<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
using 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. Setting this affects can
affect both billing and legal concerns, so you are encouraged to consult
Amazon's documentation for details.

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

If a location constraint is set, the bucket name will need to consist only of
lower-case letters, numbers, dashes, and dots.
