Azure Blob and Object Storage

[osonder]

In my Veeam Backup for Office365, I have added Azure Blob under Object Storage Repositories.
I guess I have to add this storage to Backup Repositories as well, but how to do this?
When trying to add new repositories, I only see my local disks, and when I try to set up a new backup job, I only see my default Backup Repositoires (local disks)

When you add a new backup repository, you will be able to extend it to the object storage. For more information, please consult the information in the user guide.

Thanks for your fast reply. Is it not possible to just use my Object Storage (Azure Blob)?
If I edit my default repositories, Im not able to select this options to extend

Added a new Repositories and was now able to choose the Object Storage to extend. But I dont want to use local disk, because I dont have local space avaible

The cache is just 1-2% of the backed-up data size, and it's a must to have when backing up to object storage.

OK. Thx. The local disk is only my C: disk, so maybee I should add an additional disk, so C: is leaved alone
