TBMR backups and databases

Good morning - I am new here, and have a quick question. We currently use tdp for restoring our SQL backups to the server, but we also take TBMR backups weekly of these servers. Will TBMR backup active database files or is it strictly for OS/Server level file recovery and then would need to use a tool like TDP to restore the database once the server is up and running?

Thanks in advance for the help.
