influxd backup <path-to-backup>

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.

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。

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.

Usage: influxd restore -portable [options] PATH
Options:
    -portable #

    -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>
