Failed to use an existing s3 bucket for backup

[zenhao]

I get this error message when I am trying to use an existing bucket with strata.

"Your previous request to create the named bucket succeeded and you already own it."
I think this is caused by BucketAlreadyOwnedByYou error. (more)

Is there a flag I can use to avoid this behavior: always try to create a new bucket?

// New creates a new S3.
func New(auth aws.Auth, region aws.Region) *S3 {
	return &S3{auth, region, 0, 0, aws.V2Signature, 0}
}

// Bucket returns a Bucket with the given name.
func (s3 *S3) Bucket(name string) *Bucket {
	if s3.Region.S3BucketEndpoint != "" || s3.Region.S3LowercaseBucket {
		name = strings.ToLower(name)
	}
	return &Bucket{s3, name}
}

Seems like New will always create a bucket.
Also can we support aws.V4Signature as well somehow?

Thanks

I resolved this by providing aws region.
Is there a way to support aws.V4Signature? some EU regions only support v4.
