disable zimbra backup?

(I'm running Zimbra Starter Edition 8.0.2 on Ubuntu 12.04 64-bit LTS)

So, I just installed the ZeXtras suite. Very awesome software. Everything is up and running, licensed, etc etc.

Do I need to disable the native Zimbra Backup? If so, how do I do that? Doesn't seem to be intuitive? I think the answer is to run zmschedulebackup -F, but I want to make sure..

Thanks!
