Please may I have help? :)

Okay, well i've been running a vanilla server for the last 13 days, and it's getting very popular, so i've decided to seek 24/7 hosting, i'm going to go for the zombie package from beastnode (https://www.beastnode.com/portal/cart.php?gid=10), and i'm scared about leaving the server unattended, because we have been griefed before, and I was wondering if the zombie package has a "rollback feature" and if it dosen't could someone please point me in the right direction?, Thank you
