I've installed a multiserver setup with vms on a headless Ubuntu 14.04.5 LTS server. I used your howtos: https://www.howtoforge.com/multiser...se-servers-on-debian-squeeze-with-ispconfig-3 https://www.howtoforge.com/vboxhead...box-4.3-on-a-headless-ubuntu-14.04-lts-server My setup is: web & db server with ISPConfig 3 CP mail server dns1 server dns2 server that is mirror of dns1 My backups are copying and compresing the vms while running, plus backup only the data (web server /var/www/*). I wanted then to copy the vms to different backup servers, registering them and have them running with virtual network cable unplugged (setlinkstate1 off). So if the primary servers failed all it WOULD be needed is to run the command "VBoxManage controlvm name_of_server setlinkstate1 on". Problems are vms take to long to copy, uses to much space and the fs curruption is allways a possible problem. I've read the your HOWTO for backing up a running vm with special lvm partitions but I can't do that on the production server. The next idea was not to copy the whole vms every day, but have them running disconected and only copy data with rsync as mentoined in manual. But the problem is the same private IPs and hostnames. So my I'm interested what do you guys suggest for a more or less begginer in linux and servers to do. Can I use rsync between 2 vms with same IPs and hostnames, with some kind of port redirecting?! Or should I create and install new vms with different IPs and hostnames, mirror them with ISPConfig and use rsync on them as described in manual? Can I use the copies of my vms and change the hostnames and IPs so I don't need to create and install new vm servers. But I don't think it's possible because off the multiserver setup. Or is there a simpler way that I don't know? As I said I'm a begginer at linux and servers and all I know is mostly from this forum, your HOW TOs and what google knows so it's possible that I missed some other ways to make a redudant backup system.
