Cloud Storage is compatible with some other object storage platforms so you can seamlessly integrate data from different sources. This page describes Cloud Storage tools you can use to manage your cross-platform object data.
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 with Cloud Storage, change the request endpoint
that the tool or library uses to the Cloud Storage URI
https://storage.googleapis.com, and then configure
the tool or library to use your Cloud Storage HMAC keys. See
Migrating from Amazon Simple Storage Service (Amazon S3) for detailed instructions on getting started.
V4 signing process
The V4 signing process allows you to create signed requests for Cloud Storage. You can perform the signing process by using an RSA signature or 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 also lets you access and work with other cloud storage services that use HMAC authentication, like Amazon S3. After you add your Amazon S3 credentials to ~/.aws/credentials, you can start using gsutil to manage objects in your Amazon S3 buckets. For example:
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.
Invalid certificate from Amazon S3 bucket names containing dots
If you attempt to use gsutil to access an 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. When working with Amazon S3 resources, you can configure gsutil
to attempt to use path-style bucket URLs 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.
