Method: projects.databases.exportDocuments

Exports a copy of all or a subset of documents from Google Cloud Firestore to another storage system, such as Google Cloud Storage. Recent updates to documents may not be reflected in the export. The export occurs in the background and its progress can be monitored and managed via the Operation resource that is created. The output of an export may only be used once the associated operation is done. If an export operation is cancelled before completion it may leave partial data behind in Google Cloud Storage.

HTTP request

POST https://firestore.googleapis.com/v1beta2/{name=projects/*/databases/*}:exportDocuments

The URL uses gRPC Transcoding syntax.

Path parameters

Database to export. Should be of the form: projects/{projectId}/databases/{databaseId}.

The request body contains data with the following structure:

JSON representation 
{
  "collectionIds": [
    string
  ],
  "outputUriPrefix": string
}
Fields

string

Which collection ids to export. Unspecified means all collections.
outputUriPrefix

string

The output URI. Currently only supports Google Cloud Storage URIs of the form: gs://BUCKET_NAME[/NAMESPACE_PATH], where BUCKET_NAME is the name of the Google Cloud Storage bucket and NAMESPACE_PATH is an optional Google Cloud Storage namespace path. When choosing a name, be sure to consider Google Cloud Storage naming guidelines: https://cloud.google.com/storage/docs/naming. If the URI is a bucket (without a namespace path), a prefix will be generated based on the start time.
