Help How to backup phone?

How to do full backup of phone? (to restore phone if lost/stuck/faulty)

Does copy and paste all phone folders work as a backup? Before update can I copy and paste all phone files to PC, if something bad happens during a update then copy and past all phone files from PC to phone?

Is there android backup software that work, maybe also auto schedule backup? No root.

What do you do before doing an update? Any backup or tips to ensure successful update?

Thanks

What phone do you have? Some manufacturers have their own utility program that can backup the phone. For example I use Samsung's SmartSwitch to periodically backup my phone.

You don't have to backup anything if there is an update, Android doesn't erase anything.

I have Samsung Galaxy Note 8.
What if the update fails and corrupt the phone (e.g. black screen, stuck, unable to access something...)? Is there a way to rollback/uninstall the update?
For example in PC there is a way to full backup and roll back to previous version if the Windows update fails or weird stuff happens after the update, I am thinking of similar backup in Android.

Use Samsung's Smart Switch utility. It's Samsung's multi-function service that includes a handy backup and restore feature:

And no, just copy-and-pasting as a backup solution will not suffice. There are a lot of things that are in hidden, protected directories that will be skipped using just drag-and-drop copying. And that's even less effective since your PC running Windows is so limited as far as native support for other platforms (i.e. your PC is running Windows and relies upon NTFS as its file system, your Android Note is running Android and that runs on top of ext4).

as suggested by @svim , use Samsung's SmartSwitch to backup your phone. you can even save the backup to your computer.
