Initial backup never completes. Backup size keeps increasing as it backs up!
I am trying to backup my new MacBook Pro (2017 model, fully up-to-date OS) using Time Machine. The initial backup NEVER completes as the backup size keeps increasing. I have tried this on THREE different Time Machine Backup disks, and the problem is always the same. The issue clearly is with the computer and I have no idea how to fix it. HELP ME PLEASE !
Here are some details:
- Macbook Pro 256GB SSD (2017 model, still under warranty). Disk currently about 80% full (200GB or so)
- Time Machine Backup disks:
All the above backup drives have been used or are currently being used as Time Machine backup drives for my other computers. All are formatted correctly (extended, guid, etc)
So, here is what's been happening, every times the same, one each of the above drives:
The initial backup starts fine, then stops after a while. Upon restarting, the backup size keeps increasing, making it impossible for the backup to ever complete. You can see the stupid thing in action here: https://www.youtube.com/watch?v=cENrS7e4bZg
The difference between the two is about 10%, regardless of the size.
Yes, I tried different disks.
Yes, I restarted and updated everything with latest firmware and OS updates.
Yes, the drives are correctly formatted.
Yes, I deleted the backups, formatted, rebooted, restarted.
I've let the last option (backing up to the freshly-reformatted-to-Mac-OS-Extended-(Journaled) external USB HDD) running for 36 hours now. This MacBook Pro's 256GB SSD has already filled up 1.15TB of space on the drive, still not having completed its initial backup.
So... Any ideas/suggestions/anything from the community? I know I'm not the only one in this situation, but no other help thread has yielded any results so far, so here I am!
Thanks!
MacBook Pro with Retina display, iOS 11.2.6, Time Capsule
