By the time the TB is restored, time to start the next test

How do you detect restored but bit flipped data ?

I do this in backup testing:

    sqlite3 /path/to/db
    sqlite> PRAGMA integrity_check;
See SQLite3 documentation: https://www.sqlite.org/pragma.html#pragma_integrity_check

Sounds like it will take awhile for TB and it checks db integrity not data integrity
