<p>
Adds an attribute and values to, or removes an attribute and values from, a manual DB snapshot.
</p>
<p>
To share a manual DB snapshot with other Amazon Web Services accounts, specify <code>restore</code> as the
<code>AttributeName</code> and use the <code>ValuesToAdd</code> parameter to add a list of IDs of the Amazon Web
Services accounts that are authorized to restore the manual DB snapshot. Uses the value <code>all</code> to make
the manual DB snapshot public, which means it can be copied or restored by all Amazon Web Services accounts.
</p>
<note>
<p>
Don't add the <code>all</code> value for any manual DB snapshots that contain private information that you don't
want available to all Amazon Web Services accounts.
</p>
</note>
<p>
If the manual DB snapshot is encrypted, it can be shared, but only by specifying a list of authorized Amazon Web
Services account IDs for the <code>ValuesToAdd</code> parameter. You can't use <code>all</code> as a value for
that parameter in this case.
</p>
<p>
To view which Amazon Web Services accounts have access to copy or restore a manual DB snapshot, or whether a
manual DB snapshot public or private, use the <a>DescribeDBSnapshotAttributes</a> API operation. The accounts are
returned as values for the <code>restore</code> attribute.
