We create our backups from Percona Server with innobackupex in a daily cron job. It seems, that backup succeeded ("130821 15:18:34 innobackupex: completed OK!"), but after completion we get a huge e-mail containing megabytes of debug/log output from innobackupex. Is there a way to make innobackupex less verbose or to send a mail only on failure? I don't want to use "2>&1" in cron job, because this supresses failures also.
