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

Wow! Progress is fast nowadays. And that price isn't beyond the moon, either. Thanks. Maybe next year!

I thought a 2TB TM would cover that and more, I need to rethink how I use it, or is it using us?

Wow that was quite a lot of junk!

I’m not all that far behind you at 67. Keep on working the brain lol.

Thanks, but my current backup is only 1.8GB large. So I don‘t think a huge file causes this issue.

It seems to be a sandbox error with the local snapshots in „Volumes“ any idea how to fix that?

I described only my bypass.

It seem that only Apple can fix that by releasing Mojave

It does not surprise me. Out of interest why do you think you need third party security software on a Mac?

It's a bit off topic but for me it's rubbish to think that there are no viruses in the Mac world.

If your mac connects to an office network then it can pass on windows viruses in email attachments to other users and so the IT guys may insist, but your Mac itself is not in danger.

Well, closing all my apps would be fun to try, except TM is backing up on its own every hour, and I'm kinda working. But backups seem to be working again.

It worked only once, so NightOwl wasn‘t the issue. I tried to backup in safe mode, so no app is running in the background, but it still didn‘t finish.

Does it ever stop? The only real error message is that there is no room left on the backup device.

You can check the status over the backup process.

For example, mine says "23Gb out of 258Gb" and when you near 250Gb then both values grow:

251Gb out of 263Gb

252Gb out of 265Gb

etc...
