What´s the difference between these two types of Backups? I have a full backup of HD C: normal compression, size: 3.5 gb. I tried to take a new backup with new installed software. acronis recommends to do an incremental backup with less space. Now the new backup file taken is about 4 gb now i have two image files: the original with 3.5 gb and the supposed incremental one with 4 gb Is this the right way how acronis works?
