Matt> I have two identical Win 2k3 servers (Dell PowerEdge 2800, Matt> U320 >> RAID5, Matt> dual P4 Xeon 2.8) that I need to backup data onto an FC3 Matt> server >> running Matt> Bacula (P4 2.8GHz, USB2 HDD). All three machines have Gigabit >> cards Matt> running on a Gigabit switch with appropriate Cat5e cables. >> Matt> Server1 has two files totaling 5Gb. Bacula grabs these files Matt> at >> about Matt> 25MB/sec - total backup time is under 4mins. Matt> Server2 has ~4000 files totaling 100Gb. The problem is that >> Bacula is Matt> only running at about 50Kb/sec for this server - simple maths >> tells us Matt> that it's going to take 3.5 weeks to backup the entire server! >> Matt> There's obviously something awry here - can anyone give me any >> ideas Matt> what to look into?

Matt> The bacula-fd process on Server2 is using at most about 2%. Mem usage Matt> is very low (3Mb). Nothing else is using the processor or disks Matt> intensively on that machine at the moment and bconsole is reporting Matt> about 3MB/sec transfer (speed changes wildly it seems, but never very Matt> fast!) Matt> The bacula server is running around 5-15% for bacula-sd. Again, nothing Matt> much else is happening on that server, load average: 0.21, 0.12, 0.09. Matt> Is there any profiling I can run on the Windows FD client, or at least Matt> see a file-by-file progress? You can see which file it is doing by using the 'status client' command in bconsole. You could also try changing the Messages resource in bacula-dir.conf to send "saved" messages to the console (by default it says 'console = all, !saved' which discards them). I've not tried this, so I don't know if it produces messages as the saving happens or only at the end. Finally, running bacula-fd in debugging mode (using the -d option from a Command window instead of as a service) will output lots of info (not sure where it goes on Windows). __Martin ------------------------------------------------------- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?
