TencentDB for MySQL ensures the confidentiality and integrity of data during storage.

Automatic backup

TencentDB for MySQL supports both automatic and manual backup to ensure data restorability that guarantees data integrity and reliability. It provides data backup and log backup features by default, where the frequency of automatic backup should be set to more than twice a week. If you have other backup needs, you can initiate manual backup through the console or APIs at any time.

Archive backup retention

TencentDB for MySQL allows you to enable archive backup retention. You can flexibly configure the retention period of backup files as needed, which is 7 days by default and can be up to 1,830 days. Backup files that exceed the retention period will be automatically deleted. For data security considerations, we recommend you back up your data at least twice a week.

Transparent data encryption

TencentDB for MySQL supports the transparent data encryption (TDE) feature developed by the Tencent Cloud database team. Transparent encryption means that the data encryption and decryption are imperceptible to you. When creating an encrypted table, you do not need to specify an encryption key, and the data will be encrypted during write to the disk and decrypted during read from the disk.

TDE uses the internationally popular AES algorithm and 256-bit encryption keys, which are managed in Tencent Cloud Key Management Service (KMS). You need to be authorized to access KMS and can rotate keys in the KMS console to further improve the system security.
