transitioning packages to EPEL version

  • 772

I have previously installed backuppc 3.1.0 from centos 5 testing. The package is now not maintaned by centos anymore.

EPEL have BackupPC version 3.3.0, but yum check-update did not suggest that this package is a replacement for the backuppc package by centos

How do I transition the backuppc centos to BackupPC EPEL?

I'm not planning to perform re-installation, as this machine have a lot of configuration done to arrive at its condition now.

Any idea?

Thanks

    Problem is in the capital letters, and that's why yum thinks that BackupPC is completely different package.

    One way to achieve what you are trying to do is:

    • save all backuppc configurations/data
    • remove backuppc from your server
    • install new version from EPEL
    • restore configuration files/data
    • start BackupPC

    Configuration files (that I can see) are:

    /etc/httpd/conf.d/backuppc.conf
/etc/backuppc/config.pl
/etc/backuppc/hosts

    And data files are in directory:

    /var/lib/backuppc

    EPEL package will create config/dirs with capital letters:

    /var/lib/BackupPC

    so probably files won't get lost even if you don't backup them up.

    If you don't feel comfortable with that, you can spin a test VM with CentOS 5, install rpmbuild, and use BackupPC source RPM package, and unpack it:

    rpm2cpio BackupPC-3.3.0-2.el5.src.rpm | cpio -idv

    Then in .spec file add a line:

    Obsoletes: backuppc

    somewhere around "Require" lines. After that rebuild RPM, transfer it to your server and install it with:

    rpm -Uvh BackupPC-3.3.0-2.el5.i386.rpm

    After that, you could use updates from EPEL.

    Note: Please don't compile and build package on your production machine, spin a dev VM for that. If you are not feeling comfortable enough I can build a package for you.
