总结：
Docker环境的下的clickhouse备份，不能使用clickhouse-backup，因为clickhouse-client只能备份Docker环境下的clickhouse的元数据
Docker环境的下的clickhouse备份，可以使用TCP的clickhouse-client的9000或HTTP的8123连接clickhouse服务器后使用backup\restore命令来备份\恢复

实践过只能备份元数据，因为clickhouse-backup远程备份，只能备份元数据

使用clickhouse-client的backup和restore执行备份恢复
1、使用http的模式
[dailachdbud005 ~]# cat /root/backup_clickhouse.sh
#!/bin/bash
export CURRENT_TIME=$(date -u +"%Y%m%d%H%M%S")curl 'http://localhost:8123/?add_http_cors_header=1&default_format=JSONCompact&max_result_rows=1000&max_result_bytes=10000000&result_overflow_mode=break' \-H 'Accept: */*' \-H 'Accept-Language: en-US,en;q=0.9' \-H 'Authorization: Basic b25lmU6T2RzMjAyMg==' \-H 'Connection: keep-alive' \-H 'Content-Type: text/plain;charset=UTF-8' \--data $'BACKUP DATABASE etl TO Disk(\'backups\', \'etl_latest.zip\') \n\n\n' \--compressed \--insecure
sleep 1;mv /var/lib/docker/volumes/root_clickhouse_backup/_data/etl_latest.zip /var/lib/docker/volumes/root_clickhouse_backup/_data/"$CURRENT_TIME"_etl.zip&
sleep 1;mv /var/lib/docker/volumes/root_clickhouse_backup/_data/"$CURRENT_TIME"_etl.zip /mnt/clickhouse_backup/&
2、使用tcp的模式
查看备份路径
[dailachdbud005 ~]# clickhouse-client -h dailachdbud005 -u onescore --password '123456' --port 9000
select name,path,type from system.disks;

[dailachdbud005 ~]# cat /root/script/clickhouse-client_backup.sh
#/bin/bash
current_date=`date +%Y%m%d`
clickhouse-client -h dailachdbud005 -u onescore --password '123456' --port 9000 -q "backup database import to Disk('backups','import.zip');"
clickhouse-client -h dailachdbud005 -u onescore --password '123456' --port 9000 -q "backup database prime to Disk('backups','prime.zip');"mv /var/lib/docker/volumes/root_clickhouse_backup/_data/import.zip /var/lib/docker/volumes/root_clickhouse_backup/_data/import_$current_date.zip
mv /var/lib/docker/volumes/root_clickhouse_backup/_data/prime.zip /var/lib/docker/volumes/root_clickhouse_backup/_data/prime_$current_date.zip查看备份是否成功
