Azure Database for PostgresSQL with private endpoint and backups with Backup Vault
I am trying to set backups with Backup Vault on Azure Database for PostgresSQL which is using Private Endpoint, I have set everything with Terraform following this link. When I did on demand backup it failed. Then I add backup manually from the portal but it failed with the following error: [see screenshot]
I was looking in the documentation but didn't find anything on Backup vault using private endpoint.
But I found this link but it didn't help because the Backup vault still wasn't able to do the backup.
Any Ideas how shall I fix this?
How would I perform backup with Backup Vault while having Azure DB for Pg with private endpoint?
