Those are good examples. For instance I use SkyDrive and DropBox but not for too sensitive backup (and they do offer extra storage and encourage me to post ALL my files in case of disk failure...).
I do it for general sharing purposes because it's way easier than trying to upload in many different places with speed limits or size limits (or email upload limits - spam-regarded attachments) and remembering a bunch of different links for example.
