There may come a time when you will want to have a backup file of your users' list. It is very easy to do so:
1 When in admin mode click on the Users -> All users:
2 At the top bar hover over Export users report and select the type of file you would like to download your backup users' list (xls or CSV file formats). You can also select specific filters and export the data, e.g. a specific course/date/Users.
