Backup Central

Hi backupers!

I have migrated my backuppc from Ubuntu to CentOS but after the installation when I tried to do the first backup, the backup failed  with this message "backup failed (can't find Compress::Zlib)". I have already installed the last perl-Compress-Zlib, so I dont know wich is the problem. Any clue?

I've seen this before, but not on a current CentOS install. Is this
something old or with a mix of CPAN and rpm perl modules? I think it
really has to do with Scalar::Util, so forcing a reinstall of that
might fix it.

Thanks for answer. I tried what you told me but installing perl-Scalar-List-Utils (using yum) have conflicts with some files of the perl-4:5.10.1-119.el6_1.1.i686. In particular with
         file /usr/share/man/man3/List::Util.3pm.gz
         file /usr/share/man/man3/List::Util::XS.3pm.gz
         file /usr/share/man/man3/Scalar::Util.3pm.gz
I deleted them manualy because if you remove perl package (the whole one) backuppc web server, doesn't work. But that did not fix my problem. 


Maybe you are wondering why don't use CPAN, well I was not able to make it work correctly. When I run cpan install Scalar::Util, It does not make the "make" part during the compilation. 


I am thinking in changing CentOS version (I am using 6.2 currently). Do you know some CentOS distro with this bug repaired?

Do you use third-party yum repositories other than EPEL? If not, and
you are up to date, I don't think you should have any conflicts.
There were some issues reported recently on the Centos list but I
thought everything was good now.

Maybe you are wondering why don't use CPAN, well I was not able to make it

No, it is generally a bad idea to mix CPAN and RPM components. If you
are getting yum/rpm conflicts you should figure out where you got the
conflicting package and report it to the maintainer.

I am thinking in changing CentOS version (I am using 6.2 currently). Do you
know some CentOS distro with this bug repaired?

I have a couple of 6.2 systems with backuppc from EPEL and have not
seen any similar problems. They were probably installed as 6.1 and
updated via yum, but I don't think I updated at exactly the time perl
package conflicts were mentioned for CentOS. Try a yum update, then
a 'reinstall' of any packages where you suspect problems. Centos is
normally very, very stable, so I wouldn't give up on it yet.

I have recently installed a few BackupPC systems on CentOS 6.2-minimal. I used the following RPM's:

Works perfectly. Again, from a clean CentOS 6.2 minimal install.

If you're having problems, it is almost certainly because of other RPM's (and most likely, non-CentOS and non-EPEL RPM's) you've installed (or improperly uninstalled) before.

I have recently installed a few BackupPC systems on CentOS 6.2-minimal.  I used the following RPM's:

        wget http://download.fedora.redhat.com/pub/epel/6/x86_64/perl-Net-FTP-RetrHandle-0.2-3.el6.noarch.rpm
        yum -y localinstall perl-Net-FTP-RetrHandle-0.2-3.el6.noarch.rpm
Download BackupPC RPM for RHEL 6:
        wget http://download.fedora.redhat.com/pub/epel/6/x86_64/BackupPC-3.2.1-6.el6.x86_64.rpm
        yum localinstall BackupPC-3.2.1-6.el6.x86_64.rpm

It is usually safe to just add the EPEL repo to your yum configuration as described here:
http://fedoraproject.org/wiki/EPEL/FAQ#How_can_I_install_the_packages_from_the_EPEL_software_repository.3F
and then yum will sort out the dependencies itself.   The EPEL policy is to not replace/overwrite any upstream packages so it rarely causes any conflicts, but if you are concerned about that, after installing the epel-release package you can edit the /etc/yum.repos.d/epel.repo file and set enabled=0.  Then when you want something from there, add --enablerepo=epel on the yum command line when you install or update specific packages.  Most other 3rd party repos are not as careful about conflicts and are more dangerous to leave enabled for updates.

Just to add as an FYI, RPM Fusion's EPEL repository does not supply
packages that are already in Fedora's EPEL or RHEL base packages. AT
RPMS doesn't have a problem with providing duplicate packages.

Thanks a lot, boys... I tried to all solutions but reinstall CentOS minimal. I think that I could have made some mix between packages rpm and cpan. I going to follow Timothy J Massey  steps, but in a i386 arquitecture, because this is what I have (saddly).
Have anyone  ever try that kind of packages from EPEL ?

I don't have a EL box handy but I did manage to install the stock
BackupPC 3.2.1 from Fedora EPEL into a mock CentOS 6 environment.
Although it's not a full system it does have to do all of the same RPM
dependency solving and I didn't have any issues.

Have you tried from a clean slate? I'd recommend starting with a complete from-scratch install via the netinstall and the "minimal" option, get all the underlying pre-requisites setup and working properly (SSH, rsync/tar/SMB etc), focus on setting up the yum-repo config, perhaps testing that with something small and unrelated, first, and only then bringing BPC into the picture.
