We have a very small system with VMware Essentials.
1 host (no vcenter installed)
1 virtual server
2 virtual pc's
How can we do cost effective backups in case of disaster?
Should we use Acronis?
PHD Virtual has a great backup solution that is very easy to use and install. It has a very robust set of features, as an industry leader should. I've never had any issues with it and I've been using it for years. You should never buy any software without first testing it, but I would definitely include PHD in my evaluation. Just as a side note... when I tested PHD against Acronis and Veeam head to head, PHD won hands down. It's worth the look
