Hi @Mohammed Arkam Ansari Thank you for posting your question on Microsoft Q&A forum. Happy to answer your questions!
I understand that you are using MARS agent backup to back up your Windows machine to Azure. It seems your initial backup was successful, and you want to perform incremental backups.
By default, the very first backup is always a full backup, and the rest are incremental backups. You need to create a backup schedule as per your requirement for the incremental backups to run on schedule. For more details, see this link - https://learn.microsoft.com/en-us/azure/backup/backup-windows-with-mars-agent#create-a-backup-policy
Please feel free to reply if you have more questions. Would be more than glad to answer them.
