听起来你即将做的事情，将整个 XYZ 项目文件夹从“我的 Paratext 项目”文件夹复制到另一个位置可能就足够了。这样，如果出了问题，你只需删除该项目，然后将该文件夹复制回原处即可。这是“备份”最简单的方法，尤其是在准备进行一次你不确定结果的一次性更改时。
与其使用“在项目历史中标记点”，我建议你直接执行 Send/Receive。该过程也会标记一个点，但优点是备份稍微更稳健一些——如果你做了灾难性的操作覆盖了本地机器上的历史数据，该备份仍然在云端。这个过程比第一段中建议的简单复制文件夹要好，但恢复起来也稍微复杂一点。
知道很难做出糟糕到无法恢复项目旧副本的更改，这让人放心。我会说，你 几乎不可能将数据损坏到那种程度，但对于拥有备份注册表访问权限的人来说并非不可能。

如果你使用复制文件夹的方法，实际上不需要任何权限。
如果你试图恢复历史中的某个旧点，你可能需要管理员 权限（我一时想不起来）。如果你犯了如此大的错误以至于无法修复，你可能需要向有服务器访问权限的人寻求帮助。

这取决于你做了什么样的更改。但根据你的操作，在对该项目进行后续编辑之前，你需要仔细测试。删除错误并回到几小时前保存的状态非常容易。但在一个月的工作后，意识到某些数据损坏了，而同时你也做了许多正确的更改，这非常困难。
For what it sounds like you're about to do, copying the entire XYZ project folder out of your My Paratext Projects folder into another location is probably sufficient. Then, if something goes wrong, you can simply delete the project and then copy that folder back into its original place. That's by far the easiest way of "backing up", particularly in preparation for a one-time change that you're unsure of.
Rather that "Mark Point in Project History", I would recommend simply doing a Send/Receive. That process also marks a point, but has the advantage of being a slightly more robust backup--if you do something catastrophic to overwrite the history data on your local machine, that backup would still be in the cloud. This process is better than just copying the folder out like it suggested in my first paragraph, but it's also slightly more complicated to restore things.
It is reassuring to know that it is extremely difficult to make a change that is so bad that someone can't restore an old copy of your project. I'd say it's almost impossible for you to corrupt data such an extreme, but not impossible for someone with access to the backup registry.

If you use the copy-folder method, you don't really need any privileges at all.
If you are trying to restore an old point in history, you may need administrator privileges (I can't remember off the top of my head). And if you made such a huge mistake that you can't fix it, you might need to ask for help from someone with access to the server.

That kind of depends on what change you made. But depending on what you're doing, you'll want to test this carefully before doing future editing on the project. It's extremely easy to delete a mistake and go back to a saved state a few hours ago. It's extremely difficult to realize after a month of work that some data is broken, but you've also made lots of correct changes in the meantime.
