* `/api/v1/export/native` for exporting data in native binary format. This is the most efficient format for data export.
See [these docs](#how-to-export-data-in-native-format) for details.

### How to export data in native format
Send a request to `http://<victoriametrics-addr>:8428/api/v1/export/native?match[]=<timeseries_selector_for_export>`,
where `<timeseries_selector_for_export>` may contain any [time series selector](https://prometheus.io/docs/prometheus/latest/querying/basics/#time-series-selectors)
for metrics to export. Use `{__name__=~".*"}` selector for fetching all the time series.
On large databases you may experience problems with limit on unique timeseries (default value is 300000). In this case you need to adjust `-search.maxUniqueTimeseries` parameter:
```bash
# count unique timeseries in database
wget -O- -q 'http://your_victoriametrics_instance:8428/api/v1/series/count' | jq '.data[0]'
# relaunch victoriametrics with search.maxUniqueTimeseries more than value from previous command
```
Optional `start` and `end` args may be added to the request in order to limit the time frame for the exported data. These args may contain either
unix timestamp in seconds or [RFC3339](https://www.ietf.org/rfc/rfc3339.txt) values.
The exported data can be imported to VictoriaMetrics via [/api/v1/import/native](#how-to-import-data-in-native-format).
The native export format may change in incompatible way between VictoriaMetrics releases, so the data exported from the release X
can fail to be imported into VictoriaMetrics release Y.

### How to import data in native format
The specification of VictoriaMetrics' native format may yet change and is not formally documented yet. So currently we do not recommend that external clients attempt to pack their own metrics in native format file.
If you have a native format file obtained via [/api/v1/export/native](#how-to-export-data-in-native-format) however this is the most efficient protocol for importing data in.
```bash
# Export the data from <source-victoriametrics>:

# Import the data to <destination-victoriametrics>:
curl -X POST http://destination-victoriametrics:8428/api/v1/import/native -T exported_data.bin

Pass `Content-Encoding: gzip` HTTP request header to `/api/v1/import/native` for importing gzipped data:
```bash
# Export gzipped data from <source-victoriametrics>:
curl -H 'Accept-Encoding: gzip' http://source-victoriametrics:8428/api/v1/export/native -d 'match={__name__!=""}' > exported_data.bin.gz
# Import gzipped data to <destination-victoriametrics>:
curl -X POST -H 'Content-Encoding: gzip' http://destination-victoriametrics:8428/api/v1/import/native -T exported_data.bin.gz
```
Extra labels may be added to all the imported time series by passing `extra_label=name=value` query args.
For example, `/api/v1/import/native?extra_label=foo=bar` would add `"foo":"bar"` label to all the imported time series.

It loads the whole JSON line in memory, then parses it and then saves the parsed samples into persistent storage. This means that VictoriaMetrics can occupy big amounts of RAM when importing too long JSON lines. The solution is to split too long JSON lines into smaller lines. It is OK if samples for a single time series are split among multiple JSON lines.
### How to import data in native format
The specification of VictoriaMetrics' native format may yet change and is not formally documented yet. So currently we do not recommend that external clients attempt to pack their own metrics in native format file.
If you have a native format file obtained via [/api/v1/export/native](#how-to-export-data-in-native-format) however this is the most efficient protocol for importing data in.
```bash
# Export the data from <source-victoriametrics>:
curl http://source-victoriametrics:8428/api/v1/export/native -d 'match={__name__!=""}' > exported_data.bin
# Import the data to <destination-victoriametrics>:
curl -X POST http://destination-victoriametrics:8428/api/v1/import/native -T exported_data.bin
```
Extra labels may be added to all the imported time series by passing `extra_label=name=value` query args.
For example, `/api/v1/import/native?extra_label=foo=bar` would add `"foo":"bar"` label to all the imported time series.
Note that it could be required to flush response cache after importing historical data. See [these docs](#backfilling) for detail.

Pass `Content-Encoding: gzip` HTTP request header to `/api/v1/import/prometheus` for importing gzipped data:
```bash
# Import gzipped data to <destination-victoriametrics>:
curl -X POST -H 'Content-Encoding: gzip' http://destination-victoriametrics:8428/api/v1/import/prometheus -T prometheus_data.gz
