Permanently mount HDD as Snaphot-Folder for Back in Time

I have installed different hard drives in my PC. I only use one of them for backups.

After every computer start I mustn't forget to mount this hard drive by clicking in the file manager.

Then the error messages from the backup tool (Back in Time) disappear.

Of course I would like to automate this mount. So here's my attempt.

One idea to achieve this is to add a new line in the configuration so that the hard disk is already mounted when the system starts.

I am worried if I can break something if I enter something wrong? I thought about the following

Ma Plan add a line to /etc/fstab

UUID=e2804d5dxxx/ ext4 errors=remount-ro 0UUID=F054-xxx /boot/efi vfat umask=0077 0 1/swapfile none swap sw 0 0

$ sudo blkid /dev/nvme0n1p2/dev/nvme0n1p2: UUID="2398230e-xxx" TYPE="ext4" PARTUUID="400a056e-xxx"

My planed new line in /etc/fstab

UUID=2398230e-xxx /media/m/2398230eXYZ ext4 defaults  0 0

I am worried if I can break something if I test it and not sure if its right. So i asking before. Thanks.

By the way. There's a very similar question here: 1022657/permanently-mount-hdd
