How do I maintain a single up to date backup of our Exchange 2003 server onto a remote computer, connected over the internet?
We still take nightly backups onto tape but we want something completely automated. Set it and forget it. Our tape backups are also becoming increasingly unreliable due to the age of the tape drive and we are not in the best financial situation to replace it. Free or cheap software is a necessity, unfortunately!
We use a standard ADSL connection, so backing up the 30GB worth of database files over the internet each night is obviously not an option, nor is it likely to be an option to do it each week either. One single database file is 19GB on its own.
There must be a way of taking incremental backups, pushing these changes over the internet to a remote computer using a VPN connection which then merges the changes into a single backup file.
How would I do this?
