Creating and Configuring Backup Policies in Microsoft Azure is an essential skill every administrator should have, moreover, it’s crucial for candidates studying for the AZ-104 Microsoft Azure Administrator exam.
Overview of Azure Backup
Azure Backup is a built-in service in the Azure platform, providing simple, secure, and cost-effective solutions to back up your data and recover it from the Microsoft Azure cloud. It offers a wealth of features, including automatic storage management, unlimited scaling, multiple storage options, data encryption, application-consistent backup, and centralized monitoring and management.
Creating a Backup Policy
In Azure, a backup policy is used to define when and how your Azure VMs should be backed up. The first step is to create the policy.
Here’s a step-by-step guide:
- Navigate to the Azure portal.
- On the left-hand menu, select ‘All Services’, then search for and select ‘Backup Center’.
- In the Backup Center dashboard, you will see the ‘Backup Policies’ section. Click on ‘+Add’.
- You will need to fill in details for the backup policy. These include:
- Policy Name: A unique name for the policy.
- Backup Frequency: How often backups occur (daily or weekly).
- Backup Time: Time of day when backup should start.
- Retention of Daily Backup Points: The number of days to retain a daily backup.
- Retention of Weekly Backup Points: Number of weeks to retain a weekly backup.
- Retention of Monthly Backup Points: Number of months to retain a monthly backup.
- Retention of Yearly Backup Points: Number of years to retain a yearly backup.
- Days of the week for Weekly Backups: Which days are chosen for weekly backups.
- Weeks of the month for Monthly Backups: Which weeks are picked for monthly backups.
- After specifying all the details, click on ‘OK’ to create the backup policy.
Here, you need to remember that the Backup frequency (daily/weekly) and times are related to the time zone of the region where the vault is located.
Configuring a Backup Policy
Once you create a backup policy, the next step is to configure it. Note that you can configure a policy while creating a new VM, or for an existing VM.
For creating a new VM:
- Navigate to the Azure portal.
- Click on ‘Create a resource’, then select ‘Virtual machine’.
- Fill in the details for your VM and click on ‘Next: Disks >’.
- In the Disks tab, under ‘Data disks’, click on ‘Create and attach a new disk’.
- In the ‘Create disk’ page that opens, specify the details for the disk, and then click ‘OK’.
- Return to the VM configuration page and click ‘Review + Create’ to start creating the VM.
For an existing VM:
- Go to the Azure portal.
- In the left-hand menu, select ‘Virtual Machines’.
- Click on the VM for which you want to configure the backup policy.
- In the ‘Operations’ section of the VM’s menu, click on ‘Backup’.
- In the ‘Backup’ page, you can select the backup policy from the drop-down list.
- Click ‘Enable Backup’ to apply the selected backup policy to this VM.
Remember, when you enable backup for a VM, the initial backup will run in accordance with the specified policy.
In conclusion, getting familiar with Azure Backup and understanding how to create and configure backup policies is crucial for every Azure Administrator and those preparing for the AZ-104 exam. With proper configuration, Azure Backup offers a robust, secure, and straightforward service for safeguarding your data. Always refer back to the official Microsoft documentation for Azure Backup to stay updated with any changes or new features.
