介紹

InfluxDB自帶influxd命令同樣支持?jǐn)?shù)據(jù)備份和恢復(fù)，備份的時候分為meta、manifest、數(shù)據(jù)；下面介紹下實際操作

1.導(dǎo)出本機數(shù)據(jù)備份

備份數(shù)據(jù)庫：monitordb
備份存儲目錄位置：/data/backup

influxd backup -portable -database monitordb /data/backup

指定遠(yuǎn)程主機備份參數(shù)
    ? -host 192.168.1.6:8086
    ? -database monitordb #指定要備份數(shù)據(jù)庫，如不指定默認(rèn)全部
    ?  -portable     #兼容更新版本influxdb的備份文件格式，官方建議使用
    ? ?-start <timestamp>#指定需備份數(shù)據(jù)開始時間戳-start 2015-12-24T08:12:23Z
    ? -end <timestamp>? #結(jié)束時間戳 -end 2015-12-31T08:12:23Z

2.導(dǎo)出遠(yuǎn)程主機備份

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.恢復(fù)數(shù)據(jù)

恢復(fù)本地數(shù)據(jù)

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