We basically create a backup folder (our assets and MySQL Dump, then rsync it to rsync.net). Our source code is already on git, so basically backuped on Github, and all developers computer.
On top of it, rsynch has a very clear and simple documentation to implement it very quickly with any Linux distrib.
I hope that you know that your account, like all accounts at rsync.net, is on a ZFS filesystem.
This is important because it means that inside your account, in the .zfs directory, are 7 daily "snapshots" of your entire rsync.net account, free of charge.
Just browse right in and see your entire account as it existed on those days in the past. No configuration or setup necessary. Also, they are immutable/readonly so even if an attacker gains access to your rsync.net account and uses your credentials to delete your data, the snapshots will still be there.
Not sure I'd agree there, but it's not inscrutable. I use rsync for almost all file transfers, backups included, so I'm used to it. But there are oddities here and yon.
