Powernap/Time machine stalling when asleep

2012 Macbook Air, latest OS X, latest updates including the firmware update from yesterday.

Ever since a recent restore, remote time machine backups to my time capsule and drives attached to my time capsule haven't been working while my MBA has been asleep. After a number of trials, I can for the most part assume Power Nap is working since I receive emails while the machine is asleep.

However, Time Machine backups seem to start while the machine is asleep and only finish when I wake the Mac the next day. Looking in the logs, there are numerous instances of "Bulk setting Spotlight attributes failed."

Research says this can be a problem with the indexes, any number of various things. What it looks like, however (I assume), is the backup starting when the machine is asleep and then losing the connection to the time capsule

I've tried deleting and reindexing the spotlight index, repairing the drives in disk utility, making new backups from scratch, restoring the mac again, reinstalling OS X and using migration assistant to restore my data, running diskwarrior on both the backup disks and even buying a new external hard drive to test with. Nothing seems to work.

Seriously, this has been going on for 3-4 weeks now and I can't figure out what the problem is. It was working fine before I had to restore the Mac for an unrelated issue!

Please, I hope someone has a clue?

Here's an example log from last night polled from Time Machine Buddy

I had the right speaker replaced because it was distorted. I did a complete flatten reinstall to be sure some app wasn't messing around with the sound. It was determined to be the speaker itself and it was replaced. Aftewords I did a migration assistant restore to get my stuff back but since then I've done the same and regular time machine restores to try and solve the tm problem

I've been living hell with a similar issue now for months... Apple had my laptop and TC for a month and could not figure it out... Now after changing my laptop and then using Migration Assistant to get documents, iphoto library, itunes library back... the problem remains!

Backups work A OK when powered on and complete in 2-3 minutes but take 3-4 hours in powernap and have indexing errors... I'm about ready to rip my hair out of my head!!!

Praying you have an answer,

Unfortunately I don't have a solution and apple couldn't tell me much. Every few months I come back to see if there is any more news on how to fix this... but still nothing. I usually get one backup being made after it goes to sleep with tons of "Bulk setting spotlight attributes failed" messages.

These backups restore fine and everything too.

Oh, AND I now have the 802.11ac time capsule and still with these messages and no backups while asleep. What the heck is going on?
