[Koha] Problems restoring a backup to a new server

I am attempting to setup a new server and trying to restore the file koha_library.sql.gz to the new server. I assume that the gz is a compressed file. Using the command in the terminal "mysql -uroot -p koha_library < koha_library.sql fails with the error file not found. I attempt to tar the file with tar -zxfv and get an error that it is not a valid tar file. Running Ubuntu precise1 and koha version 3.18.11.000. All help is appreciated.
