My mom is ready to move to linux, but since I'm a newbie myself, I need to ask you for help with this:
Apart from mails and surfing, she also uses her pc to back up her phone pictures. She copies them to her pc ad there's an external hard drive connected to it. We set up automatic mirroring of the files from the pc to the external ssd. So she basically doesn't have to take care for it except dropping her files to her computer.

I'd appreciate any help with this :)
