[QUOTE="MacInWin, post: 1825912, member: 396914"] Well, it's been an adventure. Started the backup, as I said in the post #13 at 7:10 today, just a few minutes after 6 pm. It just finished for the second device. So that took 3 hours to do two backups totaling 250GB. Not fast, but at least it finished. Now for the results: The iMazin folder in ~/Library is 88MB, down from 200+ GB. The target drive where the backups are now shows 240GB using "du -h" in Terminal. Finder thinks that's 323GB, which is consistent with what DigiDNA said about space being double counted in macOS and Windows. So, the lesson seems to be that if you install iMazing and just go with defaults, you could find that it will take a lot of disk space as it builds backups on backups. And, to me more importantly, if you start with the default and switch to an external later, as I did, it won't erase/release that internal space when you do that. So, my recommendation is that you decide where you want backups before you install iMazing, set that in Preferences before you attach any device. My SSD now has 200GB more free space than it did before I started this exercise and I am a happy camper. [/QUOTE]
