The Estimated size of Full backup is 44.05GB vs 41.07 on Mac HD vs 38.2 on Time Machine ????If you are using Transmission (BitTorrent software), I think it automatically excludes downloads in progress (because they change constantly).
Also, what is the "Estimated size of full backup" in the Options dialog box?
I don't know, but I'd like to wager a guess:I just set up Time machine. It appears that the external HD with Time machine has 38.2 GB of usage and my iMac HD has 41.07 Gb of usage.
Anyone know what the 2.87 Gb difference is between the Time machine usage and the iMac HD?
That would be obnoxiously annoying of Apple to do that.I don't know, but I'd like to wager a guess:
41.07 GB = 38.22 GiB,
where 1 GB = 1000^3 bytes = 10^9 bytes,
while 1 GiB = 1024^3 bytes = 1073741824 bytes.
