One backup solution that 'just works'. Maybe the technology doesn't yet exist or is not just being applied correctly. I must be fast, easily expandable, easily accessed, secure, future proof. Also a storage company which follows 'moores law', ie like a dropbox that automatically expands your storage size as time goes by.
