Unable to access Time Machine Backup

[RalphW]

Hi,
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:

Temporary solution to TimeMachine Backup issues (fails after the first backup)

So, you have and EX2 Ultra and, after recent updates, your TimeMachine backups stopped and now your Mac says something like “original disk can not be found” or backups once, then fails with “the backup disk is not available”. After a lot of ping-ponging with WD support I believe that I found the reason and (a working) solution to this problem. First of all, let’s check that you have the same problem as I do. Go to Settings → General → Time Machine → Configure and set the limit all the way righ…

@WDStaff identified this as a faulty firmware to be corrected with a future update (whenever this will Happen).

Best,
Ralph
