datadomain (vmax&protectpoint) - how to tapeout?

good morning,

not sure it this is the correct forum, but i suppose that it is due to the fact that the specific protectpoint is not existing..anyway:

i have a vmax using protect point to backup using snapshot to datadomain, which function/software also i need to tepe out those backup? networker, or the protect point itself will take care of everything?
