Linode Syncing two servers on Linode?

I have searched everywhere on how to setup two linodes and sync them. I can't tell you how many articles I read with information like, "just setup two nodes and sync them and then use the load balancer." Ok, where is the guide to sync two nodes on Linode? A guide that I know will work and I won't lose my data.

It seems online that everyone has an opinion on what to use. csync, incron, gluster servers and clients, rsync, etc.

Can anyone point me to a guide for syncing multiple Linode nodes?

Vultr has a guide from 2014: https://www.vultr.com/docs/setup-file-mirroring-using-rsync-in-debian-ubuntu

Any help would be much appreciated.
