I'm very pleased to announce that a new Maintenance Release for NetBackup 7.1 is now available!

In addition to many bug fixes, NetBackup 7.1.0.2 contains several changes that can improve restore performance and rehydration performance. This feature offers the following enhancements:

  • Rehydration improvements for deduplicated files
  • Environmental factors that affect rehydration performance
  • Changes and updates to the deduplication tuning parameters that affect restore performance and rehydration performance
  • Editing the ReadBufferSize parameter
  • NetBackup tuning

To download 7.1.0.2, please visit the following page:

from last one year, I have seen lots of folks (with in and outside organization) asking me about NODirectSDR registry entry or I have suggested them to use it to resolve lots of problems with flashbackup for windows policy type backups. I will get some time to post an article on that and usage info. I will update the link here as well.
Thanks,
Praveen

I mentioned this on twitter earlier today but wanted to follow it up with some additional commentary. Sometime 140 characters aren’t enough.

The Brookings Institute, a nonprofit public policy organization, released a study that compares government web sites with commercial web sites. They used a variety of measures to create a score for each of the companies and government entities studied. The resultant table is below.

Do you seldom encounter slow mapping with flashbackup?

Look at your exclude file list. Do you really want to exclude 50% of the drive? When performing Flashbackup, setting up an exclude list will decrease the performance of the VxMS mapping. The exclude list processing requires a lot of resource and time, so excluding too much data will slow down performance.for an example if you are backing up a 1TB drive using FBU, mapping should take around 35-40 minutes in usual scenario but if you have a exclude list of say about half of TB, It may take a whooping 7-8 hours in just mapping.

Finding the fish in a large pond with millions of fish and mark it not to be fished. Not a great Idea and it need too much work to do. My advice on this, not to have a large exclude list while using FBU. your Back-ups may not work as fast as it use to.
