If you don't want to download Adobe ePUB versions of your Kobo books, as backups, and you are looking for a way to backup kepub versions, in case Kobo books goes away, you can backup those books on your computer.
The kobobooks that
are currently in the library of the desktop software are stored in a folder with an address like this: C:\Users\YourName\AppData\Local\Kobo\Kobo Desktop Edition\kepub . This is the Windows 7 path, YMMV with other OS.
The problem is that once your book is no longer in the desktop library, it is no longer in that directory on your computer. If you want to backup a copy of any book you have ever purchased/downloaded from kobobooks.com, then you need to run a bit of software that will take any book that ever lands in the directory and back it up somewhere else. The trick is to set-up a one way sync--so that books that go into the kepub directory are copied into that one, but unaffected by deletions from your original kepub directory.I use a free program called Allway Sync. I have set it up so that it automatically copies files/books from C:\Users\Vicki\MyName\Local\Kobo\Kobo Desktop Edition\kepub into a file in MyDocuments I call kobo backup. Books come in, but they never leave
