SharePoint中的备份层次结构使用户能够查看和恢复意外删除的版本。因此，在这篇文章中，我们将看到在SharePoint 库^{(SharePoint Library)}中恢复旧版本的方法。

Office.com 上的博客文章说：

SharePoint doesn’t remove the earlier version you just restored, it creates a copy and makes it the latest version. If your SharePoint lists or libraries are set to track versions, you can restore a previous version of a list item or file.

在SharePoint 库^{(SharePoint Library)}中恢复已删除的文档版本

如果SharePoint 库^{(SharePoint Library)}或列表^(List)中的文档被意外删除，则可以撤消操作。但是，要使该过程正常工作，您需要将SharePoint列表或库设置为跟踪版本。只有完成此操作后，您才能恢复列表项或文件的先前版本。要在SharePoint^(SharePoint)中恢复文件的早期版本，意外删除，

1. 访问 SharePoint 库
2. 转到版本历史记录部分
3. 恢复所需的版本

^{(Version History)}在SharePoint^(SharePoint)中默认打开版本历史记录，但如果您没有看到版本历史记录^{(Version History)}命令，则版本历史记录可能已关闭。

如果您的列表或库的名称不可见，请单击“站点内容^{(Site contents)}”或“查看所有站点内容^{(View All Site Content)}”，然后选择您的列表或库的名称。

2]转到版本历史记录部分

现在，右键单击项目或文档名称和日期之间的空格，然后从菜单中选择“版本历史^{(Version History)}”选项。您可能需要滚动菜单才能查看版本历史记录^{(Version History)}。在那里，您将看到如上图所示的文件版本列表。

3]恢复所需的版本

在“版本历史^{(Version History)}”对话框中，将鼠标光标悬停在要恢复的版本上，然后单击其旁边的向下箭头以获取选项列表。

选择“恢复^(Restore)”选项。

当系统提示您确认用所选版本替换当前版本时，点击“确定”按钮。

请^(Please)注意，SharePoint不会删除您刚刚选择还原的早期版本。相反，它会创建一个副本并使其成为最新版本。

How to recover & restore deleted file in SharePoint

The backup hierarchy in SharePoint enables a user to νiew and restorе a version if it has been deletеd accidentаlly. So, in this post, we’ll see the method to recover an older version in SharePoint Library.

Says the blog post on Office.com:

SharePoint doesn’t remove the earlier version you just restored, it creates a copy and makes it the latest version. If your SharePoint lists or libraries are set to track versions, you can restore a previous version of a list item or file.

Restore deleted document version in SharePoint Library

If a document in SharePoint Library or List is deleted accidentally, the action can be reversed. However, for the process to work you’ll need to have your SharePoint lists or libraries set to track versions. Only when this is done, you can restore a previous version of a list item or file. To restore an earlier version of the file in SharePoint, deleted accidentally,

1. Access SharePoint Library
2. Go to Version History section
3. Restore the desired version

Version History is turned on by default in SharePoint, but if you don’t see the Version History command, version history may be turned off.

1] Access SharePoint Library

Go to the SharePoint Quick Launch bar and open the list or library.

If the name of your list or library is not visible, click ‘Site contents’ or ‘View All Site Content’, and then choose the name of your list or library.

2] Go to Version History section

Now, right-click on the space between the item or document name and date, and choose ‘Version History’ option from the menu. You might need to scroll the menu to see Version History. There, you’ll see a list of versions of the file as shown in the image above.

3] Restore the desired version

When in the ‘Version History’ dialog, hover your mouse cursor over the version you would like to restore and click the down arrow adjacent to it to get a list of options.

Choose ‘Restore’ option.

When prompted with a message to confirm the replacement of the current version with the one selected, hit the ‘Ok’ button.

Please note that SharePoint doesn’t remove the earlier version you have just chosen to restore. Instead, it creates a copy and makes it the latest version.
