MII 12.2 Backup Solutions

I am working on a small MII 12.2 implementation, I am curious about backup solutions that other admins maybe using. I am aware of Netweaver level backups, but do not know too much about them. My feeling is that for a small implementation though this approach would involve backing up gigabytes of Oracle databases and netweaver configuration for maybe a hundred megabytes at most of MII Projects. I was thinking of imaging the whole server on a monthly basis and then taking a nightly backup of Projects, transactions, Pages, Query Templates etc. I assume this is relatively straight forward to do with a transaction ? I assume I would also not need to retain the oracle logs.

What I would like to know is it possible to also backup configuration for data servers and users.
