backup error message

[Mark Colgan]

Plesk sends me something like this every full server backup:

Backup task finished.

Task was created by with guid (F5D262B4-B241-4C55-9217-21A2D1157D03)


Creation date is: 2010-Sep-11 02:00:00
Task status is: warnings

Dump full name is: backup_info_1009110200.xml


With this migration.result file attached:

<?xml version="1.0" encoding="utf-8"?>
<execution-result status="warnings">
<object name="backup" type="backupowner">
<message code="ArgumentException" severity="error">Version string portion was too short or too

long.</message>
</object>
</execution-result>


It still produces a backup file which I can download:


I googled this problem and found:

It said:
Resolution
To fix it use attached file psa9dumpagent.dll should be placed instead of the original file at '%plesk_bin%'.


I couldn't find the said file anywhere on the server so couldn't replace it


Can anyone help please
