Backups via PMM are failing with `xtrabackup is not compatible with mysql version`

MySQL & MariaDB Percona XtraBackup

Hello team,

as the title states, when attempting to run backups via PMM (Version 3.6.0) i get an error:

xtrabackup version "8.0.35-35" is not compatible with mysql version "8.0.44-35.1": incompatible xtrabackup

However, this message does not come from xtrabackup as running xtrabackup --backup manually works like a charm - so i believe it comes from PMM Server. I have the latest available xtrabackup version for 8.0.

Attempting to use xtrabackup 8.4 would fail:

This version of Percona XtraBackup can only perform backups and restores against MySQL and Percona Server '8.4

Are there any workarounds that allows me to use PMM Server to schedule upgrades? Seems like a silly limitation to enforce version checks on server when xtrabackup has it’s own version checks.

I can see the version check happens in services/backup/compatibility_helpers.go file of PMM server.

I have just found a github issue from 2024 regarding same problem:

Can we get some traction on this problem?

Seems like i cannot add comments to that Jira ticket. However i did make a pull request in hope to fix this issue. At least for 8.0.x release.

It’s a shame that the GitHub issue was opened in 2024, Jira ticket since 2025 from what it seems - and yet no fix is available.
