Скрипт бекапа баз mysql

Скрипт выполняет бекап всех баз, за исключением системных (mysql,performance_schema,information_schema,sys) с локального сервера mysql в отдельные файлы, и потом отправляет бекапы на FTP. Также скрипт удаляет с FTP старые бекапы, если их количество превышает заданное.
Для работы нужны pigz и lftp.

#Get list of directories with full encrypted backups

dirs=(${dirs// / })
#check number of directories and delete oldest
if [[ ${#dirs[@]} -gt $backup_depth ]]; then
        for ((i = $backup_depth; i < ${#dirs[@]}; i++))

                echo "lftp -e 'set ssl:verify-certificate no ssl:check-hostname false net:connection-limit 4; rm -r -f ${dirs[$i]}; bye;' ftp://$username:$password@$ftpserver" | /bin/bash
