Resolved Backup Manager doesn't work after updating to 17.8.11 MU3

[Joost de Bruijn]

Yesterday my Plesk 17.8.11 installation was updated to MU3. This night I received the following error by mail:

The following error occurred during the scheduled backup process:

Runtime error: Dump validation utility returned empty result at /opt/psa/admin/bin/plesk_agent_manager line 1297.
; Dump validation utility returned empty result​

In the UI I cannot open the Backup Manager: I receive an empty error message: also the panel logging does not contain any additional information:

[2018-04-01 11:25:49.139] ERR [panel]
[2018-04-01 11:25:58.034] ERR [panel]
[2018-04-01 11:26:22.187] ERR [panel]
[2018-04-01 13:07:38.817] ERR [panel]
[2018-04-01 13:10:30.791] ERR [panel]​

I ensured the backup FTP-server is up and running and the credentials haven't changed. Also, the FTP-server software is not updated recently. The FTP-logging does not identicate something worth to mention. Is this an issue with MU3? How can I resolve it?

to nearror down the issue,
which OS are you running and is it a scheduled Backup of a Domain or a Server Backup.
is there something helpfull error message in the PMM log files, usually under /var/log/plesk/PMM/

I'm running Ubuntu 16.04.4. Thanks for the other logfile location, I was not aware of that one. Maybe this can be interesting:

This error did not occured before the upgrade to MU3.

Hello. Unfortunately, we cannot reproduce the issue. Could you please do the following steps:
1. Set FORCE_DEBUG_LOG to 1 in /usr/local/psa/admin/share/pmmcli/pmmcli-rc
2. Run the backup
3. Find the latest log file /var/log/plesk/PMM/backup..../backup.log. And post their parts from the line with 'Check dump' till the end of the log file

It's resolved after upgrading to MU4, so this issue can be closed.
