1、备份元数据
基本语法：
influxd backup <path-to-backup>
备份元数据，没有任何其他参数，备份将只转移当前状态的系统元数据到path-to-backup。path-to-backup为备份保存的目录，不存在会自动创建。
该备份会备份所有数据库以及所有保存策略下得数据。
导出常用得其他参数：
root@704be48ac1bc:/# influxd backup -h Creates a backup copy of specified InfluxDB OSS database(s) and saves the files in an Enterprise-compatible format to PATH (directory where backups are saved). Usage: influxd backup [options] PATH -portable Required to generate backup files in a portable format that can be restored to InfluxDB OSS or InfluxDB Enterprise. Use unless the legacy backup is required. -host <host:port> InfluxDB OSS host to back up from. Optional. Defaults to 127.0.0.1:8088. -db <name> InfluxDB OSS database name to back up. Optional. If not specified, all databases are backed up when using '-portable'. -rp <name> Retention policy to use for the backup. Optional. If not specified, all retention policies are used by default. -shard <id> The identifier of the shard to back up. Optional. If specified, '-rp <rp_name>' is required. -start <2015-12-24T08:12:23Z> Include all points starting with specified timestamp (RFC3339 format). Not compatible with '-since <timestamp>'. -end <2015-12-24T08:12:23Z> Exclude all points after timestamp (RFC3339 format). Not compatible with '-since <timestamp>'. -since <2015-12-24T08:12:23Z> Create an incremental backup of all points after the timestamp (RFC3339 format). Optional. Recommend using '-start <timestamp>' instead. -skip-errors Optional flag to continue backing up the remaining shards when the current shard fails to backup. backup: flag: help requested
具体如下：
Usage: influxd backup [options] PATH -portable # 在线备份，必选 -host <host:port> # 需要备份的influxdb服务机器地址，可选，Defaults to 127.0.0.1:8088. -db <name> # 需要备份的db名称，可选，若没有指定，将备份所有数据库 -rp <name> # 备份某个保留策略的数据，未指定，则备份所有rp的数据。 -shard <id> # 需要备份的shard id，可选，若指定了备份shard，必须先选择rp -start # 需要备份的数据的起始时间，timestamp (RFC3339 format). 不能和-since一起使用 -end # 需要备份的数据的结束时间，timestamp (RFC3339 format). 不能和-since一起使用 -since # 备份这个timestamp之后的数据，建议用-start <timestamp>代替 -skip-errors # 可选，当备份shards时，跳过备份失败的shard，继续备份其他shard。
2.influxdb导入
1.先删除数据库
2.导入备份数据：
这种方式只能导入按个数据库进行导入；
3.导入其他配置项参数： root@704be48ac1bc:/# influxd restore -h Uses backup copies from the specified PATH to restore databases or specific shards from InfluxDB OSS or InfluxDB Enterprise to an InfluxDB OSS instance. Usage: influxd restore -portable [options] PATH Note: Restore using the '-portable' option consumes files in an improved Enterprise-compatible format that includes a file manifest. Options: -portable Required to activate the portable restore mode. If not specified, the legacy restore mode is used. -host <host:port> InfluxDB OSS host to connect to where the data will be restored. Defaults to '127.0.0.1:8088'. -db <name> Name of database to be restored from the backup (InfluxDB OSS or InfluxDB Enterprise) -newdb <name> Name of the InfluxDB OSS database into which the archived data will be imported on the target system. Optional. If not given, then the value of '-db <db_name>' is used. The new database name must be unique to the target system. -rp <name> Name of retention policy from the backup that will be restored. Optional. Requires that '-db <db_name>' is specified. -newrp <name> Name of the retention policy to be created on the target system. Optional. Requires that '-rp <rp_name>' is set. If not given, the '-rp <rp_name>' value is used. -shard <id> Identifier of the shard to be restored. Optional. If specified, then '-db <db_name>' and '-rp <rp_name>' are required. PATH Path to directory containing the backup files. restore: flag: help requested
主要作用：
Usage: influxd restore -portable [options] PATH Options: -portable # -host <host:port> -db <name> # 从备份数据的哪个库恢复数据Name of database to be restored from the backup -newdb <name> # 数据恢复到新库名称,若没有指定，选择-db <name>的名称。newdb必须不存在，恢复时会自动创建 -rp <name> # 从备份数据的哪个rp恢复数据，指定了-rp，必须指定-db -newrp <name> #恢复数据新的rp名称，newrp必须存在。指定了-rp，未指定-newrp则使用-rp -shard <id> # 需要恢复的shard，如果指定了'-db <db_name>' and '-rp <rp_name>'，必须-shard<id> PATH #备份数据文件list
4.第二种导入方式：
删除influxdb数据库存储得元数据文件，将influxdb得数据库元文件目录指定为备份得目录，然后再重启influxdb数据库即可完成导入
influxd restore -metadir <path-to-meta-or-data-directory> <path-to-backup>
从/var/lib/influxdb/ 目录下删除meta目录，即 rm -rf /var/lib/influxdb/meta，然后重启influxdb，service influxdb restart。
