Disclaimer: I’m completely new to the backup game, not comfortable with the CLI, using KopiaUI only.
I just completed my first snapshot backup of my external drive to my B2 bucket. In KopiaUI, I see that my volume size is 186.5 GB (which correctly matches the total size of the external drive files I’m snapshotting, when I inspect them in Finder).
However, my B2 bucket size is only 170.5 GB. (I tried snapshotting again and refreshing B2 to double-check.)
Is this possibly due to Kopia’s encryption method containing some kind of compression? Or have I lost data in my B2 bucket?
