Not sure I understand what you are tryng to accomplish but here is my interpretation:
You are running two file backup jobs - One to the NAS and another to AWS, but these jobs backup data from two separate clients/companies.
You want to wind up with two jobs for each company - one to NAS and the other to AWS - each containing only one companies files/folders..
The easiest way to accomplish this is to clone the existing jobs and then go into the "What to backup" and select the appropriate files/folders for each one.
The data that is already on the NAS/AWS doesn't change and no re-uploading is involved.
If this is not what you are looking to do please elaborate.

Sorry but it is not my primary language. The backup source is always the same and consists of multiple folders into 1 backup job. I want to make 2 backup jobs and move backed up data from the existing into the new job. If possible i want also to move the backup data into another datastore in cloudberry

So how Cloudberry keeps track of different versions? It looks like CBB just puts them into different folders. May i move complete subfolders from one backup set into another one which is stored on a different backup storage?

Is this possible? Unfortunatley Cloudberry also doesnt give any technical support

I got the answer, its not possible to split the data
