Creating a Backup Infrastructure with best practices

Dear All,

Is there anyone who is willing to support creating a new NetBackup infrastrucure according to Symantec best pratices . My requirements or scnerio is as folow.

1- HQ Data  

2- Regional Data (from 5 offices or sites) to bring to HQ

3- RHQ . Once All data from regional and HQ are backed up we need to send it to regional HQ or DR site.

4- I would like to have one DR site,HA or clustering or 2nd master server, whatever is best in our case  within the same HQ location.  In case something goes wrong with Master server so I can  have all the configuration and can easily restore backed up data .
