Hi,
I want to test restore performance and was wondering if there is a way to restore to /dev/null ?
Many thanks - Darren

This is what you are looking for :
Documentation: How to use the GEN_DATA file list directives with NetBackup for UNIX/Linux Clients for Performance Tuning
http://www.veritas.com/docs/000091135
The GEN_DATA file directive create random data in memory and store it as real data on disk or tape. But the restored data go nowhere other than memory. Perfect for performance testing.
HIGH RECOMMENDED !

Nope, not that I have heard of.

I restored /dev/null & it was really quick but nothing was there!
OK sorry, bad joke.

As to your query, you can try duplicating the image. See this old thread:

Why not just restore to an alternate location and delete the contents once you are done?
That is what I would do.

Thanks Will ;)
We have been restoring to alternate locations but we are seeing some unexplained throughput issues on a particular server and I wanted to rule the disk / I/O out.
