Very slow Disk to Disk backup

Post by heinzk1 » March 17th, 2013, 8:16 pm

I am finding that my backups are having performance issues. We are doing disk to disk backup and only achieving at most 5GB/h.
Our Sep sever is on a dedicated VMware box with 4GB of Ram and Dual Xeon processors
I am trying to backup our NSS drives on an OES 11 Sp1 server also on VMware but with 8GB ram

What should I look be looking at to make the performance jump up?

Sincerely,
Ken

Hello,

please check:

- antivirus software (on Sesam server ans OES Server)
- name resolution (DNS, SLP), same DNS server, prim. DNS server available, DNS server on another subnet -> routing
- try to add both machines to the hosts files of both machines
- check the hosts file (127.0.0.1 localhost, no wrong entries)

- use "tsatest" for checking the possible read performance on NSS filesystem
- make a Linux "path" backup ( /var/ or so) to check the non TSA backup performance
