How do I connect an Amazon S3 bucket to Storage Studio?
Short answer: In Cloud Accounts, choose Add Account, then Bucket Storage, pick Amazon Web Services, and enter a nickname, Access Key ID, Secret Access Key, Region and Bucket. Leave the endpoint blank, save, then click Test connection.
Open Cloud Accounts → Add Account → Bucket Storage, choose the Amazon Web Services provider, then fill in a nickname, your Access Key ID, Secret Access Key, Region and Bucket. Leave the endpoint empty, click Save account, then Test connection.
You do the Amazon parts in Amazon's own console first: create the bucket (note its region), and create a separate user with access to just that bucket, then copy its access key and secret. Storage Studio only needs the finished keys, region and bucket name.
