Hi, I have a Sun Fire V210 server with fcal disks and I can not get more than 6MB/s from the root filesystem.
On a filesystem with larger files I have seen transferrates of about 15MB/s when using netbackup and multiple filesystems backupped at the same time. Netbackup does not get any higher transferrate for the root filesystem than bacula so I think the bacula filedaemon is quite good. I have gigabit ethernet and a LTO-3 drive on the bacula system and gigabit ethernet and multiple SDLT dives on the netbackup system so I do not think the problem is on the backup server side. If I backup filesystems located on diferent disks with the netbackup solution at the same time I get a much higher total transferrate. /Ove On Fri, 2005-11-25 at 20:45, Phil Stracchino wrote: > Ove Risberg wrote: > > What: I want to start multiple backup jobs on one client to get the > > fastest possible backup of my server but I do not want a > > complicated configuration or restore process. > > > Why: Multiple concurrent backups of a large fileserver with many > > disks and controllers will be much faster. > > I question this assumption.
