Yes, we use the VMWare ESXi environment. We *love* it. Virtualization is just flat-out amazing.
I noticed both Bert and Sandeep mentioned Macrium. I will have to look into it. Generally speaking, when either of those two characters talks, I listen, lol. And Sandeep gets another vote of "numero uno" from me.
Chris @AC - thanks for taking the time to look into this. Yours is a tough gig, and we appreciate you.
Lol yep, but for those that have VM's, it's good to know it's as easy as copy and paste. I believe Gianni (thread OP) uses VMWare. For people who have it on physical hardware, I also tested both Macrium and Acronis and confirm it works. BUT! If you are cloning to new hardware, you will need to use Universal restore (Acronis) or Redeploy (Macrium).
Full server image backups should be the preferred way in case of server failure. That way you can restore all services at once. AC data backup is a backup-backup for me. It's hard to backup full disk images to the cloud, but data files are pretty easy.
