I've been using Image File Utilities for a while. Mostly it works fine and it was a big help in saving my work on a Raspberry.
Recently I switched to a Raspberry Pi 5. I'm experimenting with Docker images. This leads to quite big images when using Image File Utilities.
I think everything is working fine up to a size of about 6 Gigabytes.
If the image becomes bigger (e.g. 12 Gbyte) I have error messages during the Image-building process. When I check the image with image-check, there are no errors. But when I burn the images to an SD Card, the Pi 5 doesn't start.
Question: Is there an upper limit of allowed image sizes?
Hint: I'm saving to a 1 TB SSD formatted with exFAT.
AFAIK, there is no limit on image file size.
Are you specifying an "Initial image file ROOT filesystem size (MB)" at least as large as the backup will be? The image file cannot expand on the fly during the backup process. Don't worry about making it too large, as it will be shrunk to the smallest size possible when the backup completes.
image-backup uses rsync to do the actual backup. From past reports, it's necessary to disable Docker during the backup.
You might try formatting the SSD as EXT4 to see if exFat is the issue. You might also try using a USB flash drive formatted EXT4 as a test.
