It does take time to establish a complete back-up database, but it's a worthwhile exercise IMO for when (not, "if") the brown stuff and the fan meet - especially if you intend to use OBD11 Apps (which don't/haven't-normally recorded the before/after change values)
Another advantage of having a back-up database is that you can scrutinize the settings on your car before implementing a tweak - without the need to hook up the OBD11 dongle. Very useful if you want to see if the tweak is suitable!
