I'm using Linux Mint 19 Tara with home folder encryption enabled. Now I want to configure home backups with backup tool, but I don't want to store backup inside home directory. I don't want to store it to external device neither (I want to have it locally and mirror it to my NAS server). I also want to have backup scheduled without need to enter password to authorize making backup, but of course I want my backup to be encrypted.
I don't know how can I create directory outside home, but inside my ssd, with permissions for backup tool to use it?
My current backup tool is default one installed with OS, it's called "Backup Tool" and in system monitor I see process name "mintbackup".
I just log in with my simple user account and press "Backup tool" without using 'sudo' so it's run as me.
So my problem is that I'm not able to point directory other than home (in backup tool, as backup destination directory), because I don't have permissions.
I just want to create some directory, for example
/var/backups/home-backup/ and allow my user to touch it without sudo, so backup tool will be able to use it.
