Upgraded to Sierra: TimeMachine "the network backup disk does not support the required capabilities"
I have a ReadyNAS Ultra 4 that has been working great for years. Upgrading to MacOSX Sierra
seems to have broken TimeMachine.
Model: ReadyNAS Ultra 4 [X-RAID2]
Firmware: RAIDiator 4.2.28
Just updated MacOSX to Sierra last night, now I get this from TimeMachine: "the network backup disk does not support the required capabilities"
Then I went into TimeMachine preferences, and disconnected the disk. Then tried to reselect the backup location but then got: "The server may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again." I changed the password on the ReadyNAS to force TimeMachine to prompt, and it did. . Then it sat with "Connecting...." for a very long time afterwhich it prompts:
The selected network backup disk does not support the required capabilities.
Please choose a different network backup disk.
How to fix?

So.... after rebooting the ReadyNAS after upgrading to "4.2.31" firmware, I was able to get TimeMachine to connect to the disk without any errors - and disk status shows in the TimeMachine preferences now...
Once I chose "Backup Now", it waits a long time on "Looking for backup disk...", then changes to "Preparing backup...".... fingers crossed, but it seems to be going now....
Confirmed, TimeMachine is currently backing up, so I guess I fixed the problem!
