Hello, everyone. As SBrown has indicated, the engineers have been able to replicate the problem.
To work around it for now, go to “Settings | General | Mac Backups | Configure >>” and set the maximum to 100% of the drive.
Running MacOS 12.2 with FW 5.19.117 and the above mentioned TM problem (space limitation can only be set to 100% or else the share can not be found). Same problem persisted with MacOs 12.1 and FW 5.19.117 BUT I had no problems before the EX2Ultra upgrade, 5.18.117 on MacOS 12.1 worked fine for me.
Hope a solution can be found as I want to limit the space for me TM backups.
i downloaded that file but cant figure out how to install …where do i find that settings …? thanks for help!
Hi, you need to login to your NAS admin panel through browser. There you will find Settings and everything else I mentioned in my post.
thanks for the answer! i do have a “my cloud home” and i lock in on that homepage but no settings there…it is a pain in the a… sorry really frustrating…
(Sorry, why is this marked “solved”? Setting to 100% is a bandaid not a solution.)
I followed the instructions, or so I thought.
Turned file sharing off/on.
Disconnected the backup disk on time machine and went to add it back.
“The operation couldn’t be completed. (OSStatus error 22.)”
The update to OS5 has pretty much made this device, an EX2 Ultra, nearly useless. I mainly used it for Plex and Time Machine back ups. The few times I used it to transfer a large file to a friend, I can just use Google Drive. It started out with a lot of potential for an inexpensive little NAS. I’m sorry I didn’t choose Synology from the start. I trusted WD as I used their drives for decades, and hadn’t really heard of Synology when I made the purchase.
(I’ll watch this thread to see if there’s a solution. I liked having multiple backups available.)
For what it’s worth, I did just that, updated to 100%. But, I want to be able to back up more than one Mac to this EX2Ultra.

You can do that easily, I got four devices backing up on the same TimeMachine share, that’s not a problem at all … Prior to the EX2 Ultra I got a Time Capsule 2 TB from Apple and they use one backup volume for multiple devices intentionally. MacOS creates a unique sparsebundle for each device.
Prior, I was able to limit the size of each backup. Now, any one mac’s backup can fill the whole drive.
Am I missing something here? i.e. I liked that for this particular backup, a 1TB limit worked. It left me space on the drive for other backups or other use. Seems the (3) backups can now take over the whole 12TB drive and I have no option.
yeah, that´s absolutely right … and thats why I am back on the previous FW until this is fixed by WD …
I use just one limited TM share for all my backups, because I do not care which size anyone is in particular, as long as they take not more than 3 TB combined, which gives me approximately 4 to 6 months of backtrace on each device. the rest of the drive is used by my plex library, resilio sync and I like to have some spare space as temporary file buffer, if I got to move something
You can re-add. In MyCloud dashboard, set TMB to one share only (admin), turn web access OFF, max share size to 100%, be sure to LOGOUT. Then Mac TimeMachine sysprefs will find TMB and backup to it.
TC worked beautifully. Until it didn’t and Apple said it’s a dinosaur, say goodbye.
mine is still working beautifully in the office, … no problems there
My Cloud2EXUltra runs on 5.19.117 and I’m using the default TimeMachineBackupshare.
How do I solve this for MacOS 10.11.6.
I tried to open a support case but some how that failed. I found no way to upload the service logs and my message ended up on this page.
Please note that English is NOT my first language, and not all directiones on the page just are clear to me.
Here is what I did after WD sent me instructions which did solve the problem.
-
UPGRADED MY FIRMWARE to 5.19.XXX (latest)
-
DID A “SYSTEM ONLY RESET” using the EX2 ULTRA local DASHBOARD (under settings). Make sure it is a system only reset (if you choose system recovery, it will warn you that if you continue, you will lose all data to include shares, etc.). If you can do a backup of your server, that is best - if you cannot, proceed with caution and ENSURE you are doing a SYSTEM ONLY RESET.
-
TURN OFF MY CLOUD UNDER “CLOUD ACCESS” (NOT BY INDIVIDUAL SHARE, BUT COMPLETELY) to do your first backup after the reset. Why? It will take forever to do it with cloud service turned-on. After the initial backup after the reset, it does not matter whether CLOUD SERVCE is on or off.
-
KEEP YOUR BROWSER OPEN UNTIL THE SERVER REBOOTS. When the server reboots, the reset window will turn into a sign in to CLOUD OS 5 window. You can choose to sign in using previous credentials. If you try to create new credentials using the former user name (email), it will tell you that you already have an account and ask you to sign-in using the old credentials. If you forgot your sign-in information, you will need to make the appropriate changes by requesting sign-in information be sent to your email.
-
MAKE SURE YOU CAN ACCESS YOUR SHARES LOCALLY. MOUNT THE TIMEMACHINEBACKUP share.
-
MAKE SURE YOU TURN ON MAC BACKUPS UNDER SETTINGS.
-
TURN ON YOUR TIME MACHINE.
-
IT WILL SHOW NO BACKUPS ARE STORED AND MAY TAKE SOME TIME TO PREPARE YOUR BACKUP. If it fails to prepare your backup, unmount the Time Machine Share on your desktop and mount it again. Then restart your backup.
Hopefully that will help someone - I spent a week trying to figure this out and this was the only workaround that gave me full server functionality - both cloud and backups. And oh…yes…the Time Machine has to be set up to 100% on your EX2 Dashboard or subsequent backups will fail. If you only need occasional backups, then simply turn off Automatic Backups (do manual backups).
NOTE: I have not tested to see if I can reduce the space allotted to TimeMAchineBackups and still have functionality. I only need to backup once a month – so I do it manually – no danger that I will run out of space any time soon. I am just glad to have this thing working: as soon as I recover from all the time spent trying to figure this out, I may move the slider and see what happens. For now, I am just happy to get things working again.

Please mr @SBrown. As you see in my messages here in this string I just can’t figure out how to upload the screenshots and the system log you ask for,
not on the page Warranty Services
and not on the page International Phone Numbers | Western Digital.
So will you please, please be so kind as to tell me what page and what button I should hit, because I just can’t find it.
Jeez, I may be an absolute moron, but just helping me can’t be so hard. And pleasee note that English is not my first language, so small details may escape my understanding.
Today my device upgrade to 5.20.xxx with the same results as on 5.19.xxx: When I reduce the amount of diskspace for the TM-Share, the volume can no longer be found

@Holf and @HarrieR - just in case you are wondering about a possibility to keep time machine and limit the size - I’ve posted the guide here Temporary solution to TimeMachine Backup issues (fails after the first backup)

Thanks Andrew, for all the work you did, but this is way bejond my limited understanding of computers.
At the moment I’m working at a different solution.
Since I found in “My WD” on the manufacturers site that my warantee is valid for another 22 months, I think I just let them should solve this problem for me. They caused it in the first place, didn’t they?
From the first contacts with them I got the very welcome impression that they are perfectly willing to honor that obligation, so hope flares and I keep my fingers crossed.
