Backing up multiple servers using backup exec

[TheCrazyTechnician]

I'm currently trying to change our crap backup routine, using WIndows Server 2008 R2 backup.

 

I want to use Backup Exec but have a question, apologies in advance if it seems like an obvious or daft question. I'm completely new to backup exec.

 

I have two servers. One DC and one FILE /SIMS/FMS server.

 

Now, is it better to run separate installs of backup exec on each server? or run one instance, on a third server and use that to back up the two main servers, over the network?

 

I hope that makes sense.

We've always run one instance backing up, up to 9 machines. Initially we had 1 LTO3 tape drive then 2 LTO3 drives.

That was being strained so our new DC has an LTO5 drive which now covers the two DCs and the old instance covers the remaining 4 servers
