I would like to know what forms of backup people have found most effective as I have decided it is time to invest in something to do this. I have a 20gb hard drive but am presently only using about 2gb. I want to be able to recover from a total disaster but also want to be able to get back files or groups of files in case of a partial corruption or accidental deletion. The options I know about are: cdrom, tape, another hard disk, or zip drive. Thanks. -- Cheryl
