*  1, solr版本相同: backup,restore
 *  2, solr版本不同：导出/导入json

# 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][https_solr.apache.org_guide_6_6_making-and-restoring-backups.html]

# location=/opt/solr-export: 该磁盘目录的属主需要为solr:solr 
    # ip:端口/solr/集合名/replication
    #备份
    mkdir /opt/solr-export; chown -R solr:solr /opt/solr-export
    curl 'http://test-c6:8983/solr/jcse/replication?command=backup&location=/opt/solr-export&name=jsce.bak&wt=json'
    
    [root@test-c6 solr]# du -hs /opt/solr-export/snapshot.jsce.bak/
    48K     /tmp/solr-export3/snapshot.jsce.bak/
    [root@test-c6 solr]# ls /opt/solr-export/snapshot.jsce.bak/

    #还原
    curl 'http://test-c6:8983/solr/jcse/replication?command=restore&location=/opt/solr-export&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][https_solr.apache.org_guide_6_6_collections-api.html_CollectionsAPI-backup]

#备份： collection 配置和数据+ zk 数据

    You have mail in /var/spool/mail/root
