Timemachine stops working after update to FW 5.19.117

Maybe yes but I have a strange feeling that I’m banging my head against the wall when it comes to support )

I mean they are fast to replace your device if it’s broken but firmware support is somehow… slow.

Replacing my machine wouldn’t do any good, because the new device would still run on the same faulty firmware.

One more with same problem here. Thanks to this thread, the workaround of set the limit to max (100%) worked for me. Hope WD fix this soon, as I don’t want to use the entire disk just for TimeMachine backups.

Do you know is this is still relevant with the new 5.20.113 update last night? I still get he same error message on Time Machine

The steps I outlined continued to work [FOR ME] after Firmware update 5.20.113, but only AFTER I restarted my WD EX2 Ultra and mounted the TimeMachineBackup share. For whatever reason, my Time Machine showed no older backups were present after Firmware update 5.20.113; however, after I completed a backup on the same day you emailed me (10 Feb 2022), all looks normal again (see below: it shows the oldest backup from last year as well as today’s backup). If I did not answer your question, pls rephrase it and I will try to answer it again. My Time Machine is working at this time.

Are you sure it is SYSTEM ONLY “RESET” and not Restore to default? I can’t see a a reset option in settings Dashboard

If you click on System Setting, Utilities you should see this. At the VERY BOTTOM, where it says RESTORE TO DEFAULT it gives you several option for which kind of RESTORE you want.

The DEFAULT RESTORE TO DEFAULT OPTION you want is System only. That should be the “preselected” tab. See below:

There are multiple RESTORE TO DEFAULT OPTIONS (System Only, Quick Restore, Full Restore):

Again – be sure to effect a Restore to Default - System Only. Once you choose System Only and click Restore you get this final warning to let you know that only system files will be replaced – DATA FILES SHOULD REMAIN INTACT.

I recommend a server backup if feasible because machines have a mind of their own. I DID NOT do a backup and it worked as it should [FOR ME]; all of that said, I cannot predict the final outcome for your specific NAS.

Thanks for asking.

All seems to be working, back up is now possible and its just started - cheers

Glad you got it working…

Time machine stopped working on MyCloud Home device around this same time (January 17th). I have tried everything suggested by WD. Spent an hour on the phone with an Apple TM specialist, who said it appeared to be a WD problem. Cranked up an old Time Capsule, and TM works fine there. Spent an hour on the phone with a WD specialist who said to upgrade to Monterey. STILL NOT WORKING. Time Machine just dies with no explanation, and even worse – I can’t find the old backups on the device. Clearly the firmware upgrades broke something!!! How about a fix that involves putting the old firmware back!!!

Dear WD Community, @WDStaff and @SBrown,

I contacted @WDsupport and specifically asked when the issue discussed here and acknowledged by @WDSupport will be resolved. In essence, the answer was:

‘We identified the issue and are in the position to reproduce it. Accordingly, it does not make sense to open a support case. We will fix it with a future firmware update and publish the update on our website once it’ll be ready.’

For the time being, it seems as if the workaround (setting the TimeMachine limit to 100%) will have to serve as temporary ‘solution’.

I got a similar message by phone, so hopefully they’ll fix it soon. @WDStaff

@SBrown, thank you for your work trying to solve this issue!
Like @RalphW, I’m running macOS 10.12.6. And in case it matters, upgrading my macOS is not an option for me.

I’m fixed going to “Shared Files” and creating a new shared folder. In my case I named it as “TimeMachine2”. Now I’ve gone to setting > Apple backup > and selected the new shared folder. At this moment it is creating a new backup… fingers crossed
