Install Backup Agent on Debian and Ubuntu manually

{toc:location=top|maxLevel=3|minLevel=3|type=flat|separator=pipe|style=border:1}

h2. Option 1 - Install the Backup Agent using APT

Configure an APT repository on Debian and Ubuntu to install the Backup Agent using apt. This repository also helps to manage upgrades of the Backup Agent in the future. For more information about upgrading the Backup Agent, see [ServerBackup:Upgrade Backup Agent for Linux].

apt-key add r1soft.asc{code}
# Run the following command:
{code}apt-get update{code}
# Once the APT repository is configured, you can use the following command to install the Backup Agent:
{code}apt-get install serverbackup-enterprise-agent{code}

h2. Option 2 - Install the Backup Agent using DPKG

h3. Download Backup Agent

For more information about downloading the Backup Agent, see [ServerBackup:Obtain Linux Backup Agent].

h3. Make sure you can unzip the download

Most Linux distributions come with the *unzip* utility pre-installed.

*To determine if you have the unzip utility*:

Run the following command:

{code}which unzip{code}

The system returns output similar to the following:

{code}which unzip
/usr/bin/unzip{code}

If it returns nothing, install the *unzip* utility first.

*To install unzip on Debian or Ubuntu*:

Execute the following command:

{code}apt-get install unzip{code}

h3. Extract the Zip file

Use the {{unzip}} command to extract the files.

{code}unzip ServerBackup-Enterprise-Agent-linux64.zip{code}

h3. Install the packages

{note:title=Notice}You must be a Linux root user to install the Backup Agent.
{note}

The archive extracted contains two folders: one with {{.deb}} packages (in our case, "*deb-linux64*") and one with {{.rpm}} packages ("*rpm-linux64*"). If you are installing on Debian or Ubuntu, choose the folder with {{.deb}} packages.

Each folder contains a set of the Backup Agent components:

* {{serverbackup-setup}}
* {{serverbackup-agent}}
* {{serverbackup-enterprise-agent}}
* {{serverbackup-async-agent-2-6}}

You must install all of the previous folders in one step. Use the {{cd}} command to go to the folder with the packages (in our case, "*cd deb-linux64*"), and then run the following command:

{code}dpkg -i *.deb{code}

h4. 1. Compiling Server Backup kernel module against kernel headers

You must compile the kernel module using the kernel headers. The program {{serverbackup-setup}} obtains all the information needed to compile a module from your running kernel.

In order for kernel module compilation to work, you should have Internet connectivity directly from the Linux server you are installing the Backup Agent on, to TCP port HTTPS (443), on the host {{krnlbld.r1soft.com}}.

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

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

h4. 2. Install kernel sources

If you are using an unmodified kernel provided by Ubuntu installer, install the kernel-devel package:
{code}apt-get install linux-headers-`uname -r`{code}
{info:title=Note}
In the recent versions of Ubuntu Server the correct version of Linux-headers is probably already installed, so you don't have to install it.
{info}

h4. 3. Build Server Backup kernel module online (direct Internet connection to R1Soft build server)

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

{code}serverbackup-setup --get-module{code}

If the module is compiled and installed successfully, the system displays output similar to the following:

{code}Saving kernel module to '/lib/modules/r1soft/hcpdriver-cki-3.2.0-29-generic.ko'
Kernel module is now installed.

# When compilation is finished, download binary module, and then copy it back to the Backup Agent machine. Start by executing the following command:
{code}serverbackup-setup --no-binary --tarball-only /tmp/kernel-headers.tar.gz{code}
After running this command, the system displays output similar to the following:
{code}Gathering kernel information
Gathering kernel information complete.
Creating kernel headers package
Checking '/tmp/r1soft-cki.1353084109' for kernel headers
Found headers in '/tmp/r1soft-cki.1353084109'
