[Time Machine] What is the default backup path?

My YunoHost server

Hardware: Raspberry Pi (4) at home
YunoHost version: 11.2.11.3
I have access to my server : Through SSH and through the webadmin
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no

Description of my issue

I have been using Time Machine since a few months and I’m having same blank screen issue described here: Time Machine Shows Blank screen under Applications
So I uninstalled time machine through SSH which was successful but all the backups of time machine still remain and take alot of space in my drive.

My question is, where does the time machine keep the backups, what is the default backup path so I could delete the directory and free space.
Thanks in advance.

Deleting timemachine folder under yunohost.app solved the issue.
