1, solr版本相同: backup,restore
- a, solr stand-alone （速度很快，solr cloud 需要备份多个core数据才完整): https://solr.apache.org/guide/6_6/making-and-restoring-backups.html
#location=/tmp/solr-export3: 该磁盘目录不需要创建
#ip:端口/solr/集合名/replication
#备份
curl 'http://test-c6:8983/solr/jcse/replication?command=backup&location=/tmp/solr-export3&name=jsce.bak&wt=json'
[root@test-c6 solr]# du -hs /tmp/solr-export3/snapshot.jsce.bak/
48K /tmp/solr-export3/snapshot.jsce.bak/
[root@test-c6 solr]# ls /tmp/solr-export3/snapshot.jsce.bak/

#还原
curl 'http://test-c6:8983/solr/jcse/replication?command=restore&location=/tmp/solr-export3&name=jsce.bak&wt=json'
- b, solr cloud （速度很慢，不如导入导出快）: https://solr.apache.org/guide/6_6/collections-api.html#CollectionsAPI-backup
#备份： collection 配置和数据+ zk 数据
curl 'http://test-c6:8983/solr/admin/collections?action=BACKUP&collection=test2&location=/tmp&name=test2-collection.bak'
You have mail in /var/spool/mail/root
[root@test-c6 ~]# hdfs dfs -ls /tmp/test2-collection.bak

2, solr版本不同：导出/导入json
