PMM Backups fail, says latest XtraBackup 8.4.0-4 is incompatible with XtraDB cluster 8.4.5-5.1

MySQL & MariaDB Percona XtraBackup

Here is the error I get when trying to perform a backup from PMM Console:

xtrabackup version “8.4.0-4” is not compatible with mysql version “8.4.5-5.1”: incompatible xtrabackup

WTH? If I installed the latest production software, why is there an incompatibility?

HI Jay ,

Hope you are doing good !
Apologies that you are facing an error. I checked on below version for taking backup manually and it works good .

Hey @Jay_McNab,
Since running those versions manually works, as Puneet shows, this must be a bug in PMM. Please open a ticket at https://jira.percona.com/ for the PMM project. Be sure to include all output (may need to exec into docker to get logs), all versions of everything.

Thank you for the quick response. I am new to the Percona community, but I have been tasked with building out HeartCloud’s new Percona database infrastructure amd new Nginx web servers. Do I have to have a Percona support contract to post a bug? When I go to Jira and log in with my corporate Jira account, it says I can not create anything on that Jira page.

You probably need to create a new account on our JIRA as JIRAs between companies are typically not shared. You absolutely do not need a support contract to open a bug report. But if you’d like the bug escalated, then yes you would.
