Backup and Recovery
Question
Is it true that binary backups always take less space than text backups?
Options
- AA. No, because binary backups only contain data, and not statements required to insert data into the tables.
- BB. No, because text backups can have optimizations, which make them smaller, such as updating many rows at once.
- CC. No, because if InnoDB tables contain many empty pages, they could take more space than the INSERT statements.
- DD. Yes, because even if InnoDB tables contain many empty pages, text backups have empty INSERT statements for them.
