Backup to SD card produces 4103 error
I have a 128GB SD card I use as my Aoemei Backupper Pro backup location. The card is plugged in to the SD slot on my Dell XPS15 Windows 10 laptop.
I can successfully schedule file backups to the SD card, but when I try to schedule a full system backup I get a 4103 failed to write error immediately after a backup starts.
The SD card is exfat formatted with a 128 kilobyte allocation size. For Backupper settings I am using the defaults.
If I use a partition on my hard drive for the full system backup location the backup is successful.
Any suggestions on how to troubleshoot this problem?
