Impossible to install on Debian buster with its MariaDB version 10.3

MySQL & MariaDB Percona XtraBackup
1

Hello! Thank you for the backup tools!

Debian buster comes with MariaDB 10.3. Percona XtraBackup for buster are versions 2.4 and 8.0.
None of them are compatible with MariaDB 10.3.

Please advise. I’m a Debian user.

What happens when you try PXB on your Maria setup? Errors? What are they?

Ah yes. I initially thought it was a MariaDB issue but didn’t want to jump to that conclusion. Yes, MariaDB is a fork of MySQL and they have their own ways of doing things that are not 100% compatible with Community/Percona.

It turns out MariaDB forked Percona XtraBackup!

In my case it needed 2 extra switches.
