Does Percona Xtrabackup support RedHat release 4 I downloaded Percona's Xtrabackup rpm file for RedHAT. I attempted to install but hit into an error. The error seems to point to missing dependencies and libraries. I have no issue with RedHat 6 OS. I could not find the binaries in Percona's website for RedHat4. 

Is it supported in RedHat 4? Possible for a workaround?

rpm -Uvh percona-xtrabackup-2.2.9-5067.el6.x86_64.rpm

Percona XtraBackup 2.2 does not seem to have support out of the box for Red Hat 4:


  Supported Releases
  
  The CentOS repositories should work well with Red Hat Enterprise Linux
  too, provided that yum is installed on the server.

CentOS 5 and RHEL 5
CentOS 6 and RHEL 6
CentOS 7 and RHEL 7
Amazon Linux AMI (works the same as CentOS 5)



Try, however, first the generic Linux binary and see if you can at least run the xtrabackup binary.

If not, you can either try to compile it by yourself (it shouldn't be too difficult in terms of dependencies, but Xtrabackup is a monster source and you may en up in dependency hell) or hire their paying support/development so they can make it work for you (they have great engineers).
