OS X Server v.10.4.11
Now Up-to-Date v.5.3.2

The log files repeats the same error over and over:
General Database back up failed because of error -120
General Database back up failed because of error -120
General Database back up failed because of error -120
...

Under the "Utilities" tab the location says "Can't find directory. Error is -35" every time I start up the server manager. I have tried to set the location several times. The permissions on the folder are 777.
