@Naresh Babu Yes, there are ways to back up your Azure Automation account before deleting it. Here are some options:
- Export Runbooks to Script Files: You can export your runbooks to script files using either the Azure portal or the Export-AzAutomationRunbook cmdlet in Windows PowerShell to your local computer. You can import these script files into another Automation account.
- Note Asset Details: You can't export Azure Automation assets, certificates, connections, credentials, schedules, and variables. Instead, you can use the Azure portal and Azure cmdlets to note the details of these assets. Then use these details to create any assets that are used by runbooks that you import into another Automation account.
- Export DSC Configurations: You can export your DSC configurations to MOF files using the Export-AzAutomationDscConfiguration cmdlet in Windows PowerShell. You can import and use these configurations in another Automation account.
- Export Node Configurations: It isn't possible to export node configurations, or compiled MOF files. If you published MOF files directly into the Automation Account and no longer have access to the original file, you need to recompile from your private configuration scripts. If you can't find the original configuration, you must reauthor it.
- **Integration modules :**You can't export integration modules from Azure Automation, they have to be made available outside of the Automation account.
