AS Java and Database backup: how?

Hello Experts,

I am attempting to update our Sap Solution Manager system to EHP1 SP18 using SAINT / JSPM.

One of the steps for preparing the system for the update (of the JSPM) is to take a backup of the SAP NetWeaver Application Server (AS Java) and of the database.

Can anyone give me some indications on how to perform these steps? Is this done via a transaction?

Many thanks,

Aldo
