mysqldump — SQL dump to a single file. This is the easiest backup method but it is not appropriate for large data sets.
xtrabackup — Full backup to a single tar file. This will take longer to take the backup and to restore.
The default backup tool can be changed, and different tools can be used explicitly when the backup command is executed. The Percona xtrabackup tool can be used to perform both full and incremental backups. Use of the this tool is optional and can configured during installation, or afterwards by updating the configuration using tpm .
