can percona-xtrabackup-2.4.6 version be used with Oracle MySQL 5.7.24 or higher？
The xtrabackup-2.4 series works with all MySQL 5.7. You need xtrabackup-8 to work with MySQL 8.0.
On top of what @matthewb already said, just make sure to always use the latest version available for PXB. The version you mention, 2.4.6 is really old and we recommend running on a more recent version of the 2.4 series.
thanks for you reply on time
thanks for your reply on time,thanks for your advice about using he latest version available for PXB,i will do that .but now I want to make sure that according to on top of what @matthewb already said,my understanding is that percona-xtrabackup-2.4.6 is compatible with oracle mysql 5.7.24 or higher,please check if my understanding is correct,
As what I can see PXB-2.4.6 was released in February 2017
And Percona-Server 5.7.24 was released in December 2018
So it would be better to update pxb-2.4.6
