<para>
Amanda automatically creates a bucket when writing, if the bucket doesn't
already exist. At that time, it specifies where Amazon should store the data
based on the S3_BUCKET_LOCATION property. Currently, there are two valid settings:
"*" (any location, probably US) and "EU" (Europe). If this property is not set,
Amazon's default value of "*" is used. The bucket location has both billing and
legal concerns, so you are encouraged to consult Amazon's documentation for details.
</para>

<para>
Amazon does not permit changes to bucket locations, so this is a permanent
specification. If the bucket already exists and the property is set,
then Amanda checks the property against the location of the bucket, and
produces an error if they do not match.

<note><para>
If a location constraint is set, the bucket name must consist only of
lower-case letters, numbers, dashes, and dots.
