Backup Percona XtraDB Cluster or Galera Cluster with TwinDB
Database servers and clusters should be backed up regularly to prevent data loss when an error or disaster occurs. You can backup database servers logically using mysqldump, but you can also backup databases physically using Percona XtraBackup. XtraBackup enables you to run full and incremental backups, stream backups, compress and encrypt backups. TwinDB has simplified the usage of Xtrabackup and will automatically backup your Percona XtraDB cluster on an hourly basis.
