Build the Backup Manager kernel module

{note:title=Notice}You need to have loadable modules enabled as a feature in your kernel, and this is standard on all popular Linux distributions.

You can test connectivity with the following command (this may take a minute):

{code}serverbackup-setup --test-connection{code}


!test-connection.png!

{code}yum install kernel-devel{code}


!yum-kernel.png!

To attempt to build the kernel module, run the following command (this may take several minutes):

Kernel module is now installed.
Use '/etc/init.d/cdp-agent restart' to load the new driver
{code}

If there is no direct Internet connection between your Server Backup and R1Soft build server, it is still possible to compile the kernel module. In this case, this will be tree-step process. First, you will have to create tarball file with the kernel headers. When you should copy this tarball file from the server to some other computer which has Internet connection to R1Soft build server. From this computer you should upload the tarball to the R1Soft build server and wait for the compilation to finish. When it is finished, you should download binary module and copy it back to Server Backup. Start with executing the following command:

{code}serverbackup-setup --no-binary --kernel-dir /usr/src/kernels/YOUR_KERNEL_TREE
--tarball-only /tmp/kernel-headers-for-r1soft.tar.gz{code}

After running this command, you will see:

{code}serverbackup-setup --no-binary --kernel-dir /usr/src/kernels/2.6.32-279.11.1.el6.x86_64 --tarball-only /tmp/kernel-headers-for-r1soft.tar.gz

After it is complete, you will need to copy the module to /lib/modules/r1soft{code}

When the tarball ( {{.tar.gz}} ) file has been written to disk, perform the following steps:

* Copy the generated {{tar.gz}} file and paste it to a computer with Internet access.
* Go to [https://krnlbld.r1soft.com/] and upload the {{.tar.gz}} file to build a kernel module.
* After the build, you will download a kernel module.
* Copy this module and paste it to your Linux Server and the folder {{/lib/modules/r1soft.}}
* Restart the Backup Agent ({{/etc/init.d/cdp-agent restart}}).
