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:

    1) This seems like it would be difficult to get. How would I go about getting this information?

    2) We do daily incremental backups and fulls on the weekend. The fulls on the weekends are retained for 30 days except for the first weekend of each month...those fulls are retained for 1 year with a few being retained for 7 years. Those backups are done and duplicated to tape and sent offsite. The incrementals are retained for 30 days.

    3) Incrementals = 30 days / Weekend Fulls = 1 year / First weekend of the month Full is either 1 year or 7 years

    4) Not really sure how to answer this. The 30 day stuff is written to tape and thats it. Our goal is to get that stuff on disk and then replicate it to a remote site to cover our offsite storage requirement. Some of the SLP's are set to backup to disk and keep it for 2 weeks and then duplicate that to tape which is then retained for a year.

    5) That is kind of up in the air and all over the place here. Nothing very definitive.

    My primary goal at this time is to be able to supply my management with concreted numbers on how much disk storage space we need to get all the 30 day stuff on disk.

    Work with your Symantec partner. They have access to dedupe calculator where this kind of info along with type (Filesystem, Vmware, Exchange, Oracle, etc) is entered. It will calculate MSDP pool size for you.

    I have reached out to him in the past and he has been less than responsive and not very savvy when I did hear back so I figured I'd start here first. I will give that another shot.
