Azure Backup and Site Recovery (Business Continuity Center) Flashcards
I want to back up the on-prem VM (Windows) to Azure; how can I achieve this?
You can install the MARS agent that when configured will backup to Azure Backup Vault?
I want to backup Azure VM (Windows) to Azure , how can i achieve this?
In the Azure Portal on the VM there is a option to enable backups
Can you move vaults between subscriptions?
Yes
What is the redundancy model for Azure Backup and Recovery?
You chose at vault creation if you want you data in a single zone, multiple zones or in a geo-replicated.
What is Business Backup center?
What is a backup policy?
An Azure Backup Policy is a set of rules that define how and when backups are taken for Azure resources such as virtual machines, SQL databases, and file shares. It helps automate the backup process and manage data retention and recovery. Here are the key components of an Azure Backup Policy:
Backup Schedule: Defines when backups are taken (e.g., daily or weekly) and the frequency of backups (e.g., once a day, twice a day).
Retention Policy: Determines how long each backup is kept. Azure supports retention based on days, weeks, months, or years, allowing for long-term or short-term retention as needed.
Backup Type: Specifies the type of backup, such as full backups, incremental backups, or differential backups, depending on the resource being backed up.
Recovery Points: The policy specifies how many recovery points (snapshots or restore points) to keep and how they are maintained over time.
Instant Restore: For certain services like Azure VMs, the policy can include an option for instant restore, which allows rapid recovery from a snapshot.
Geo-Redundancy: You can choose the type of redundancy (local, geo-redundant) for storing backups, ensuring that they are available across regions if needed for disaster recovery.
When backing up an AKS cluster, what data is been backed up?
- Cluster Metadata: This includes the AKS cluster configuration, such as resource settings, identity settings, network configuration, and other metadata related to the AKS control plane. The metadata allows for recreating or restoring the cluster configuration.
- Persistent Volumes: Azure Backup focuses on backing up data stored in persistent volumes that are attached to the AKS cluster. These persistent volumes store the stateful data used by the applications running within the Kubernetes cluster. Azure Disks (used as persistent storage) are a key component here.
- Application Workloads: While Azure Backup doesn’t directly back up application containers or pods, it ensures that the stateful workloads (i.e., applications with data stored in persistent volumes) can be restored.
When backing up an AKS custer are you backing up, the container images?
No, images are not able to be backup container images.
Can you use Azure Backup to backup Azure Storage Blobs?
Yes, you can use Azure Backup to backup Azure Storage Blobs.
Can you use Azure Backup to backup Azure Storage Tables?
No, you can not use Azure Backup to backup Azure Storage Tables.
Can you use Azure Backup to backup Azure Storage Files?
Yes, you can use Azure Backup to backup Azure Storage Files.
Can you use Azure Backup to backup Azure Postgres DB?
Yes, you can use Azure Backup to backup Azure Postgres DB.
What are the supported backup redundancy tiers for storing data?
- LRS
- ZRS
- GRS
Do you need to provision storage when using Azure Backup?
No, you just create a vault and Azure takes care of provisioning the storage you need.
When would you use LRS with Azure Backup?
To protect agenized server rack or drive failures, data is replicated with in a single zone three times.
