This seems like a completely different topic than the thread subject, and you likely should start a new thread.

There are any number of ways to save your data. I prefer sending it across a network by FTP. How you do it depends on your situation, the amount of data to be saved, your available hardware, and even the value of the data to you. Some other options include USB flash devices, external hard drives, even adding another internal drive, as well as burning one or more discs. But burning discs requires either multiple drives or enough memory to load Knoppix completely into RAM. An alternative way to burn to disc if you don't have the memory or multiple drives would be to use s smaller distro such as Puppy Linux or DSL.
