I backed top my MBP the other day and downloaded High Sierra with no issues.

Since all was working well, I decided to back up using TM, but keep getting an error notice.

Do I have to reformat my back up drive?

Thank you,
m

What's your exact error?

TM should continue to work after HS upgrade. No need to do any reformat.

I've had this from time to time. The easy fix is to delete TM backups and start a new one from scratch which will work, but then you loose all the old backups unless you off load them on to a spare disk.

I just went into disk utility and ran first aid on my back up drive, and TM is working now; I should have done that first!!

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?

I had the same symptoms. My TM is a USB on a network computer that shares it. I rebooted that and verified the TM-drive. After that TM started to work again.

[doublepost=1526051833][/doublepost]Mine is exactly the same and still cannot find a way to mend... even after the last update. Any ideas?

My time machine always has a problem...I just connect it to the mac via USB and is not showing up anywhere. The wireless is putting out a wifi signal but that's it.

TM SEEMED to work fine for me under HS, but when I needed it.... It kind of faild. I restored my primary drive and all looked good until I tried to reboot. I then had a non-bootable drive. Error stated the drive wasn’t or couldn’t be blessed.

I reinstalled clean and migrated the TM data. In that way, it did work.

I have moved on to CCC for now. It seems to be a better solution for me.

1000% CCC is a much better options for bootable (or whole partition / system) backup solution.

TM is a nice backup tool, but IMO, that's the best to recover single (or small amount) missing file (and folder). It's UI is so easy to use if you want to search and recovery a particular file.

However, for whole OS partition. TM is slow, unreliable, hard to use (the back up itself is not bootable).

Also the down time to recover the whole OS can be ridiculous long (it costed me 30hr to recover a OS partition that greater than 1TB). By use CCC, there is virtually no down time, and much faster to finish the recovery process.
