if I have a VMware ESXI environment which has 4 physical cpus and consist of 24 TB or storage and 50 VMs. what license I will be needing to protect it? also I believe NBU license is base on tier level. is there a document for it?
Besides the NetBackup Server license you will need:
One Enterprise Client license for each physical host when one or more resident VMs are protected by NetBackup for VMware.
One Application and Database Pack license for each physical host when one or more resident VMs are protected by any of:
For example, a single physical host running multiple virtual machines including Exchange and SQL Server would require one (1) Application and Database Pack license to cover all Exchange and SQL Server instances on the physical host, regardless of how many VMs may be running these two applications.
Enterprise Client and Database Pack are based on Tiers.
The document you are asking for is named "Netbackup Licensing Guide", your account manager could provide it to you.
