Backup history when you perform backup from slave

Hi,

I’m using innobackupex to perform full and incremental backup from master and also from slave. As the PERCONA_SCHEMA.xtrabackup_history table a innodb table, it cannot be updated on the slave so how can we have a backup history table on the slave doing as MySQL Enterprise Backup does: the backup history table is a table based on CSV engine so it is not replicated and not transactional so the backup tool can write into it on the slave.

Thanks

Christophe
