This page describes various Cloud Storage tools that you can use to work with data stored in other cloud providers.
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). To use these tools
and libraries, change the request endpoint that the tool or library uses to
the Cloud Storage URI
https://storage.googleapis.com, and configure
the tool or library to use your Cloud Storage HMAC keys. For
detailed instructions on migrating from Amazon S3 to Cloud Storage, see
Migrating from Amazon S3 to Cloud Storage.
V4 signing process
When using the V4 signing process to create signed requests for Cloud Storage resources, you can perform the signing with an RSA signature or sign using your Amazon S3 workflow and HMAC credentials.
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 lists the objects in the Amazon S3 bucket
gsutil ls s3://example-bucket
The following command synchronizes 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.
Amazon S3 bucket names containing dots
If you attempt to use gsutil to access a Amazon S3 bucket that contains a dot
in its name, you might receive an
invalid certificate error. This is because
Amazon S3 does not support virtual-hosted bucket URLs with dots in their
name. You can configure gsutil to attempt to use path-style bucket URLs when
working with Amazon S3 resources by adding the following entry to your
.boto configuration file for gsutil:
[s3] calling_format = boto.s3.connection.OrdinaryCallingFormat
Using the Storage Transfer Service
Storage Transfer Service enables you to easily import large amounts of online data into Cloud Storage from Amazon S3 buckets, Microsoft Azure Storage containers, and general HTTP/HTTPS locations. Storage Transfer Service can be used to schedule recurring transfers, delete source objects, and select which objects are transferred.
