This is clearly a problem for the reputation of dropbox.
On their website they market the service as:
"Even if your phone goes for a swim, your stuff is always safe in Dropbox and can be restored in a snap."
With this message in mind, and a valuation of roughly >>10$ BILLION<<.
I think, you can have very very high expectations regarding the data retention of their service.
Also, the whole point of using a service like dropbox is to remove friction/time investment regarding the standard backup/sync tasks.
If you suggests to handle multiple harddisk backups locally+offsite, that is fine except that not everyone wants this kind of time investment and cost associated with a do-it-yourself backup service and rather depend on a service provider that they can trust.
