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
