I've just been experimenting with this to replace tape altogether - USB 3 controller then copy the veeam files to the USB disk at the end of the week. We don't backup directly to USB because it's just a single slow drive so backups, especially the synthentic full, would take forever, whereas sequential streaming should be OK.
Anyway, for those using Windows Server 2008 (not R2) - you need the Windows Dynamic Cache Service
installed, otherwise copying to USB the Windows cache fills the entire system memory which is completely pointless and pretty much everything else will be paged, effectively stalling the server until the job eventually completes (and it will be, eventually). The server will be totally unresponsive, won't be able to RDP or even use console in my experience.
After some experimentation (8GB RAM in the host), having min of 1GB and max of 2GB seems to be working well and ensures there is plenty of RAM available for the SQL service and everything else.
