Now that I have my email server just about ready to fly, I would like to ask about server backup strategy. What is the most effective method of backing up all OS email configuration and data? I was thinking about first dumping to another machine via the network and then going to tape. If this is done, I would imagine that TAR should be used. Does this method capture all data properly? I have been looking at the DUMP command but am not 100% certain as to which is a better alternative. Are 3rd party backup applicaions a better alternative?
I would like daily complete backups if possible. I do not see this machine growing above 30 gigs any time soon.
