Also, to ensure timely and reliable restores from backups, a maintenance plan should be in place. This involves regularly troubleshooting the backups as well as proactively testing restorations for critical files and data sets to ensure their recoverability. Finally, restore strategies must also include properly storing archived backup media in order to reduce potential risks of failed recovery attempts due to improper storage conditions or mishandling of the tapes themselves.
Azure Backup is a cloud-based backup solution that helps protect data and applications from human errors, hardware failures, and other disasters.
To set up Azure Backup, you need an Azure subscription, a Recovery Services vault, and a VM that you want to back up.
A backup policy is a collection of settings that define when and how to back up data. It includes settings such as backup frequency, retention period, and backup window.
To create a backup policy in Azure Backup, you can use the Azure portal, Azure PowerShell, or Azure CLI. In the Azure portal, navigate to the Recovery Services vault that you want to configure, and then click on Backup policies to create a new policy.
A backup policy schedule defines the frequency and timing of backups. You can choose to back up data daily, weekly, monthly, or at a custom interval.
A retention range is the period of time for which backup data is retained. You can choose to retain backups for a few days, weeks, months, or even years.
A backup window is the time period during which backups are scheduled to occur. You can choose a specific time window when backup operations will be least disruptive to your workloads.
An application-consistent backup ensures that the data is backed up in a consistent state, which means that the backup captures all in-memory data and metadata at the time of the backup.
A recovery point is a snapshot of the data that has been backed up. You can use recovery points to restore data to a specific point in time.
A Recovery Services vault is an Azure resource that is used to store backup data and manage backup policies. You can create a Recovery Services vault in the Azure portal or through Azure PowerShell or Azure CLI.
