CDs are for music and DVDs are for films. Data which must be moved goes over the internet, on cloud storage, or on removable SSDs.
Writable CDs don't seem to be a good proposition as the media seem to be rather fragile, being particularly vulnerable to temerature cycling. A week in the car seems to be pretty good at turning an audio disk that plays flawlessly into one where the player can't even read the table of contents. The drives to write the media also seem to wear out pretty quickly.
I haven't had a chance to try writable DVD for data backups - the capacity is not particularly high and I'd be nervous of the same problem as with CD.
If you have the network bandwidth to do it, backing up to a hard disk storage in a remote location seems good both in convenience and in the probable reliability of the media.
