How to backup and restore an InnoDB table?
MySQL Enterprise Backup (MEB) 4.0.2 is provided to support the backup and restore of Encrypted Innodb Tables. MySQL Transparent Data Encryption (TDE) is introduced in MySQL 5.7.12.
How is InnoDB table encryption handled in MySQL?
When InnoDB tablespace encryption uses a centralized key management solution, the feature is referred to as “MySQL Enterprise Transparent Data Encryption (TDE).” The following is a brief description on how encrypted InnoDB tables are handled by MySQL Enterprise Backup in backup, restore, and apply-log operations.
Can you skip empty pages on an InnoDB table?
The –skip-unused-pages option has no effect on encrypted InnoDB tables during a backup (that is, empty pages for those tables are not skipped). Offline backups of encrypted InnoDB tables are not supported by MySQL Enterprise Backup 4.1.1 and later when working with MySQL Enterprise Server 5.7.21 and later.
How does hot backup work in MySQL 5.7?
Hot Backups. The mysqlbackup command, part of the MySQL Enterprise Backup component, lets you back up a running MySQL instance, including InnoDB tables, with minimal disruption to operations while producing a consistent snapshot of the database. When mysqlbackup is copying InnoDB tables, reads and writes to InnoDB tables can continue.
Do you need MEB to backup MySQL data?
MEB is part of an Enterprise Edition and hence designed to access both File and Oracle Key Vault to backup and restore MySQL data.
What’s the best way to recover from an InnoDB crash?
Besides the flag of innodb_force_recovery, I found another solution: innodb_file_per_table, that splits InnoDB tables in each file like MyISAM tables. In a crash recovery you can lost less data than in single file ibdata1. Thanks for contributing an answer to Stack Overflow!
What kind of encryption key does InnoDB use?
MySQL TDE uses a two-tier encryption key architecture, consisting of a master encryption key and tablespace keys. The InnoDB storage engine uses the keyring to store its key for tablespace encryption. These keyring solutions are available as plugins.
