Capacity Planning
So this is kind of a very broad question that I was hoping to just get a discussion going about. I am new to doing capacity planning, but in my new role I have to do literally everything for the environment. In my previous work locations we had a team that did all the capacity planning for drive distribution, how many tape drives were needed, tapes, disk storage size and all that good stuff. Now that this falls on me I am hoping to get some help as far as capacity planning is concerned. For starters I would like to be able to provide management accurate data on how much disk storage we need in order to put our entire environment on disk. I have OpsCenter up and running as well as an application called Splunk which can tap into any log or command output that Netbackup has or can run. At this time it seems as though all they really do here is go off of the nbdeployutil and use the charged capacity total number. I am looking for ideas/input on what I can really do to track capacity as well as growth.
capacity planning requied the inputs of
1)amount of data that needs to get backup
2) freqency of the backups
3)retenction of the backups
4) number of backup copies
5) DR requirements
once we got this imputs we need to discuss about the target devices , like disk or tape , considering the dedup devies.. etc.
i would say below T/N is the best place to start it

The nbdeployutil command could be a good starting point to help you get a handle on what your 'client side' backup foot-print is:
