Hi all,
I have a bacula setup with a bacula-dir and bacula-sd on version 5.2.12 and a
bunch of Linux clients (also with 5.2.12). Everything works fine, I get speed
rates at about 70-80 MByte/s from these Linux clients. Two months ago I have
added a bunch of Windows Server 2008 R2 machine (both virtual and physical
ones) to the setup with bacula-fd in version 5.2.10 and the speed is only at 36
MByte/s. I use netio for measuring the speed between the servers and the
bacula-sd (is on the same host with the bacula-dir and the database) and get
around 90 MByte/s. The bacula-sd/fd/database is connected with 10 GBit/s and
all hosts (Windows and Linux) with 1 GBit/s to the some Layer 2 Network (no
router between them). The backup data on the Linux and Windows server are very
similar (a lot of files, some small/some big and a lot of folders, most of the
servers are file server for windows or linux clients). I set Spool Data = yes
and Spool Attributes = yes for all jobs and also add the line following line
the the bacula-fd.conf on the Windows hosts (which improves the speed from
about 25 MByte/s to 36 MByte/s)
Maximum Network Buffer Size = 32768 # More Speed, see
http://www.bacula.org/en/dev-manual/main/main/Client_File_daemon_Configur.html
What could be the problem? Is the performance much better in newer versions?
Other tweaks I can set? John Stoffel comes with the idea to split the client
into multiple Jobs with different FileSet to run some concurrently, see [1].
Has anyone experience with this setup?
Thanks for your help,
Patrick
