In the system tab you can export the current settings to a profile. If you work with different profiles you have to save them separately.
To keep the aquasuite settings you can copy the folder C:\ProgramData\aquasuite-data (might be hidden).
Currently I only have one profile, and I do save it every time I make a modification.
And I have the C:\ProgramData\aquasuite-data folder included in my daily cloud-backup procedure, so I am covered there.
But does that give access to the aquaero settings (virtual sensors. alarm settings, flow calibrations, etc), in case I have to replace the aquaero?
