I have some servers and VPSs to many companies across the world. I want to back them up locally. I have some backup solutions enabled to remote hosts, but I want to have a local backup on a computer at home.

What I am thinking is:

1) Create a virtualbox virtual machine, install the same version linux as the server.

2) Use rsync to backup the server to the local virtualbox machine. (something like rsync -av --delete --progress --exclude '/dev/' --exclude '/proc/' root@server_ip:// / )

3) Repeat the command every few days update files.

4) In case of a hard disk failure, or any other bad event, reverse the rsync command and get the files back and continue my bussiness.

I tried it with 2 openvz VPS, the one was a backup of the other. I also tried to transfer normal linux server host to openvz machine and it worked great.

That way looks pretty clean and easy to me, this is the kind of solution I am looking for. However I need to be sure that this will work if I am going to do it.

The question is, will that work ok ? Does anyone see any problem with that ? Do you have any other suggestions ?

Thanks
