Mojave time machine back up failing

Since installing 10.14 have not been able to complete a full backup using time machine to external drive. All disks check out on disk utility first aid both under OS and stand alone utility under recovery. Have erased and reformatted the external drive. Still no success. Backup begins and runs up to about 80GB ok, then fails. Restart by "back up now" continues for about 500MB and then fails again. My full backup is about 900GB so I am running unprotected.

I believe this is a Mojave problem, not a drive problem.

Any ideas?

Mac mini, macOS Mojave (10.14), Samsung display

Hi guys,

I'm the developer of this application.


I apologize for the inconvenience you could have with the issue.

We have prepared the application update with the bug fix and sent it to App Store. Now App Cleaner v.6.2 update is being reviewed by Apple. I hope Apple will approve and release the update to App Store in a few days.

Since update v.6.2 is released and launched the folders will be removed, the issue will disappear.


Now, there is a simple way to bypass the issue - just add the folder

"~/Library/Containers/com.nektony.App-Cleaner"

to Time Machine exclude list.


The detailed guide how to exclude the folder from backups that is available on our website

Regards,

Serge

BTW - I just ran Etrecheck and my late 2013 MaBook Pro did not indicate any major or minor problems other than a warning about future problems may occur with a couple of 32 bit apps. I didn't expect there to be a problem but one other possibility eliminated for me. My Time Machine is connected to a 1 TB WD drive with two partitions, the smaller one for a few movie downloads. The drive uses GUID and is HFS+, Journaled as it should be. The drive I am using now has been in use for two years without a problem other than making restarts and slower switching to bootcamp more noticeable for the past year. I have an alternate drive that I use to alternate with on a monthly basis. I do that for hardware redundancy and it now offers me the option to restore my previous High Sierra in a simple and reliable manner as Time machine no longer works with Mojave. I will simply reformat the drive with the former APFS I have been using and than restore with my month old Time Machine. Any month old files in Document, Photos or Music that are lost can be restored from my Google drive and any app updates will come from Apple or my other sources. I doubt there is more than one or two.


Time Machine worked well on my 2011 Mac Mini over a year ago when I installed a 500 GB SSD. I was very impressed with Time Machine as it was a perfect restore and effortless with the exception of the few hours needed for the actual restore. I didn't have to nurse anything along or migrate a **** thing.

This does indeed work. Now all they need to do is fix it. but for now it is a great work around.

Thank you!


Now if the whiners would read the posts instead complaining so much. Yes it stinks, but any new version of OS has the potential of major bugs. This bug aside, this has been a very stable release overall. We took the risk of being guinea pigs by impatiently installing a brand new version and yet some of us expect it to be flawless? 😮 psssh.

And yet since the beginnings of software development, there will always be bugs that slip thru the cracks, always. This is nothing new. It is, what it is. I guess I still have a lot to learn about the internet and forums. I spent hours with apple care working on this issue. It is important. But i also take responsibility for my hasty and stupid decision to jump aboard a brand new os thinking it was going to be bug free. It is a gamble, anyone that's been around long enough knows this. Betas find most problems, but not all. You can not be that naive to think a gm release would be or even should be bug free. They never have and probably never will. Its almost impossible and impracticle to expect as much from a fresh software releases. Glad there is a work around. Now life moves on.

What is odd is that it didn't happen to me until over week passed since I clean installed Mojave. Maybe thats why it didn't get picked up during the betas. Also, most people probably didn't bother with time machine during the beta because they were just fiddling around with it on a separate partition. no reason to back-up a beta. I dunno. just a hunch.

I also use this app, and TM never had a problem to work.

But anyway how the breaking space will come to the problem, a mistake every programmer knows, inside the TM routine should be an expression which solve errors like that, even UTF8 or things like that.

It is not understandable and we will see how long it takes until mojave will work proper.

Its our mistake at all, never change a running system and never jump to an update X.X always wait until X.X.3 or 4, thats what i did in the last 10 years, but my machine had a problem that it gets the spinning wheel all the time and i hoped the update will fix it.

It dosn't, now the wheel is all 30 seconds :-(

But then you loosing all data at all, you have to have a working backup better two or so, because dataloss is worst, AND all users with Fusiondrive cannot easely make a Cleaninstall, cause the Fusiondrive is not deletable. ;-)

Not that easy.

And Apple has no handout what to do exactly!

You need help from the net to work over the terminal.

And there is no Garantie that the spinning wheel will not come again.

I dont know what you are doing on your machine, but mine is pretty full of stuff which i need to work with.

At he end thats always just little things which are creating this problems, never big ons, because the will be find easely
