    Scheduled Backups aborting with unexpected error (642)



      Scheduled Backups aborting with unexpected error (642)


      FileMaker Server

      Version (Advanced)

      Operating system version

      OS X 10.6.7

      Description of the issue

      Our scheduled daily backup has aborted on three of the past seven days, each time noting "unexpected errors."  This seemed to start just after we updated to  Security updates were also applied to OS X this time, but otherwise I can't think of any particular changes to the Server environment.

      This schedule task is set up to back up all databases to a local folder.  Both "Verify backup integrity" and "Clone the backup file" are enabled.  This is our only scheduled task.  Until a week ago, it has been running for a couple years without any problems.  There have been no changes to the task.

      In the folders of the failed backups, most files show a file size of 12kb, while a few have more realistic file sizes (our largest database is under 50mb).  In each case, the same files seem to get backed up successfully before the backup fails.  There are no files at all in the Clones folder.

      All of the files passed a consistency check.

      Steps to reproduce the problem

      Unknown.  On some days, the backup succeeds.  On other days, it fails.  In our case, it has failed as follows:

      June 3: Fail
      June 4: Fail
      June 5: Success
      June 6: Success
      June 7: Success
      June 8: Fail

      Expected result

      The scheduled backup should succeed every time it runs.

      Actual result

      Sometimes the scheduled backup fails.

      Exact text of any error message(s) that appear

      Each time the schedule is aborted, I find the following messages in the server logs:

      Server Events Error 729
      Backup aborted by user or due to error; some incomplete files may be left in destination. (20410)

      Server Events Error 642
      Schedule "Daily Database Backup" aborted; unexpected error. (20410)

          Actually, this looks like it may be a hardware issue after all.  Disk Utility is now warning that the drive is failing and must be replaced.  (The drive passed a Verify Disk test with no problems at all last week, so I thought we had ruled that out.)

          If the issue comes back after replacing the drive, I'll come back for more ideas.  Otherwise, I'm assuming that this issue is unrelated to FileMaker itself.
