Would be nice to have our preferences backed up

I suppose one benefit might be that installations on different machines could access the same presets. 

Both Windows and Mac have built-in backup software, and there are loads of third-party backup applications, both free and paid.

Buy an external hard drive, even a slow USB model will work, and start doing backups.

@jbunds "I recently had to re-install windows, didn't have the option to back anything up, and now my settings are gone forever"

And that's the very reason I create a backup image of my SSD on a weekly basis, that way I just re-image it if things go wrong,

It's all done in about 5 minutes, all apps and settings restored to the way they were

Alas, considering the misinformed »Adobe is stealing your images«-bruha a while back I wonder what kind of nonsensical accusations might be raised when custom brushes, patterns, shapes, actions etc. were also stored on Adobe servers by default. 

There might also be size-issues for some users – abr- and pat-files can, in my experience, easily get pretty big for example.
