Tip: Running a Trim right before the backup saves a lot on the image file size for me.
Update after more experience:
1. When I made backups of my ~80 GB (9 GB used) Linux EXT4 partition on an NVME SSD, it worked fairly well and resulted in a ~2.7 GB backup image.
2. With an ~80 GB (9 GB used) Linux EXT4 partition on a mechanical HDD, it resulted in a massive 68 GB backup image. No good!
Not sure why the type of hard drive it was on made a difference, but it did. Because no TRIM on HDD so the entire space was seen as "occupied" by data? Anyway, Macrium v8.1 handles it well, Hasleo v5.*, not so much.
