After firmware update - Time Machine Backup cannot be found

I’ve just discovered that my MAC has not done any TM backups since Jan 11th 2022.

By coincidence - my MyCloud device had an auto firmware update on the same day.

This is more than just coincidence in my view as my backups have worked fine
I now have the following error messages when trying to execute a TM backup:

  • Backup file on MyCloud local says “Zero KB of 2.91 TB available”
  • The backup disk could not be found. Make sure disk is connected or select different disk"

When I connect to the MyCloud server via MAC Finder and select the TimeMachine backup file - I get the error “You do not have permission to access this server”.

However I am able to access all other folders on the server - for example backups of photos from mobile phone.

Has anyone else reported this or had a similar problem?
Does anyone know the fix to the above?

PS: I’m in the UK - when calling the WD contact us support helpdesk number and all I get is “sorry the system is busy”…?

Maybe they are useful for you. My backups are still not working.

There seems to be nearly countless bugs in TM for Monterey and Apple will eventually get to most of them which is not to say WD can do no wrong, but all this started with Apple getting rid of AFP which ironically is something Apple mandated then deprecated for TM. There are long threads in many forums on this problem, among them is this one:

it looks like that’s yet another TM bug in Monterey. :frowning:

I’ve heard of that, too. Strangley it started for me on the day WD released their new software cutting support for afp. So either WD did not implement smb correctly or Apple did it in Monterey.

After further diagnostics and locating TM backup folder on mycloud drive - trying to access folder returned message saying file no longer exists which is baffling. I’m running an old iMac with OS High Sierra 10.13


I’ve got the same problem too.

MacOS v10.14.6 and I’ve been unable to backup since the latest WD update.

This is outrageous… i cannot backup since 17th, shortly after receiving an email from WD telling me I will have to use another link to connect online… link doesnt work:
Cherry on the cake: Time Machine doesnt find the disk anymore, even if I see it in my Network, and also all the previous backups. can someone hit me when we find an answer?
hopefully i will not face big issues with my mac by then, otherwise, i have no backup. will buy an additional disk, just in case if… thanks WD! great job

Ok the answer is here:How To Map a My Cloud or NAS Device on macOS
you have to reconnect the driver to your network if it is on wifi:
-open finder,
-in the menu: Go>Connect to Server
-enter the SAMBA connection: smb://MyCloud-XXXXXX.local
-select Guest,
-Mount on the folder you want: timemachine backup

Am connected via ethernet
Have already done as you suggest - reconnect via SMB
Still does not connect


you use a MycloudHome connected to your wifi router?


can you describe what you see when you enter the smb://MyCloud-XXXXXX.local

Raised a support ticket and got a response.

What appears to have fixed my system was going back to initial setup instructions and “important” information like ensuring the TM share had “web access” turned off, ensuing TMbackup share size was set at 100%, only one user having access to share, I chose “admin”, reconnecting to share using registered user.

Thanks, Dave

I re-adjusted various settings on mycloud device based on this feedback from WD tech support - and have got my system working again. Key changes made are indicated in my earlier response.


Thank you for contacting Western Digital Customer Service and Support. My name is Constantine B…

I understand that you are having issues regarding your backing up to Time Machine.

Can you turn off File Sharing & re-enabled i?

On the Mac/TM server machine, disabling File Sharing, (waiting 10 seconds) & re-enabling, allowed the Mac to complete the TM setup process successfully without error 13.

Hi carsondave,

seems you have a My Cloud device not a My Cloud Home. There is no setting like share size xx%, … in My Cloud Home settings. Or am I not seeing something?

Yes - I have a basic My Cloud device - apologies if I gave a different impression or used wrong terminology.

Always great to hear that people solve their problems, really.

It’s just the wrong forum. :wink:

Sorry @JoeTaxpayer but you are in the wrong subforum. This is about the My Cloud Home not the EX2.
