DVDs can also fail without warning.

A DVD burner is pretty cheap, and I'd say worth getting if your computer is a desktop, especially if it currently lacks even a DVD reader.

Um, how is that ?

I'd think they can fail if you drop them, or smash them with something, yes, but without warning ? How is that ?

How do you know it's safe to delete old backups?

I don't know exactly but they do and not rarely enough. Sometimes root-like patterns can be seen reaching from the outer edge, between the see-through and shiny parts. Oxidation? Something alive? Sometimes they look perfect but cannot be read in their entirety.

Must be disks that are not stored properly. I have disks that are quite old, and they read just fine. Of course, it also depends on media quality. A lot of factors go into it, but overall I think DVDs are the best backup medium for regular users. Tapes are an option, but they're harder to find and are susceptible to magnets.

Are DVDs not CDs with a larger capacity? Do they use something different from and superior to this crystalline matrix thing I'm that told CDs use?

DVDs are similar to CDs. A factor that may make DVDs more long-lived is that in a CD the data layer is right under the label (I've lost commercial disks to label-side damage), while in a DVD the data layer is in the middle with polycarbonate both sides.

You can use CDs too, if you have little stuff to backup.
