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

Serge

Ok, i understand, thanks, in my opinion i understand as "clean" install a fresh virgin system without data at all an then install thing by thing.

I will do the "clean" when my Carbon Copy Cloner Backup will be done, which is also broken before on The App Cleaner & uninstaller folder.

Strange.

So we have two "bandits" found - the app and the case sensitive thing.

Adobe had this for years also i remember.

Yes obviously TimeMachine is screwed big time. It keeps growing in parallel of the whole backup process.

So there is a temporary folder involved in the TM process that has to be excluded, but it's not /Users/name/Shared/adi like it used to be before Mojave.

I just relaunched TM and it pretends to be backing up 6Gb out of 7Gb...

After 3 minutes it already states 8.26 Gb out of 9.2Gb

After another 3 minutes: 11.2 out of 15Gb...

This is totally stupid.

I have never used the encryption option. The initial backup was about 550 GB on a 2 TB drive. The hourly incremental backups are fairly small and I still have 1.43 TB free on my backup disk. If it is going to run out of space it will take quite a while, like several months. By design, Time Machine should delete the oldest backups to make room for the newest. Note that I don't have the Uninstaller app that other people are excluding/removing on my Mac. The uncontrolled growth issue sounds like another Time Machine bug. Hopefully, Apple will fix all these bugs sometime soon.

Hello Serge, just deleting the version 5.4 folder works fine as well and you don't have to exclude the version 6 one from your Time Machine backups.


PS : Out of the subject of this discussion, your App-Cleaner-Helper app is strangely named in Activity Monitor : $(PRODUCT_NAME). Nothing problematic I guess but quite unusual to be mentioned.


Thanks

Alex

Peter,


The Containers folder is in the Library folder under your User's home directory. Are you sure you are not looking in the System Library folder?


There is a difference between this: /Library


And this: ~/Library


There is no Containers folder in the system Library folder found at "/Library".


CDMBPro:~ cdowney$ ls /Library/ | grep Containers
CDMBPro:~ cdowney$ ls ~/Library/ | grep Containers
Containers
Group Containers
CDMBPro:~ cdowney$


~ denotes you are in your User's home directory, which fully qualified would be equivalent to "/Users/<YOUR_USERNAME>". The fully qualified path of the 2 App Cleaner folders to clear out would be:


"/Users/<YOUR_USERNAME>/Library/Containers/com.nektony.App-Cleaner/Data/Library/ Application\ Support/"

These workarounds are great but I am concerned that Apple is not correcting the root cause of the problem. If a software vendor's folder naming misstep is allowed to break Time Machine something is seriously wrong with the underlying utility, i.e., Time Machine. At the very least Apple should alert the user of the problem in a user friendly way and continue to backup all non-offending folders and files. To break the ENTIRE backup process due to one vendor's issue is simply wrong and puts end users at risk. What, if anything, is being done to alert Apple about these issues so they can fix the real problem?

I just wanted to chime in that I'm having the same/similar problems. After comments on this thread, I took a deep breath and erased one of my two Time Machine backup drives and reformatted it from Mac OS Extended (Journaled) to Mac OS Extended (Case-sensitive, Journaled) to see if that would work.


It didn't.


About five times now, over 24 hours, Time Machine has gone for many hours copying hundreds of GB before stopping without warning. My Time Machine drive now contains one inProgress file that's been stuck at 895.46 GB since throughout the last three backup attempts.


Disk Utility says my backup drives are fine. Also, backup has been consistently failing on both my backup drives since I upgraded from Sierra to Mojave (I skipped High Sierra). It was backing up flawlessly before then.


I've got 3TB of storage in my 2012 Macbook Pro, across a 1TB SSD and a 2 TB HDD (living in my old DVD drive space). Mojave reformatted my SSD to APFS but kept my internal HDD as Mac OS Extended (Journaled). I wonder if that's got it confused.


Should I reformat my internal HDD as APFS and try again?


Sigh.
