DP 6.2 - Backups very slow...

Jump to solution

Running DP 6.2 on Windows 2008 R2 on a HP DL360 G4 with a G2 1x8 Autoloader. The autoloader is connected via LSI U320 SCSI 2000 HBA. I have a file system backup job with about 25 Windows clients. One of the clients has about 110 GB of data on the D: drive. On the DP device config, I have the drive -> settings -> concurrency set to 24, block size set to 64 kB, segment size set to 4000 MB, and the disk agent buffers set to 24.

That one drive takes about 40 hours to back up. I'm curious if there is a device/drive configuration that will provide better performance. Thanks in advance.

Even while your blocksize should be 256k and the agent buffers could be increased to 32 have a look into the following post. In includes two omnirc variables you should set on your CS to work around possible performance issues. If you have no patches applied to the CS, this could be another reason.

Made the necessary changes that weren't alread there.  Incr1 backups do seem faster, but will follow up Monday after full backups.  Thanks again.
