Question

I have big database and I would like to backup archive data tables and restore if need client request in future.
table space is over 400GB
Pls help advice.
here's my archive table size

Answer 1

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.

Answer 2

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.

Answer 3

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:
