介绍

InfluxDB自带influxd命令同样支持数据备份和恢复，备份的时候分为meta、manifest、数据；下面介绍下实际操作

1.导出本机数据备份

备份数据库：monitordb
备份存储目录位置：/data/backup

influxd backup -portable -database monitordb /data/backup

指定远程主机备份参数
    • -host 192.168.1.6:8086
    • -database monitordb #指定要备份数据库，如不指定默认全部
    •  -portable     #兼容更新版本influxdb的备份文件格式，官方建议使用
    •  -start <timestamp>#指定需备份数据开始时间戳-start 2015-12-24T08:12:23Z
    • -end <timestamp>  #结束时间戳 -end 2015-12-31T08:12:23Z

2.导出远程主机备份

influxd backup -portable -database zabbix -host 192.168.1.5:8088 /data/backup

2018/11/24 17:52:58 backing up metastore to /data/backup/meta.00
2018/11/24 17:52:58 backing up db=zabbix
2018/11/24 17:52:58 backing up db=zabbix rp=autogen shard=2 to /data/backup/zabbix.autogen.00002.00 since 0001-01-01T00:00:00Z
2018/11/24 17:52:58 backup complete:
2018/11/24 17:52:58     /data/backup/20181124T095258Z.meta
2018/11/24 17:52:58     /data/backup/20181124T095258Z.s2.tar.gz
2018/11/24 17:52:58     /data/backup/20181124T095258Z.manifest

3.恢复数据

恢复本地数据

influxd restore -portable -db zabbix /data/backup/
2018/11/26 05:03:42 Restoring shard 8 live from backup 20181125T205756Z.s8.tar.gz
