Storing files or syncing them to Azure file share? Azure Backup supports Azure file share as a workload and Backup Center (preview) now includes Azure Files backups in its centralised management pane.
Organizations may be looking to use Azure file shares for a number of reasons, such as replacing on-prem hardware or shifting the workload to the Cloud to reduce global connections into one on-prem point. As soon as you mention files, you should have a backup strategy in place that meets your organization's restore point objectives and recovery time objectives - this can range from "we need a file that someone just accidentally deleted" to "we need a file from four years ago as part of an audit investigation." This new capability gives administrators the ability to easily restore individual files, without wrangling an entire storage account or virtual machine backup, and control the costs associated with now only backing up the required file shares.
In essence, the Azure file share sits inside a Storage Account. Azure Backup can now see that file share and create backup snapshots of it, into the same Storage Account. To do this, the Storage Account is registered with a Recovery Services Vault, where the backup policy and retention points are managed.
For important considerations such as supported regions, protection limits, restore limits and retention limits, visit Azure file share backup support matrix.
You can choose the default Daily Policy or create a new one, to tweak the timing of your backup and your retention points. Consider what this policy needs to be to meet your organization's needs and you can create different policies for different file shares. Here I've set weekly, monthly and yearly backup points to be retained.
Restoration is done from the Recovery Services vault, where you will find your Azure Storage (Azure Files) backups. You can restore the full file share or one or multiple files, to either their original location or an alternative Azure file share folder, with the option to overwrite or skip if existing files are found. Choosing the restore point then gives you a list of files available for recovery:
For detailed steps, visit Restore Azure file shares.
Finally, you can track the progress of your restoration, via the Backup Jobs pane in your Recovery Services vault:
And if you need more detailed reporting on a regular basis, visit Configure Azure Backup Reports (preview).
Azure Backup will add a Do Not Delete resource lock to your storage account. As the storage account is used to store the backup snapshots, this is done to protect accidental deletion of the backups. Do not remove this resource lock:
The Azure Portal steps are often easier to make visual documentation from, like this article, but if you're a fan of other methods you can also configure Azure File share backup, restore files and manage your backups with the Azure CLI, PowerShell or the REST API.
Manage Azure File Share backups: Monitor jobs, create a new policy, modify policy, stop or resume protection on a file share, delete backup date and unregister a storage account.
