I have to to set up a new Windows 2012 physical media server with NB 8.1.2 and I need the minimum and recommended requirements (CPU, RAM, etc...)
I have read the installation guide, and it sends me to the SORT site, but I don't understand how to retrieve the informations that I need
Can someone help me please?
See this planning guide, and add a bit more RAM for modern OS and and latest versions of NetBackup, eveything else pretty much still stands:
Symantec NetBackup Backup Planning and Performance Tuning Guide
Review the guide @sdo linked above - you really need to calculate how much data you plan to send through and how many destinations. Also - pay attention to how data flows - hba and network interfaces have a major impact as well.
Remember - you can have GOOD, FAST or CHEAP - pick TWO!
