As my Linux is a bit rusty please allow me a silly question.
I am about to perform a long-overdue upgrade from V57a / 18.04 to V71 / 22.04. So I need to make a backup first and get these files off the current instance and then back onto the new instance, via a (Windows) PC.
I run into the problem that when I use Filezilla (keyfile login) I am only able to log in as user ubuntu. And this user does not have access to /home/user-data. Using Putty one would sudo up and get access but that is (afaics) impossible in SFTP.
My question, is the best way to move the backup files to and from a directory that user ubuntu can touch, or are there currently better ways to move these files to and from a PC to a MIAB instance?
