With VERSION HISTORY in GOOGLE DOCS you'll never have to worry if you delete something. You can restore any version or make a copy of any version!
When you click on File and hover over Version History, you
can select Name Current Version. Naming the version makes it easier to find and
select it when you are scrolling through the Version History. If you select See
Version History and click on an entry from Version History, when you click on
the 3 dots, you can also Name the Version and leave it in the Version History.
Finally, another great option when you click on the 3 dots is the ability to
Make a Copy. This is really helpful because when you Restore a Version, you
lose the current version. With Make a Copy you can keep the current version and
still have a copy of a previous version.
