Bookstack - Backup and Root Folders

I’ve been playing with the Bookstack add-on and have been making a recipe system. But before i go any further i wish to backup all my files and bits.

Navigating to my HA samba share i cant see any files or pictures that I have added. Could anyone help with locating these. I have looked at the bookstack site and the following command are listed but i’m not sure where these should be used?

The following command will create a compressed archive of the above folders and files:

# BookStack v0.13+:
tar -czvf bookstack-files-backup.tar.gz .env public/uploads storage/uploads

# BookStack v0.12.* and below:
tar -czvf bookstack-files-backup.tar.gz .env public/uploads
1
# BookStack v0.13+:
2
tar -czvf bookstack-files-backup.tar.gz .env public/uploads storage/uploads
