    You can not backup single table, only the complete database.
    You could create a separate database with that archive data/table and create in prod database a view with a cross-database query to archive database.

    Hi LilyJune-5583,

    Agree with Olaf.

    It is not supported to backup specific tables to a .bak file currently.
    You can use alternative ways to copy specific tables to flat files or other databases.
    Please refer to the following articles which might be help:

    Huge/Large SQLSERVER Table to .BAK file

    Step 1 : Create a new DEMO database.

    Step 2: Use import/export wizard, copy the huge table from Production Database to DEMO database.

    Step 3: Take the backup of the DEMO database. This DEMO.BAK will contain only the backup of the large table data.
