.

    Now programs that do multi-system deduplocaton, heavy compression, or such other features can benefit from multiple cores. But WSB doesn't have those features.

    Dint get me wrong, it'll run duping on a multi-core processor. It just hasn't been written to multi-thread workloads, but as I explained above, there aren't multiple workloads to spread about so it is something of a non-issue.
