Hi Uwe, We are using MySQL. It hasn't been optimized for bacula usage. I installed both bacula and mysql via apt-get. We aren't using spooling. These are just local backups. The director / sd machine was bought in 2009 and has 2 Intel Xeon E5410, 2.33 GHz CPUs and 16 GB memory. Disks are SATA. I'm out of town today and tomorrow and will try to find other specs tonight or this weekend.
I ran another test: I backed up the imaging data tarfiles to the same disk pool as I used for the operating system test backup. The rate was 23 MB/s, same as backup of the imaging data tarfiles to tape. Thanks!

What DB backend are you using? Is the db optimized for bacula usage? How fast are your disks? Are you using attribute / job spooling? What's the hardware spec of the director / sd machine? What's your connection / max throughput to the clients? All the best, Uwe -- IMPORTANT NOTICE: This e-mail is meant only for the use of the intended recipient.
