Hello,

I had this kind of problem because of the compression.

Hi, I'm having extremely slow performance when backing up, a 10gb backup took around 3h. Where should I start looking?

During a backup I can see bacula-sd using 100% cpu, memory usage is normal. My system is a vmware virtual machine with a cpu with two 2,5ghz cores and 2gb ram. The vm have a separate partition for the volumes using ext4 and mounted via RDM in a fc storage array with raid6. I tried mapping more cores and more ram for the vm with the same result so I don't think the problem is lack of resources.

Thanks.

Hi Rodrigo,

giving more informations like

  *   version of the director, storage, fd
  *   which database back-end are you using
  *   did you install the vmware tools ?
  *   which operating system (version) are using ?
  *   on what kind of storage does your DRM point to (sata, iscsi, fc, etc.)
  *   etc.

will give us more ideas to troubleshoot your problem.

Regards

Davide

Director: 5.0.1-1ubuntu1
Storage: 5.0.1-1ubuntu1
FD: 5.0.1-1ubuntu1 (some clients have lower version)
Database: mysqI
OS: Ubuntu 10.04.4 x64 Server
FC Storage 4 GBits/s.
All my network is Gigabit Ethernet.

One question: can vmware tools have any influence in this case? From what I know vmware tools is mainly for better graphics performance  isn't it? I din't installed it.

Thanks
