I have a weekly incremental backup with Azure Backup.
What happens to this backup if the previous backup was not completed at the start of the backup? Twice
(Will this backup start after it is interrupted and the previous backup is complete, or will it be aborted and run?)
Regards,
Is this manual backup or automatic backup? Azure vm or Azure sql db? What kind of backups? – If I cancel a backup job after it starts, is the transferred backup data deleted?
No. All data that was transferred into the vault before the backup job was canceled remains in the vault.
Azure Backup uses a checkpoint mechanism to occasionally add checkpoints to the backup data during the backup.
Because there are checkpoints in the backup data, the next backup process can validate the integrity of the files.
The next backup job will be incremental to the data previously backed up. Incremental backups only transfer new or changed data, which equates to better utilization of bandwidth.
If you cancel a backup job for an Azure VM, any transferred data is ignored. The next backup job transfers incremental data from the last successful backup job.

I have a VM and I want to be able to copy a large amount of files to a backup drive. I have remote desktop and tried to copy that way , but the copy halts and gives no error.
The size is about 120G of data ?
Copying files larger than 2 GB with RDP isn't supported. Check this article for details.
As an alternate option, you could try using the Azure Backup service if you intend to back up your Azure VM. Backups are stored in a Recovery Services vault with built-in management of recovery points. Configuration and scaling are simple, backups are optimized, and you can easily restore as needed.
As part of the backup process, a snapshot is taken, and the data is transferred to the Recovery Services vault with no impact on production workloads. You can also schedule your backups to a suitable time so that resources are optimally used.
I currently have a Backup job in progress in Azure...File and Folder level only. I need to stop the job it has been running for too long. How can I stop it.
In Azure Storage (Azure Files), you can go to Azure Files > Backup > select the ... > Stop Backup.
You can also stop a backup job through Powershell.
Stop-AzureRmBackupJob

To stop backup on a VM, you can go to the vault item's dashboard and select one of the following:
Stop protection and retain backup data. This option will stop all future backup jobs from protecting your VM; however, Azure Backup service will retain the recovery points that have been backed up. You'll need to pay to keep the recovery points in the vault (see Azure Backup pricing for details). You'll be able to restore the VM if needed. If you decide to resume VM protection, then you can use Resume backup option.
Stop protection and delete backup data. This option will stop all future backup jobs from protecting your VM and delete all the recovery points. You won't be able to restore the VM nor use Resume backup option.
I am having an issue creating differential backups of Azure SQL database in storage account blob storage using powershell. I don't know if it is possible or not to get a differential back up of an Azure SQL database. Please suggest me what can I do.
If have seen the differential backup document, you will find this:
Azure SQL database has the feature Automated backups. It referred that:
SQL Database supports self-service for point-in-time restore (PITR) by automatically creating full backup, differential backups, and transaction log backups. Full database backups are created weekly, differential database backups are generally created every 12 hours, and transaction log backups are generally created every 5 - 10 minutes, with the frequency based on the compute size and amount of database activity. The first full backup is scheduled immediately after a database is created. It usually completes within 30 minutes, but it can take longer when the database is of a significant size. For example, the initial backup can take longer on a restored database or a database copy. After the first full backup, all further backups are scheduled automatically and managed silently in the background. The exact timing of all database backups is determined by the SQL Database service as it balances the overall system workload. You cannot change or disable the backup jobs.
I also asked Azure Support, they told me that we(customer) can not create the differential backup by ourselves, Azure SQL database will do that automatic.
Hope this helps.
I am attempting to create a maintenance plan for a local transaction log backup.
The location of the full backup is listed as an Azure address ({C58FA3E7-ABB7-........}) so the maintenance plan thinks there is no full backup.
Is it possible to still create the local transaction log backup without access to Azure?
Right now the only way I can get the tlog backups to not fail is if I create a new full backup manually on the local disk.
I understand Windows Azure Backup Agent performs incremental backups by tracking file and block level changes and only transferring the changed blocks, but my question is how does it track those changes?
The reason I ask is we are using Azure Backup as a off-site backup only, and are still planning on using our current Backup Appliance to backup locally.
I want to make sure that neither backups will conflict with the other, or mark that a file has been backed up on one system, and prevents the changes from being backed up on the second system.
Azure Backup agent leverages USN journal capability of file system to find the changed files. Ensure that latest Azure Backup agent is installed.
