bareos_mysql_dump fails on Bareos 25

[Fabién Jardinero]

# cat /etc/os-release
NAME="openSUSE Leap"
VERSION="15.6"

# bareos-fd --version
25.0.2~pre13.add249aa9

We're considering Bareos with commercial support for our company, my head of IT requested a demo of a few options, I chose Bareos because I've worked with SUSE for a while, but I'm running into issues with the MySQL plugin.

I got this error (full verbose output, error in bold)

So I went ahead and fixed the BareosFdWrapper and BareosFdPluginBaseclass and managed to get rid of the error but then I was getting:

"AttributeError: module 'bareosfd' has no attribute 'PluginBase'"

I've tried many changes to the plugin .py files (I cannot remember how much now) and the issue is always comes back with:

"15 2025-12-23 21:24:28 File JobId 22: Because no backup data was received, no device was reserved. As such no Session Labels were written for this job."

I'm not well versed in Python (or programming at all) so I'm not really getting anywhere with trying to fix the code.
Unfortuantely I cannot use bareos-filedaemon-percona-xtrabackup-python-plugin because that works with MySQL 8.4 and I have MySQL 8.0
I can backup any other files from the same host, so the issue is not really the config but the plugin (seems to me, might be wrong).

I tried downloading an older version of Bareos but it seems that community support is only for current (I totally understand, free product= we are the testers), should I open a bug?
Any help would be greatly appreciated!

Hi Fabién

So the module you're trying to use is a community module which is supported / developed by the community. Bareos gmbH package it, that's all.

But anyway this module has a systemtest and should be tested before release (I will check if this is the case under SUSE).

What you might want to try instead perconna is the mariadb plugin which allow pitr backup/restore on mariadb and that one should work out of the box.

If you can yes, please open an issue on github, giving as much information as you can.

Regards

> Unfortuantely I cannot use bareos-filedaemon-percona-xtrabackup-python-plugin because that works with MySQL 8.4 and I have MySQL 8.0

For the right version, it seems version 8.0 can still be grabbed from perconna

https://docs.percona.com/percona-xtrabackup/8.0/

Install that version to connect the plugin with.
