Well, it seems I’ve found the problem. When I configured the share as the Time Machine backup, I set the maximum size to 4TB (down from the maximum of 9.7TB). Once I reset the maximum to 9.7TB, I got full access to the drive and am able to resume my backups. Since I don’t want the drive to fill up with Time Machine backups, I will try lowering the maximum again later, but the idea that the share can’t be accessed because I’ve set a size limit (well above my Mac’s requirements) is ridiculous.
Now that the first backup is complete (and a few since), I went back to reduce the maximum and ended up with the same problem: access to the TimeMachineBackup share is blocked.
If I allow the TimeMachineBackup share to use up to 100% of the disk, I will eventually run out of space. If I set the maximum to less than 100%, I can’t access the share after the next backup takes place.
For the record, I’m reducing the maximum by going to “Settings | General | Mac Backups | Configure >>”.
The support case is 220112-001816 and yes, I provided my system logs to the phone agent.
The good news is that the engineers have been able to reproduce the problem. Here is the answer I got earlier today:
Please be informed that we are able to reproduce the reported issue using macOS 11.2 and 12.1 with firmware 5.19.117 and 5.18.117 and will be working to resolve the issue in a future firmware release. Unfortunately, we cannot provide a specific release version or date at this time.
I have this connection: smb://MyCloudEX2Ultra._smb._tcp.local
Push the WD TimeMachine share to the limit an it will work. I tried to decrease the share after the first backup but TimeMachine fails to connect. My MyCloudEX2Ultra has FW: 5.20.113.
Enjoy live after COVID Cheers, Sam
WD removed AFP as file protocol, so ensure you‘re connected through SMB (previous post ). Once connected through SMB, you have to create a quota limited user and set Time Machine Backup limit to 100%. Description here:
@WDStaff identified this as a faulty firmware to be corrected with a future update (whenever this will Happen).
I have a My Cloud EX2 Ultra (macbook pro 2021 version 12.1) and I have the same problem since the feature was released in January 2022.
Even using the smb protocol and choosing a 100% limit, the first backup works but after that I can’t create a new backup and I can’t get into the time machine.
Also, when I try to restore the entire system (after a system reboot and using the restore utilities by pressing the power button), I can select My Cloud to restore the system but the connection fails without error. I don’t understand.
Please WD supports, can you provide a new version quickly?
