How to take Azure VM Application consistent backup RRS feed

Answers

  • As stated, by default, Azure Backup takes full VSS backups. That being said, you don't necessarily have to add the reg key. That settings are required for using SQL Server VSS copy backups.

  • In Azure, Windows VM backup is by default application consistent. However, it is file system consistent for Linux VMs unless you use pre & post scripts

    If your Windows VMs show up as file-system consistent that could be because of VSS writers failing. You can run command "vssadmin list writers" on command prompt to list all the installed VSS writers and their state. If you notice any writers failing, you need to fix it. Also, restart Volume Shadow Copy service if problem persist.

  • Thank you very much  SadiqhAhmed-MSFT 

    Just one question, So on windows VM, Do we really need to add  below to take the application consistent  backup? 

    REG ADD "HKLM\SOFTWARE\Microsoft\BcdrAgent" /v USEVSSCOPYBACKUP /t REG_SZ /d TRUE /f

    As per the https://docs.microsoft.com/en-us/azure/backup/backup-azure-vms-introduction,
