Hi guys , I have centos 7 on my physical server machine and want to make another machine or virtual machine with same setting data and everything from the old one to keep it in case i got server crash or at least to make virtual copy of it . i read about make vmware convert but it needs Vspher to do it when i dont have . so is there any better way to resnyc or anythingto get all runing service and installed application in both ? one more thing is centos i have now installed on 3TB hd but the used is less than 100gb so i can make the virtual copy with the only used space or i have to make it for the same hd size ? thank you .
