I just did my first archive. I split the archives into 4482MB files
(which is the capacity of a DVD in MB from what I can figure out.) I
also set the parity to 5%. As you can see below 7 archive files were
created and 8 parity files.

The documentation is a bit thin in the archive section so I have a few
questions.
1. What is parity? What are the parity files for and How do you use
them with the archives?
2. I chose bZ2 for my backup, to minimize disk usage. The archiving
took 680mins to backup. If I chose gzip instead how much difference
would there be? How much bigger would the archive be and how much
faster would it be. I am planning to do quite a few backups to DVD in
future, so I thought now would be the time to ask.

ls -alh of the DVD backup directory:
