I use ISPConfig 3. When a user ftp to server, and follow the link to his backup, he got a permission deny error. (The permission in the backup folder are root:root 755 for the folders and root:root 644 for the files) Is this normal? All the backups belong to root? Is it matter that the admin account created the users' site?
I think I confirmed it. Only root can have access to the backups. The user, can only backup his site through ftp, file by file.
