Choose between Backup and Recovery providers at Domain level allowing option for CS customers between Adhoc & SLA Backups

[notdrowningworking]

Currently the B&R framework is configured and set at the Zone level, and you can only have 1 backup provider per zone.

This seems somewhat restrictive. Wouldn't it be great to give a customer the choice between a free B&R solution and one that is fully managed by the CSP and is hands off?

Would it be possible to request a feature enhancement to add the zone config setting backup.framework.provider.plugin to the Domain also?

Having the provider configured in the Zone could be the default for any domain that does not have the provider configured. If a customer top-level Domain contains a different provider this could take precedence. (Obviously the Zone would need to have configuration settings to support 2 B&R providers).

This would allow the CSP to offer 2 Backup options to tenants.

I imagine there may be challenges running potentially 2 backup providers on the same host and cluster in the same zone. However no single customer tenant could ever have 2 different B&R providers. A customer's top level domain would contain the backup.framework.provider.plugin if it is different to the Zone setting then this B&R framework is used, any subdomains would not be allowed to have this setting configured and would inherit the domain above.

The root domain would inherit the Zone backup.framework.provider.plugin.

Another option might be to have another Zone setting that allows more than 1 B&R provider to be configured, such as backup.framework.provider.multiplugin that allows only max 2 providers, eg. veeam-kvm, kboss or veeam-kvm, nas or networker, nas. Then the Domain setting backup.framework.provider.plugin must only contain a plugin from the Zone backup.framework.provider.multiplugin.

Use Case
At this stage we are planning to implement Veeam KVM, which will be an SLA fully managed backup solution for all our CloudStack customer tenants. However we have customers who would like the choice of opting for a simpler and cheaper integrated B&R (either the NAS or KBOSS) which they can control and manage themselves instead of paying a higher premium for us to manage it for them, which is less flexible. In our case we could offer NAS or KBOSS as the Adhoc user managed B&R that has no license fees.
