    Error 791 error during progressive backup

    Polarpro

      Summary

      Error 791 error during progressive backup

      Product

      FileMaker Server

      Version

      13.0.4.400

      Operating system version

      Windows 2008 R2

      Description of the issue

      We are experiencing error messages on our FileMaker Server 13. For 10 days now we’ve been receiving an error 791 message that shows problems during a progressive backup:

      Error during progressive backup of "Dokumente_Main", a newer copy will be used or made. Remote container directory could not be moved from "file:/E:/FMBackupProgressiv/IncrementalBackup_2014-11-17_2345/Databases/MainDev/ Dokumente_Main" to "filewin:/E:/FMBackupProgressiv/InProgress_FMS/Databases/MainDev/". (20402)

      The event does not follow a regular pattern; in the past 8 days we experienced it between 1 and 6 times per day.

      The event seems to not interfere with scheduled backups.

      We have a whole bunch of incremental backup folders now, see attached screenshot.

      Steps to reproduce the problem

      We already made sure that the virus scan software for these directories is disabled (referring to a similar problem: http://forums.filemaker.com/posts/a283051d21)

      Expected result

      no errors

      Actual result

      errors

          Thank you for your post.

          First, turn off any anti-virus software as this can interfere with FileMaker Server.

          Since this has been happening for 10 days, do you recall what was changed 10 days ago to your system?  What activities preceded the first 791 error 10 days ago?

          To get around this, stop FileMaker Server, remove the IncrementalBackup folders, reboot the server, and restart FileMaker Server.  This should clear out any possible memory issues.

          Keep me updated with any progress.

            Dear TSGal

            Many Thanks for your advice, and sorry for the late reply.

            Yes, the anti virus software was disabled. We cannot remember having anything changed on the server. Removing the IncrementalBackup folders did not help either.

            We now switched off incremental backups and will turn them on again with a new server version to see what will happen.

            Best regards!
