Supported storage engines¶

Percona XtraBackup 8.1 supports the MyRocks storage engine. An incremental backup on the MyRocks storage engine does not determine if an earlier full or incremental backup contains duplicate files. Percona XtraBackup copies all MyRocks files each time it takes a backup.
Limitations¶
Percona XtraBackup 8.1 does not support making backups of databases created in versions before 8.1 of MySQL, Percona Server for MySQL or Percona XtraDB Cluster.
