Explain MySQL's binary logging and its formats.

Binary logs record all changes for replication and point-in-time recovery.

Formats:
• STATEMENT: Logs SQL statements
• ROW: Logs actual row changes
• MIXED: Automatically chooses format

Configuration:
log-bin=mysql-bin
binlog-format=ROW
expire_logs_days=7

Example:
SHOW BINARY LOGS;
mysqlbinlog mysql-bin.000001
