Microsoft recently announced the preview of Backup Pre-Checks for Azure Virtual Machines which allows Azure customers to monitor the impact of configuration changes and take steps to ensure the continuity of successful backup operations. Backup Pre-Checks aggregates issues that affect backup and displays it in the Recovery Services Vault dashboard. It even provides recommendations for measures you need to take for successful file-consistent or application-consistent backups. Backup Pre-Checks run as part of the scheduled backup operations for Azure VMs with one of the following states:
- Passed: This state indicates that your VMs configuration is conducive for successful backups and no corrective action needs to be taken.
- Warning: This state indicates one or more issues in VM’s configuration that might lead to backup failures and provides recommended steps to ensure successful backups. Not having the latest VM Agent installed, for example, can cause backups to fail intermittently and falls in this class of issues.
- Critical: This state indicates one or more critical issues in the VM’s configuration that will lead to backup failures and provides required steps to ensure successful backups. A network issue caused due to an update to the NSG rules of a VM, for example, will fail backups as it prevents the VM from communicating with the Azure Backup service and falls in this class of issues.
