Hi @Daljit1 ,

Can you please test the backup with the latest 2.4 version?  
Version 2.3 is EOL and your specific version 2.3.10 is really old and might contain a lot of issues.  
If the error persists on 2.4.21 (current latest) please attach full xtrabackup log.

Thanks

Hi @Daljit1 ,

To start with, let’s try PXB 2.4.18 (the latest version we have available for Trusty).

Hello Altmann,

Hope you are doing fine!

I upgraded 2.4.18 but getting same error while backup.

We are maintaining backup on slave and I noticed backup completed if slave process not running. (slave stop)

Any idea please suggest me on it.
