We are planing to install Netbackup 7.7.2 and EMC Data Domain ( "OS: 22.214.171.124-485123Model: DD2500" ).
My query is that can we use Netbackup virtually
We required physical server ?
Considering the performance of backup.
I use data domain and find it works very well.
Of course, I am stuck with Fiber Channel due to old architechture standards, and VTL as well. Even so, they work well. I have several hundred drives defined on each one, so I can send my back ups there as fast as I can, and then I duplicate to tape using SLP.
There are a couple of things to watch out for - there is overhead on cleanup, and you need to plan for expiring and deleting the old images to free the space back up.
My processes are tape based since I am using VTL, which I do not recommend.
