Aomei Backupper Pro always performed full backup in scheduled incremental disk backup

I have a issue with scheduled incremental disk backups. It always performed full backups.

Here are my settings and log details.


Please help me.

Thank you.


  • Delete the backup task. Create a new backup task, use new backup folder.
  • @Anuruddha, Yes, please recreate the backup task to check again.

    @admin thank you for your reply. It starts to work automatically. Now I have a new issue. Non of my backups are deleted. I have 20TB hard drive and it's is full now. AOMEI can't backup anymore. It fails every backup with  Error Code: 4138(There is not enough space on the disk.)
    Description: Failed to complete the operation. I'm using windows 11 Pro.

    Please help me.

    Thank you
