Investment? More like insurance.
If my house were to be flooded or burn down and we loose everything in it (images, documents, program code,...) that is local to my PC/office, the cloud is my disaster recovery archive. It is not working storage...
The real question here is: "How much are your images worth to you? To your family?"
You insure your car against damage and theft. (Most states require it in order to register the vehicle).
You insure your home against damage and theft. (Most mortgage companies require it).
You insure your health against catastrophic diseases or accidents.
All those things have value to you. What about your photos?
I am definitely not of the persuasion that my photos have any monetary value. There are some, however, that have value to me and/or my family. I want to protect them. I spend a bit over $100/year for software to polish my photos. That amount is a small price to pay for a hobby. I can certainly add another $100 or thereabouts to protect my images to preserve them for the future. Financially I am able to support that kind of expenditure. I recognize that I am lucky and the expenditure of that money will not make me miss any meals, no matter how much it might benefit me to miss a meal now and then. Others may not be so lucky.
The decision is up to you.
And to repeat what has been said about backup many times, many places:
Backup (archive) requires (at least) three things: Duplication, Distribution, and Maintenance.
You need several copies of your backup (Duplication). That ensures that if one backup medium fails there is another that can take up the slack.
You need the backup to be in several places (Distribution). That way if a meteor makes a crater where your house was, there is a backup somewhere else that you can use.
You need to keep up with technology. Backup media do not last forever. The Mean Time Between Failures of your storage medium is important, so the medium has to be replaced occasionally to avoid that problem.
Cloud storage addresses all three of those things.
Cloud storage has the disadvantage that it is bandwidth limited. It will take a long time to restore ALL your files.
Local storage has the advantage that it has a high bandwidth available. Much quicker to restore your files from a local disk.
Local storage has the disadvantage that YOU have to do the maintenance. Cloud storage takes care of that. Maintenance is done by professionals.
Local storage is your prime backup. Cloud storage is your backup backup.
And on the subject of media, DVDs are deprecated as a backup medium. Their lifetime may or may not be long. They are inconsistent there.
