I would like to know which is the best way to create a backup and restore procedure in VB Code. What are the diferences between both tasks.

to use PKZIP and PKUNZIP utility compress decompress
if I use this utility in my programs do I have to pay some fee to the PKZIP creator company?.

OR

to use CopyFile Script procedure
With this procedure is posibly to create a serie of floppy disk from a database backup?

Thank for your cooperation
