Elasticsearch备份数据
Elasticsearch备份数据
1、建立备份目录 POST _snapshot/my_backup/ { "type": "fs", "settings": { "location": "/mount/backups/my_backup", "max_snapshot_bytes_per_sec" : "50mb", "max_restore_bytes_per_sec" : "50mb" } } 注:/mount/backups/my_backup目录需要所有的节点都可以访问 2、备份 2.1、备份所有的index PUT _snapshot/my_backup/snapshot_1?wait_for_completion=true 注:页面会block住直到备份完成,如果需要后台进行,去掉?wait_for_completion=true 2.2、备份指定的index(index_1和index_2) PUT _snapshot/my_backup/snapshot_2 { "indices": "index_1,index_2" } 3、查看备份的数据 3.1、查看所有的备份 GET _snapshot/my_backup/_all 3.2、查看指定的备份(snapshot_2) GET _snapshot/my_backup/snapshot_2 4、删除备份 DELETE _snapshot/my_backup/snapshot_2 注:备份是增量的,不要手动删除,es提供的api会帮助你删除未被使用的snapshot 5、查看备份进度 GET _snapshot/my_backup/snapshot_3/_status INITIALIZING:初始化 STARTED:开始备份 FINALIZING:数据迁移完成但未备份完成 DONE:备份完成 FAILED:备份失败,请查看日志 6、删除正在进行的备份 DELETE _snapshot/my_backup/snapshot_3
