Backing up to QNAP NAS

[bdleo]

Hello All,

I am trying to configure Veeam on RHEL 6 and i get the following error when trying to backup to a windows share folder.

I have proper network access to the share, veeam is able to create a folder with a job name but it fails to create the backup.

I have tried uninstalling and reinstalling Veeam and Veeamsnap and updating the necessary dependencies.

thanks in advance

What is the output if you do modprobe veeamsnap and then lsmod | grep veeam ?

Seems the installation of the kernel module failed and therefor it won't work.

[bdleo]

Code: Select all

[root@eclipsetest ~]# lsmod | grep veeam
[root@eclipsetest ~]# modprobe veeamsnap
FATAL: Module veeamsnap not found.
[root@eclipsetest ~]#

I figured that the modprobe module was missing, when i navigate to /etc/modprobe.d
i can not find 10-unsupported-modules.conf How can i install modprobe?

Hi,

The Veeamsnap module seems not to be installed... Could you try to install the solution again following the instructions here: https://www.veeam.com/blog/veeam-backup ... lable.html

Is it possible that you installed the veeam-...rpm package and not the veeamsnap-...rpm package which should have been done first?

Thanks
Mike

[bdleo]

Fixed the issue.

After uninstalling veeam and veeamsnap, i re-installed kernel-devel and then was able to successfully install veemsnap.

Thanks!

[Mike Resseler]

Interesting...

So you actually had installed Veeamsnap first. But to get it fixed, you needed to reinstall kernel-devel... Where there are other packages that didn't work? I wonder if it was Veeam that did something wrong the first time you installed or it was already in a bad shape before that...

thanks for coming back to us with the solution!

Since kernel-devel is needed to compile kernel modules I suspect that the kernel module could not be compiled properly during the first attempt due to some problems with the kernel-devel package (wrong version for example) that is why reinstallation did the trick.
