想要backup database dbname to Disk('diskname','backupfilename.zip')成功的话，需要符合3点

1、diskname需要在/etc/clickhouse-server/config.d/backup_disk.xml在<storage_configuration></storage_configuration>中存在

2、diskname需要在/etc/clickhouse-server/config.d/backup_disk.xml在<allowed_disk></allowed_disk>中存在

3、diskname需要在select name,path,type from system.disks结果集中存在
