Hi @a8ree1 Sorry for the delay in response to your query.
Since Azure Backup uses the Recovery Services Vault (RSV), which is scoped to a subscription, cross-subscription backup and restore is not currently supported.
Not being a Data SME, could you use the native SQL backup functionality, write that file to a drive/folder, and perform a file-level backup. Then, with the file recovery script process, mount that recovery point to the non-Prod VM, to obtain the .bak file.
Or, another option could be to use Azure Files/Azure File Sync as a file server, which may allow access to the same content across Prod/Non-Prod.
