Backup Copies

Because all coded datasets are directly processed (no copies are generated at all), a program interrupt in the coding phase can irretrievably destroy (!) one or more datasets, i.e. you absolutely have to make backup copies e.g. on other storage media (!). In success these copies can be replaced by the encoding results to get protection against troubles during decoding.

To rule out an unintentional mistake regarding this, the program only starts if you have explicitly confirmed that you have made backup copies !
