Not in this version yet, but in a future version, while the text of the Bible is being edited, Bibledit will make backup copies of it at regular times.
It is very important to make regular backup copies of your work, in particular of the data directory of Bibledit.
A good reason to store the data of Bibledit elsewhere, e.g. on a server, can be for backup purposes. See the Questions section for how to move it.
