Speeding up deduplication

Check here for new and updated technical articles (and videos) on NetBackup and NetBackup Appliances that have been vetted by a cross-functional content council of NBU product and technical support engineers. 

The first article (link above) takes a deeper dive into the NetBackup deduplication process. Read this article if you have ever wondered why:

  • MSDP is always busy, even with no jobs running
  • TLog processing takes days to complete
  • DiskVolume is down
  • You are getting Status Code 83, 84, or 2074

If you have feedback or questions on any of the articles, or if you have key topics or areas that you would like to see addressed, please comment and let us know. Our aim is to provide you with the most up-to-date technical information on the NetBackup issues that concern you most.

Hi Mette Wadleigh

When i use MSDP function, i often encount the problems as below

1. MSDP create failed, I don't know what is MSDP create wizard do,so it's hard for troubleshoot.

2.Two months ago,I want to delete MSDP from my test environment.It's take me 2 weeks to do this,i need  follow lots of TN to complete it.

3.As a netbackup adm,i know how to troubleshoot daily erros. After use MSDP function,i'm confused.

4.Our site have a 5200 box,I'm not confident to use it. it's like a black box.

Thanks

Jim
