If anyone is still having issues make sure you don't have oplocks and level 2 oplocks disabled.

Time Machine would not work with the following in my config file

level2 oplocks = no                                                                   
oplocks = no   

Has anyone encountered:

Time Machine can’t connect to the backup disk. The operation couldn’t be completed. (OSStatus error 13.)

After they type their password on the time machine menu
