You should be able to hit 300-400Mb/s assuming you are spooling to a mechanical hard drive or cheap SSD. Faster than that requires an array of disks setup for striping. > Did someone tried to tweak some network parameters (On linux Debian) ? > I think about Jumbo frames, but because it is a vlan-wide parameter and > bacula > is not the same on this network, it is a little complicated to deploy. I have some settings but they won't gain much until other areas are addressed. Before you attempt to do anything, you will need to benchmarking network speeds and speeds of simple file transfers, etc. You need to get a handle on how fast your network and disk susbsystems are before you can see how fast Bacula can run. In my experience throughputs are far more limited by client disk speed/loading (busy clients can be very slow to provide data), server disk speeds/loading and finally by network limitations - in that order. Tuning networking when the bottlenecks are elsewhere will give few noticeable improvements until those other areas are quantified and addressed if needed. I can easily sustain 1Gb/s on terabyte-scale backups without jumbo packets, but it took a bit of tuning of the client's disk handling to achieve it and I have hardware arrays with 96 drives onboard apiece. The tuning was mainly intended to improve its performance as a fileserver and came at the expense of its usefulness as an interactive machine (it's a dedicated fileserver) - there's no such thing as a free lunch. ------------------------------------------------------------------------------ Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.
