Backing up and restoring SQL databases is a key operation to prevent data loss and system failure. 1. Use SSMS to visually back up the database, select complete and differential backup types and set a secure path; 2. Use T-SQL commands to achieve flexible backups, supporting automation and remote execution; 3. Recovering the database can be completed through SSMS or RESTOREDATABASE commands, and use WITHREPLACE and SINGLE_USER modes if necessary; 4. Pay attention to permission configuration, path access, avoid overwriting the production environment and verifying backup integrity. Mastering these methods can effectively ensure data security and business continuity.

There is no absolutely optimal MySQL database backup and recovery solution, and it needs to be selected based on the amount of data, business importance, RTO and RPO. 1. Logical backup (mysqldump) is simple and easy to use, suitable for small databases, but slow and huge files; 2. Physical backup (xtrabackup) is fast, suitable for large databases, but is more complicated to use. The backup strategy needs to consider the backup frequency (RPO decision), backup method (data quantity and time requirement decision) and storage location (off-site storage is more secure), and regularly test the backup and recovery process to avoid backup file corruption, permission problems, insufficient storage space, network interruption and untested issues, and ensure data security.
