My current thinking is to skip the backups. Get both a SCSI and an IDE drive, use the SCSI and back up the first onto the latter. Then use CDs if I have anything that I really want to keep.
I don't keep anything on my home computer that would really kill me to lose. And if there was something that I created, then it won't be large. (Takes a whole lotta text to go past 100 MB. I am not running a server...) Beyond that what do I gain with full system backups? The ability to recover my system as is if I buy another just like the old. But I don't have that other machine to recover onto. And I probably wouldn't mind the opportunity to install a better system.
If I was doing anything that I cared about (my own email, archives, a code repository, finances) then I would have regular automatic backups. But I am not. Someone could toast my computer right now and my lack of a backup would not bother me. I don't see that changing.
Any thoughts on other consumer items? Should I bother with a DVD drive? (How accessible are admittedly illegal programs to let me play them on my nicer monitor?) How well do things like scanners, digital cameras, etc work with Linux?
Cheers,
Ben
