根據您描述的情況，將整個 XYZ 專案資料夾從「My Paratext Projects」資料夾複製到其他位置，可能就足夠了。這樣，如果出錯，您只需刪除專案，然後將該資料夾複製回原處即可。這是「備份」最簡單的方法，特別是針對您不確定的一次性變更。
與其使用「在專案歷史中標記點」（Mark Point in Project History），我建議直接執行 Send/Receive。這個過程也會標記一個點，但優點是備份稍微更穩固——如果您對本機上的歷史數據做了災難性的覆蓋操作，該備份仍會保存在雲端。這個方法比第一段建議的僅複製資料夾要好，但恢復過程也稍微複雜一些。
令人安心的是，要做出壞到連舊版專案都無法恢復的變更，難度極高。我認為對於您 來說，幾乎不可能將數據損壞到那種程度，但對於擁有備份登錄檔（backup registry）存取權限的人來說，並非完全不可能。

如果您使用複製資料夾的方法，其實不需要任何特殊權限。
如果您嘗試恢復歷史上的某個舊點，可能需要管理員 權限（我一時想不起來）。如果您犯了大錯且無法修復，您可能需要向擁有伺服器存取權限的人尋求幫助。

這取決於您做了什麼變更。但根據您正在進行的工作，在專案上進行後續編輯之前，您會希望仔細測試。刪除錯誤並回到幾小時前保存的狀態非常容易。但經過一個月的努力工作後，才意識到部分數據損壞，而同時您也做了許多正確的變更，這就非常困難了。
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.
2 & 3
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.
