* mysql::backup backuprotate parameter sets the number of backups to keep, default is 30. * Use bash in mysqlbackup.sh to get exit status of mysqldump when piped to bzip2. Unfortunately there is no easy portable way to do that. * Only delete old backups when current backup finished successfully. * Try hard not to delete files that we didn't create (i.e. README or other backups).
