How to enable CDC for your database?
How to enable CDC for your database?
- By default CDC is enabled on your database. But for that, make sure you have the the sysadmin role. If not, you need to enable CDC manually by running the scripts on your database. For more information, see Enable CDC on database and tables.
Do we support Azure Arc?
Do we support Azure Arc?
- No.
I am an existing tenant for Azure VM. How do I onboard subscriptions for Azure SQL?
I am an existing tenant for Azure VM. How do I onboard subscriptions for Azure SQL?
- You can onboard Azure SQL subscriptions by updating your tenant registration permissions on Management Console. For more information, see Update Azure Tenant Registration.
Can I delete an Azure SQL subscription from the Enterprise Workloads Management Console?
Can I delete an Azure SQL subscription from the Enterprise Workloads Management Console?
- No, you cannot delete an Azure SQL subscription directly from the Enterprise Workloads Management Console. To delete a subscription, contact Support.
What is Druva Quantum Bridge?
What is Druva Quantum Bridge?
- For each backup or restore job request, Druva creates a virtual machine called Druva Quantum Bridge within the customer's Azure environment. This bridge facilitates communication between the SQL resource being protected and Druva Blob Storage. The naming convention for the Druva Quantum Bridge VM is:
DruvaQuantumBridge-<customerid>-<jobid>_<attempt_no>.
For example DruvaQuantumBridge-4354-1868_0
When should I use the Isolated Copy Protection backup method?
When should I use the Isolated Copy Protection backup method?
- Use Isolated Copy: For databases with Basic or Standard (S0, S1, and S2) service tiers, or if your database contains unsupported table types (like Graph or Memory-Optimized).
- Use CDC Backups: When you require more frequent recovery points and granular data capture for higher-tier databases (Standard S3 and above).
Does Isolated Copy protection work with Private Link?
Does Isolated Copy protection work with Private Link?
- Yes. Isolated Copy is fully compatible with Private Link environments. All data movement occurs over the Azure private backbone, ensuring traffic never traverses the public internet and remains compliant with strict network isolation policies.
Will Isolated Copy Protection slow down my production database?
Will Isolated Copy Protection slow down my production database?
- No. Because the backup is performed on a temporary, isolated copy, the primary backup processing is offloaded from your live production instance.
However, consider the following minor impacts:
Transaction Logs: There is a negligible, temporary load during the initial transaction log capture.
Elastic Pools: If your database is in an Elastic Pool, the temporary copy will consume pool resources (DTUs/vCores) for the duration of the backup. Ensure your pool has sufficient headroom to accommodate the copy.
Are there hidden Azure costs associated with the Isolated Copy Backup method?
Are there hidden Azure costs associated with the Isolated Copy Backup method?
- While Druva is egress-free, the Isolated Copy method utilizes temporary resources within your Azure subscription. You will see standard Azure consumption charges for:
Temporary Database Copy: Billed at your database's current tier rate for the duration of the backup.
Quantum Bridge VM: Billed as a standard ephemeral compute instance while the backup job is active.
Druva automatically deletes these resources as soon as the backup job finishes to minimize costs. These resources are tagged for easy identification in your Azure Cost Management reports.
How does Druva handle the temporary resources created during backup?
How does Druva handle the temporary resources created during backup?
- Druva uses a fully ephemeral architecture. It automatically orchestrates a temporary database copy and a Quantum Bridge VM for the duration of the backup. Once the data transfer is complete, Druva immediately deletes both resources to prevent "orphan" costs in your Azure environment.
Do I have to pay for data egress when using Azure SQL data protection?
Do I have to pay for data egress when using Azure SQL data protection?
- No. All data transferred from your Azure environment to the Druva Cloud is 100% egress-free. You are only responsible for the nominal Azure infrastructure costs during the backup window. This is regardless of the backup method you are using.
