Netbackup licensing

Hope this helps

I want to set up a new backup environment with 1 Master/Media server, 2 tape drives to backup  1 MS exchange server, 1 filer and 4-5 standard client servers. The data to be backed up is very less.

Presuming 2 Tier NBU Architecture (Master server itself would act as Media server and has   2 drives connected)

1 Standard server

2 Tape drive License

1 NDMP license

App/DB pack for exchange would be required  per Server (if in case you have Exchange 2010 DAG consisting of 2 Mailbox server) hence you would require 2 APP/DB pack  + 2 Standard client license for exchange

so Total comes

1 Standard  Server (Master)

2 Tape Drive

1 NDMP

2 App/DB (if 2 Mailbox server is there)

7 (5+2) Stadard clients

PS: Per App/DB you need to procure STD/ENT client license

ENT client is useful for SAN based backup

STD is for only LAN based backups
