What is IBD file MySQL?
An IBD file is a MySQL table created by the InnoDB database engine. It contains a table-specific tablespace and index data. IBD files are often encrypted, meaning their data can be accessed only using the keys generated when a user created the database that created the IBD file.
How do I restore an IBD file?
Recovery Methods
- Step 1: Recreate the structure from the FRM files. MySQL provides a tool named “mysqlfrm” to recreate the table structure.
- Step 2: Recreate the table in a new database.
- Step 3: Remove the new IBD file.
- Step 4: Copy the old IBD file.
- Step 5: Reactivate the table.
How do I restore a table from a.ibd file?
On your MySQL Command, go into your database, and enter “ALTER TABLE table_name DISCARD TABLESPACE”, which will essentially remove this table’s .ibd file. Copy your original table (the table you want to restore)’s .ibd file into the newly-created table to replace the .ibd file that you just removed.
Where does the IBD file go in MySQL?
IBD is a file type or extension associated with MySQL-InnoDB. InnoDB has a feature called ‘multiple table space’ that allows all tables and indexes to be stored in their own file so each table can use its own table space. If you enable multiple table spaces, InnoDB will store each newly created table in a *.ibd file in the database directory.
How to restore data from.ibd and.frm files?

How can I restore a table from InnoDB?
If you update or delete a table with a table-specified table space, it can be restored by following a few simple steps or through a DROP TABLE, TRUNCATE TABLE, or DROP DATABASE statement too. InnoDB uses the ib_log file to restore data. It requires the ibdata1 file that contains the data dictionary.
