TAPB (Yet Another Preparing Backup) [Time Machine] thread - deckeda - 09-27-2016
2-3 yr old MacBook running Sierra. 22 days since the last Time Machine backup, via USB-connected external hard disk.
256MB of 18GB done, and then a stall for many hours. Can't fathom why there would be 18GB of stuff needing backup, on a Mac that hadn't been used for 3 weeks, but whatever.
Impatient, I rebooted it, tried again, and now it's "preparing" for quote awhile.
LET IT RIDE, is the the time-honored advice. No biggie. And I've got no problem with wiping the drive and starting over with an all-new Time Machine backup.
But, it's 2016 and this crap is annoying.

When a problem with the drive or the backup is detected or if it's simply been a long time between backups, backupd will do a deep-traversal scan.
Let it chug.
...As for why you might have 18GB of backups to do, perhaps about 12GB of that is your new operating system?

I don't understand. Sierra, installed, weighs 12GB more than El Cap? Even if the installer was kept, which it wasn't, that's a huge difference, no?
I stopped it, when it got stuck in the same spot as yesterday. There's no chugging happening after that point.

Keeps trying each hour but haven't been watching it during those attempts. "Last backup Sept 4"
Seems as if it's trying, failing and trying the next hour.

I erased the external disk. Now, Time Machine is working.

12GB of new/changed system files to back up.
