I need a solution
Master & two media servers running Windows 2003 & Netbackup 7.0.1
i80 tape library with 4 LTO5 drives
139 active backup clients mix of Windows 2000, 2003, 2008, Linux, Solaris, and 25 TB NDMP
The customer is adding more hosts to the backup schedule which is starting to slow things down a bit. I will have to start multiplex / multistream jobs in order to complete backups in the windows I have been given. I have seen where you can over multiplex / multistream and actually hurt performance.
I have standardized retention to diff's 3 weeks, fulls 3 months and monthly fulls 1 year on all jobs. Based on the current setup what would be a middle ground to use on multiplex / multistream?
