Your data is valuable. It is normally kept in the data directory.
If your data consists of a Bible that you translate, many years of work may have gone into it. It deserves maximum safety.
Bibledit offers a variety of mechanisms that deal with your data.
First there is the mechanism of "Backup". A backup makes an exact copy of your data and stores it onto some medium.
A "Restore" is the opposite of a backup. It takes that backup that was made earlier, and restores it into your data.
Then, there's "Import". It takes data in another format, and adds it to your own data.
Finally, there's "Export". It is the opposite of an import. It takes your data and exports it into another format.
