<p class="msonormal" id="obs_04_0082__p19640290">Users can determine whether to copy the metadata of the source object to the target object (by default) or replace the metadata of the target object with the metadata contained in the request. The ACL of the source object is not copied to the target object. By default, the ACL of the target object is private. You can set an ACL for the target object by sending an API request.</p>
<p class="msonormal" id="obs_04_0082__p42544890">The request for copying an object needs to carry the information about the bucket and object to be copied in the header field. The message body cannot be carried.</p>
<p class="msonormal" id="obs_04_0082__p47359691">This operation supports server-side encryption.</p>
<p id="obs_04_0082__p9615112319534">An object copy can be up to 5 GB in size. If the source object size exceeds 5 GB, you can only <a href="obs_04_0100.html">copy part of the object</a>.</p>

<div class="section" id="obs_04_0082__section23584040"><h4 class="sectiontitle">Versioning</h4><p class="msonormal" id="obs_04_0082__p10189271">By default, <strong id="obs_04_0082__b48514746">x-obs-copy-source</strong> specifies the latest version of the source object. If the latest version of the source object has a deletion marker, the object is considered to have been deleted. You can add <strong id="obs_04_0082__b33979533">versionId</strong> to request header <strong id="obs_04_0082__b37380344">x-obs-copy-source</strong> to copy an object with the specified version ID.</p>
<p class="msonormal" id="obs_04_0082__p24594578">If a bucket has versioning enabled, the system automatically generates a unique version ID for the requested object in this bucket and returns the version ID in response header <strong id="obs_04_0082__b7909027">x-obs-version-id</strong>. If versioning is suspended for the bucket, the object version ID is <strong id="obs_04_0082__b6348185161214">null</strong>.</p>

After the copying is executed successfully, only new object_B can be downloaded because old object_B has been deleted. Therefore, before copying an object, ensure that there is no object with the same name as the object copy to prevent data from being deleted mistakenly. During the copying, object_A has no changes. </p>
</div></div>
<p class="cautiontext" id="obs_04_0082__p49467454">You cannot determine whether a request is executed successfully only using <strong id="obs_04_0082__b733137133204115">status_code</strong> in the header returned by HTTP. If 200 in <strong id="obs_04_0082__b1634619502204120">status_code</strong> is returned, the server has received the request and starts to process the request. The body in the response shows whether the copy succeeds. If the body contains ETag, the copy succeeds. Otherwise, the copy failed.</p>

<div class="section" id="obs_04_0082__section1475721115541"><h4 class="sectiontitle">WORM</h4><p id="obs_04_0082__p134973436414">If a bucket has WORM enabled, you can configure retention policies for objects in the bucket. You can specify the <strong id="obs_04_0082__b16286138101016">x-obs-object-lock-mode</strong> and <strong id="obs_04_0082__b142863861017">x-obs-object-lock-retain-until-date</strong> headers to configure a retention policy when you copy an object. If you do not specify these two headers but have configured a default bucket-level WORM policy, this default policy automatically applies to the object newly copied. You can also configure or update a WORM retention policy after an object is copied to the bucket.</p>

After the copy is complete, WORM retention changes made on the source object does not affect the object copy.</p>
