Using the XML API
The Cloud Storage XML API is interoperable with some cloud storage tools and libraries that work with services such as Amazon Simple Storage Service (Amazon S3) and Eucalyptus Systems, Inc. To use these tools and libraries, change the request endpoint (URI) that the tool or library uses so it points to the Cloud Storage URI (https://storage.googleapis.com), and configure the tool or library to use your Cloud Storage developer keys. For detailed instructions on migrating from Amazon S3 to Cloud Storage, see Migrating from Amazon S3 to Cloud Storage.
Using the gsutil command line
The gsutil tool lets you access Cloud Storage from the command line. It
can also be used to access and work with other cloud storage services that use
HMAC authentication, like Amazon S3. For example, after you add your
Amazon S3 credentials to the .boto configuration file for gsutil, you can start using
gsutil to manage objects in your Amazon S3 buckets. The following command will
list the objects in the Amazon S3 bucket example-bucket:
gsutil ls s3://example-bucket
The following command will synchronize data between an Amazon S3 bucket and a Cloud Storage bucket:
gsutil rsync -d -r s3://my-aws-bucket gs://example-bucket
For more information, including details on how to set up gsutil to optimize this synchronization, see the gsutil rsync documentation.
Using the Storage Transfer Service
Storage Transfer Service enables you to import large amounts of online data into Cloud Storage from Amazon Simple Storage Service (Amazon S3) buckets and general HTTP/HTTPS locations. Storage Transfer Service can optionally schedule transfers, delete source objects, and select which objects are transferred.
