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

It's under your user, not at the top of the MacintoshHD.

Users/[your name]/Library/Containers

The Library is hidden by default.

To show it, open a desktop window and either:

1- Select the GO menu and press the alt/option key. Library will appear

or

2- Click on your name (your environment) on the left side and press Shift-Cmd-. (period) This will show hidden files and folder.

You should be able to see Library and then Containers.


Don't forget to press Shift-Cmd-. again to hide back those essential folders, to make sure not to move or delete them by mistake.

Why third party security? Out of long-established habit, really, and perhaps originally (years ago) recommended by tech specialists at work. Not sure about the ins and outs of the matter, but it's always extra security, isn't it? It's free, and I know Sophos is a very reputable company and while I know PCs are much more exposed I occasionally read here and there that Macs are exposed too, arguably more so than in the past. Also, apart from this backup hiccup, I do not think there are any counter indications or down sides to having Sophos security. But would be interested to know more, if you or others have any relevant information.
