I understand that grouping similar VM's into fewer jobs provides greater deduplication efficiency than separating such VM's into individual jobs.
However, separating VM's into individual jobs provides greater flexibility: Each VM's job can be configured with unique restore points, backup modes, and backup schedules.
Also, if I want to run a backup for just one VM, I can do this more easily when each VM has its own job. If many VM's are group into just one job, and I need to run a backup for a specific VM in that job during the day (such as in the event of an emergency), I would have to run the entire job backing up all of the job's VM's just to get the one backup for the VM that I need.
If I understand this Veeam B&R design correctly, than clearly Veeam B&R creates a tug-of-war between grouping VM's into a few or just one backup job for greater deduplication efficiency and easier job management versus separating VM's into numerous jobs for greater flexibility of job configuration.
This seems to be a design issue...or, a product limitation. The key problem is the lack of a "global," folder-based or volume-based deduplication engine in Veeam B&R. If we could simply set Veeam B&R to deduplicate all jobs stored in XYZ folder on the server...problem solved.
I would appreciate any comments from Veeam on this. Maybe I'm missing something important here?
(I have already read this forum's FAQs and other posts on this subject).

If we simply created a "folder" where everything was deduplicated, then the backup files would no longer be self contained entities. It's also much more difficult to scale this pool from a performance perspective. You'd likely end up with multiple dedupe pools across multiple disks, and obviously that would still lead to less-than-optimal deduplication.
Note that I'm not saying that having a pool and deduplicating across them is not a good idea, simply that it is, as of today, not a part of the design of the product. You can do this today with a software deduplication option or a hardware dedupe appliance.
