I’ve recently sufficiently mastered rsync to use it everywhere, constantly.

ESXi doesn’t have rsync bundled, cause you know, when 16GB flash drives cost $8, you need to keep your hypervisor footprint down to a few MB? I dunno.

Anyway, here’s where to download a build of rsync that’ll work on there: http://damiendebin.net/blog/2013/12/06/esxi-5-dot-1-and-rsync/

I just SCPed the file over in to my /opt/ and then symlinked it in to my path.
