Q: Is it normal for Time Machine to want to back up 15 gigs after updating to new OS X?
I just updated my Mac to the latest OS X El Capitan 10.11. I am conducting the first backup to my Time Machine since I upgraded but the upgrade is 15 gigs! Is this normal? I don't have very many files on my Mac or iCloud so when I first got the Time Machine the backup only took about 30 minutes so I'm a little confused and worried.
Thank you!
MacBook Pro (Retina, 13-inch,Early 2015), OS X Yosemite (10.10.3)

15GB sounds spot on..
Remember the entire backup needs to be replaced.
And I would encourage you to backup to a different name or location so you don't smash your existing backup.

TM backs up at about 50-60GB per hour to network drive like Time Capsule.. that means in the first backup your computer stored 25-30GB of files.. and now you are worried about 15GB.
