AOMEI Backupper 7.1.2 does not work for 12TB exFAT volume

AOMEI Backupper 7.1.2 on Win10 22H2: I want to make disk image backup of a Seagate 12TB USB-HD, but although "Intelligent Sector Backup" is selected, and the HD is still almost empty (just 44.5MiB used), Backupper starts processing all 12TB and shows "Remaining: 13hr".


  • @HansS, For exFAT partition, AOMEI Backupper will back up it via using sector-by-sector way by default.
  • Thanks Admin.
    Do you know if eliminating this annoying limitation is already on the todo list for some upcoming revision, or how the wish to solve this problem can be send to the development team? Real support for exFAT should not be too complicated.

  • @HansS, We will submit the suggestion to our dev team.
  • Thanks - let's hope for future improvements :)
