Netbackup -remote file servers over WAN (to do or not to do?)

[NB_noob]

We have a case where we have a central data center backing up all datacenter servers to the NBU environment.

Usually our remote sites are done via backup exec.

I was thinking about integrating the remote sites' file servers into NBU (over WAN). The only problem would be the first backup, as it would be so big (approx 50GB of data).

Are there any ways of pre-staging the data transfer with NBU? Ie, with robocopy, we can actually have the data sent over to us with an external HDD and then have the remote site file server robocopy/sync the changes...instead of having to do a huge 50GB over the WAN backup..

Or how about even having the remote site file server set up as a Media Server..?

any ideas appreciated. thanks.

You can try this. Run a Full Backiup locally on a disk or tape, bring it to your central datacenter, import the tape or restore it on a staging client (with same name) then perform backup using the same client name, remove this temp server from network. Now, you should be able to perform diff/cummulative backup directly through the remote client (not a very reliable solution, unless yoy have fat dedicated bandwidth for your WAN connection).

I suggest you should look into PureDisk.
