Insufficient Space Error

Backupper 4.1.0, 710GB used on computer, 3.7TB available on backup drive. When attempting system backup, Step2 states "The disk space on the selected partition may be insufficient." Why? How can I get this to work?


  • Did you encrypt the drive? Is it NTFS or FAT32?
  • NTFS, not encrypted. Worked once a few months ago, fails now.
  • If you believe the disk space is sufficient, you could ignore the message and click the Start Backup button.
  • Did that - there was no backup made. Folder is made, but empty. "Backup" takes less than one minute.
  • Can you try a small file backup to see the result?
