Sync 2 Systems

hi there

i have a virtual Test server with Fedora on it at work.
the server is not in a seperated private network.

i want to sync all settings from the server to my laptop so i can work at home too.

i plan to install multiple services on the VM like apache, SQL-Server, bind, ...

anyone got an idea how to do this?

Do you want the virtual machine copied to your laptop or do you want the contents of the virtual machine copied to your laptop?

If you're talking the later then it's fairly easy to setup with an application like rsync. If you're talking the former you would just setup rsync to sync only that specific directory.

i was thinking about both directions...

is it possible?

Either way is easily doable.

Code:

/usr/bin/rsync -W --delete-during --stats -avrpPe ssh /* root@computer-to-be-overwritten:/ --exclude=/etc/hostname --exclude=/var/lib/mysql --exclude=/etc/network/interfaces --exclude=/etc/lilo.conf --exclude=/etc/grub.conf --exclude=/etc/raidtab --exclude=/etc/modules.conf --exclude=/etc/fstab --exclude=/etc/modules --exclude=/etc/lvm* --exclude=/etc/udev/rules.d/z25_persistent-net.rules --exclude=/proc --exclude=/sys --exclude=/dev --exclude=/boot --exclude=/etc/sysconfig/network-scripts

I may be forgetting a couple excludes there, but that is the gist of copying a system to a system over an encrypted ssh link. You basically want to exclude anything that would be more accurate on the new host, modules, fstab, and directories that don't make any sense to include-- proc, sys, dev, etc.

If you wanted to say just sync the vmfiles themselves you could do that by just specifying the source and destination as the correct locations.
