LOST all my apps/files. Resets without my permission.

[Chelsea_Rose]

A couple of months ago I turned on my laptop to find all my apps and files had gone and I was unable to recover them. I regained what I could through icloud. then only a few days later the same thing happened and I believe this was due to an update that took place. following this I backed up my things incase this happened again. 

today I opened my laptop to find the same happened again and despite backing up my laptop nothing is available for me to recover. this is becoming annoying as I have important files/documents and its like setting up a new laptop everytime I use it. 

if anyone could either prevent this, help me to restore my things easily or back up incase this happened again.

Thank you
