InnoDB
-
XtraDB
-
MyISAM
-
MyRocks
It does not support backups on MySQL 8.0 or 9.x servers.
Percona XtraBackup 8.4 can take full backups of databases using the MyRocks storage engine.
Limitations¶
Percona XtraBackup 8.4 does not support backing up of databases created in versions before 8.4 of MySQL, Percona Server for MySQL or Percona XtraDB Cluster.
Incremental backups for MyRocks are not optimized. Each time you run an incremental backup, all MyRocks files are copied, even if they haven’t changed since the previous backup.
InnoDB tables are locked while copying non-InnoDB data.
