That burning split archives is a PITA is the other good reason not to
use DVDs ;D.
External HDDs are the better medias for backups at home. DVDRAM
theoretically would be ok too.
CDs, DVDs and USB sticks etc. aren't safe medias. I guess we all
experienced that data is less safe on those medias.
I don't know what is used for what kind of professional backup. Since
I'm a musician and I used DAT for mastering audio productions, I
wouldn't use that kind of tape to backup computer data. As fat as know
those tapes are often used for backups, they aren't called DAT, but the
machines and tapes are the same. Sometimes I used data tapes for audio
recordings.
I experienced floppy disk as very safe, I still own some as old as a
T-Rex, even high density disks that were used with averaged double
density drives are still ok.
