Probably not the first user with this problem, but i couldn’t find a solution so i give it a shot over here.
I’ve got a MyCloudEX4100 with Firmware 5.22.113.
Sharing works fine, i could copy lots of data to the desired designations.
But then comes TimeMachine.
I can see the TimeMachine share in macos (12.4). When i click on the folder in the finder a window is opening but changing instantly to an error message that the folder can’t be found.
Once i managed to make a complete TimeMachine backup - but when i try to make another backup the volume can’t be found.
When I try to setup TimeMachine on my MacBook it is not possible, as the guest credentials are not acceptet. On my main Mac I also used the guest credentials for the initial backup - but a second one is not possible.
Constantly i get this error message on the MyCloud device:
CIFS: Authentication for user [GUEST] has FAILED.
Only one user (me) tries do do stuff with the MyCloud device and the EX4100 is notconfigured to be used outside of the home network.
Does anyone got an idea on how to get rid of this behaviour in order to be able to use the EX4100 as a TimeMachine target?
Not only, also several issues found.
This major bug was observed in several versions before too. The issue related to size limit - I didn’t checked protocol by sniffer but seems this is issue from size limit reported not correctly.
afp protocol was WA for backups but WD has no longer support it. It looks like somehow WD shoots himself in the foot.
