Mojave time machine back up failing

Thanks you for this, I'm going to try the alternate backup. I expect some software not to work with a new system software update but expect Mac software to work with a Mac system update. I'm going to keep my current backup drive as is and get another one to start new backups in the hopes that the Time Machine issue will be resolved at some point. Not crazy about buying a new external to solve this problem.

I confirm that despite the macOS 10.14.1 update the TimeMachine problem of it growing up indefinitely IS NOT FIXED at all.

Same for my 2 other upsetting bugs: vertical lines appear as dashes when windows overlap, and iMessage always remembering what you typed lass, and puts it into the app into the typing area for you to send it again (always have to empty the typing area).

Just what was this "upgrade" worth then? Emojis? That's it?

I’ve been on the phone with Apple Care twice, only I person said she had seen this problem, suggested I reload Mojave’s, no luck. Recommended reformatting disk, did not do, has over a years worth of backups. Suggested reformatting as AFSP and I’ve read a couple of places that does not work.

For several days I have been reading on this Forum continuous requests for help because Time Machine no longer works. Even after the latest Mojave update to version 10.14.1, you report that Time Machine still does not work.

I'm sorry to hear these requests for help to stop running regular backups with TM!

I can assure you that, after the update to version 10.14.1, which happened perfectly, I have never had any problems with Time Machine; indeed, on today's date I have already performed n. 5 backup of my disks (one internal rotary HDD of Apple and the other external, a Crucial SSD of 1TB), backups that have always ended positively.

At this point I do not know what to think of Apple!

The question that I now ask myself is this: but why does the operating system of Mojave (I refer in particular to Time Machine) work well here in Italy, where I live, while in other parts of the world does Mojave give continuous problems?

I dare not think of two versions of Mojave that are released simultaneously ... !!

TM worked perfectly for me on all 3 systems during Beta, but in General release, one of my 3 systems has backup problems. Even after a clean install and removal of the Beta backups. No idea. I have opened a feedback bug report as AppleCare didn't care and denied that "MacOs could ever have bugs" (their words not mine) and I have also reported it up in the management levels by email.

Not good Apple.

I have the same problem on Mojave. Time machine backup failing. I've tried erasing external backup disk, replace backup disk with another one, disk utility for repairing all disks (internal and external), excluded from backup "users/shared" and still TM backup failed.

Dr_Macintosh, did you solve your problem?

TM is not working for me either.

Context:

- Brand new 6000$ MacBook Pro 15" with 2TB to backup, came with Mojave 10.14.1.

- TimeMachine backup is on a networked MacMini file server, volume is Journaled but not Case sensitive.

- I migrated my data and app from my previous MacBook Pro 2016 15" running Sierra (10.12)

- I never had App Cleaner installed

It copies 2-3GB then stop. I have 1.9TB to backup. This is unacceptable.

I can't format my network disk to make it Case sensitive, it has many other TimeMachines backups from other Macs of the family (all other working, but not all on Mojave), or legacy backups.

APPLE, DO SOMETHING.

I installed App Cleaner Pro as a trial a little while ago. I decided, however, that I did not need it at that time and uninstalled it (using its free near-double, AppCleaner.app, to do so). I have now used 'Find Ant File', an application that searches for and finds everything on one's hard drive, even invisibles, to find anything whose name contains 'App Cleaner Pro'. It found one or two left-over items, and I have deleted those, too. But Time Machine still does not work.

10.14.2

Still the same problem. Nothing has been done.

200Gb disk saved to a 1Tb external drive: not enough space.

As always, the TimeMachine image grows, grows, grows, and fills everything.

Can't believe that for months now, Apple users are left without their backup solution.

(No, I don't have the Mac Cleaning utility, never had)

Since I installed Mojave, Time machine is stuck.

Tried everything written here, but nothing works...

APPLE: instead of offering new softwares every 6 months, please take care of your customers and solve this problem !

Here's what I (since the update) have:

It stays this way (several mbs of ... and 100% CPU backupd) until the forced poweroff: finally all disk IO operations and programs using them hang and the disks (all of them) don't umount so the system can't shutdown gracefully.

By the way: external drive goes to sleep while the local struggles (it's audible) -- with that hung IO thread perhaps?

Good question. Unfortunately, finger pointing is almost to be expected when there are multiple vendors involved. It's the easy way out.

Frankly, I don't think it'll get any attention unless a major website picks it up or someone gets the attention of an Apple exec on Twitter. It looks like people have been reporting similar symptoms with Time Machine back to High Sierra.

I retired a drive and RMA'd a drive due to this issue. Maybe someone will take action based on how many hard drives have been needlessly discarded under the assumption that the drives are failing.

My Time Machine drive was previously formatted as Mac OS Extended (Journaled). I didn't try APFS on it.

This sounds promising. I am backing up to an external drive that I have partitioned. I use Carbon Copy Cloner to back up my Mac to half the external drive (partly because of 'belts and braces', partly because a CCC-backup can be used as a startup disk in an emergency and partly because it is so much quicker than Time Machine. But I use Time Machine to back up to the other half of the drive.

Both partitions are at present 'Mac OS Extended (Journaled)' formatted. Should I now reformat the Time Machine partition to APFS? Or to case-sensitive? What do the 'Discussions' pundits advise?

I know how to do the former (reformat to APFS) with Disk Utility. But if the consensus advises 'case-sensitive', please could someone tell me how to reformat to 'case-sensitive'?

For me it looks very much like a temporary folder thing.

TM is adding stuff to a temp folder and constantly thinks that this has to be backup, too?

Nobody has found out which folder to exclude yet?

Isn't there any chance to find out where TM is writing to?
