 #### Automatic Retry of Failed Backup Jobs
 
-Many of the failure errors or the outage scenarios are transient in nature, and you can remediate by setting up the right Azure role-based access control (Azure RBAC) permissions3 or re-trigger the backup/restore job. As the solution to such failures is  simple, that you don’t need tp invest time waiting for an engineer to manually trigger the job or to assign the relevant permission. Therefore, the smarter way to handle this scenario is to automate the retry of the failed jobs. This will highly minimize the time taken to recover from failures.

Therefore, the smarter way to handle this scenario is to automate the retry of the failed jobs. This will highly minimize the time taken to recover from failures. 
 You can achieve this by retrieving relevant backup data via Azure Resource Graph (ARG) and combine it with corrective [PowerShell/CLI procedure](/azure/architecture/framework/resiliency/auto-retry). 
 
 Watch the following video to learn how to re-trigger backup for all failed jobs (across vaults, subscriptions, tenants) using ARG and PowerShell.
