Hello,
The situation is this:
An training environment where all servers are virtual and I have no physical access to the servers.
Is it possible to backup the Debian email server over the network to another server in case the original server is compromised beyond repair.
I would need to be able to recover from the saved backup as well.
You can copy a machine live using "rsync" command.Quote:

I use as well rdiff-backup which is a program to allow you to keep copies of differences.
I copy the entire server then I make additional backups of that server every night to a rdiff-backup folder
rdiff-backup is not required but in case you want to revert mistakes it will keep copies of them.Code:rdiff-backup /Production /BACKUPDRIVE/productionwithrdiff/

There are some excellent tutorials here:Quote:
