Hi @simonsimon1129,
I don’t think that this is possible - at least it is not as easy as you might think.
Veeam cloud backup appliances (such as Veeam Backup for AWS or Veeam Backup for Azure) always use object storage repisitories in the first backup tier, so you cannot directly backup to anything else:
Step 3. Configure Repository Settings - Veeam Backup for AWS Guide
Then you are able to create a backup copy job but in this case you have to define a breakout to your on-prem environment, this should also be based on the S3 protocol (object storage). An on-prem VBR (Veeam Backup & Replication) then could be able to restore the data using instant recovery but this doesn’t seem to work with Proxmox yet:
Instant Recovery - Veeam Backup for AWS Guide
Keep in mind that cloud usually work with object storage architectures on that level and you local hard drives are block storage architectures.
What you need in general to work with data between clouds and on-prems in my opinion:
- Veeam Backup for AWS (you will at least pay the resource costs of AWS)
- Veeam Backup & Replication on-prem
- on-prem object storage repository (this would be you copy repo)
- on-prem Hypervisor
I’m not sure if Proxmox is supported for this yet because the documentation (latest link above) is from 2023 as it seems but worth a try.
I also don’t think that this scenario is possible with no costs at all and in this kind of complex use case I always recommend purchasing licenses for the Veeam products since they provide Veeam support in case needed.
Hope that helps, maybe there are other feedbacks or ideas.
Best
Lukas
