Baidu has nothing to do with it. A foreign user mentioned that there may be two versions in conflict with each other, remembering that a version was installed by rpm and a binary file was installed once, as a result, the new version is called to the old version. I don't know if you have this problem. The solution is as follows:
Find the version installed by rpm

The Code is as follows:	Copy code
# Rpm-qa | grep percona- Percona-xtrabackup-2.0.1-446.rhel5

Uninstall old version

The Code is as follows:	Copy code
# Rpm e percona-xtrabackup-2.0.1-446.rhel5

Run the following backup again.
