High Sierra and Time Machine Backup

Time Machine can apparently get stuck for mysterious reasons. I would just leave for a day or two to sort out.
My Time Machine does not give any errors, and seems to backup all data without issue, however since updating to High Sierra, the automatic hourly backups no longer work. TM only runs when I log into my computer.
Example, after I'm away for the day it shows last backup was at 8am (which was about an hour after I was last logged in), so it completed a backup while I was logged in and then one more an hour after I put it to sleep, and that's it. As soon as I log back in it starts to backup without me doing anything, and will continue as long as I'm using it, but once it goes to sleep the hourly backups don't run except for once after last sleep, I never had this issue before the upgrade, hourly backups always worked flawlessly. It's been 3 days, no change. I have rebooted, no difference.
Anyone experiencing this with TM not auto running in sleep?

Mine also does not run while asleep. But is this a real problem? Seems to me if the mac is asleep then there aren't any changes occurring therefore no need to back up what hasn't changed?
I'm having serious issues with Time Machine (backing up to a Time Capsule from 2012 rMBP) since High Sierra. It frequently gets stuck on "preparing backup" for 10 minutes or more, and sometimes will backup partway and then stall until manually restarted. I never had this issue before. Suspect this is related to the change to APFS.
Time Machine was totally messed up after installing High Sierra; it would report a successful full-disk backup (to a freshly formatted Time Machine drive), but was actually only backing up a tiny fraction of the drive's contents. I ended up having to purge all local snapshots, and then manually rebuild the snapshot count, to get it to do a complete full backup again.*
*I needed a full backup because High Sierra also messed up the APFS conversion, and while it managed the switch from HFS+ on the OS partition, it broke the container in the process which meant I couldn't resize the partition. A full wipe and restore from Time Machine backup fixed it.

Did this fix your issue? Are you back to normal backups now? I may just erase the old backups on Time Machine and start over.
I'm also experiencing the same problem with one of my Macs (Both on High Sierra). I am sharing a 2 time machine drive through a High Sierra server. I thing the problem origniate from the client side… but I don't have the skills to go further for now.
