Restore from backup | MySQL

Question

I have restored from a backup on a specific date to a test server database and I want to check if it restored all the data. How can I check or compare the data between the test database and the production database.

Answer 1

Welcome .

This would have become a good post (for several others) if you had added little more details.

Assumptions .

1. Original database at first server is bigger and the restored database in second server is a subset (backup on a specific date).

2. So many databases, so many tables, so many columns and so many rows.

Solutions .

1. Your backup (bet it through your own script or through a tool) should have an accompanying log file. Refer the same for any errors / warnings.
2. Refer the outcome of your restore too. And if both does not have any thing unusual, you can be sure of (may be 95%).
3. Prepare a script to have output from both servers having group ed sum values based on important criteria / categories / group heads / etc.
4. Also run this. https://dev.mysql.com/doc/refman/5.7/en/checksum-table.html on both servers.
