[CentOS] your advice on backup procedure

Hello all, I am down to my last hurdle of my project, backups. I am thinking of three different ways to go and wanted to ask for input on what you think is the better choice. Not asking for 'how to' but more of 'what is best in your experience' The scenario... centos server acting as a virtual ho
