Choosing the installation mode

If you've prepared your system for the backup, you can proceed with the installation. You must install the Tar-LVM tools on each host separately and there are two installation modes denoted as all and one.

The all mode must be used on the machine or host where the tar-lvm-all script is invoked. That's either the machine to which the backup device is connected if it is accessed directly (i.e. not via SSH) or the host which triggers the network backup centrally for a set or subset of hosts via tar-lvm-all.

Using the one installation mode is sufficient on all other physical or virtual hosts that are backing up via SSH and on the KVM virtual machines with direct access to the backup device connected to the physical machine.

Information to both modes

The installation script installs the binaries into the /usr/local/sbin directory, configuration files into /usr/local/etc, documentation into /usr/local/share/doc and creates the required directory structure under /var/local. Whereas older versions of the binaries are always overwritten, the original configuration files are kept untouched and the installed configuration files get the .new suffix if the corresponding configuration files already exist.

Keep the installation archive just for case of future uninstallation. The install.sh script itself contains the list of files and directories to install or uninstall for the Tar-LVM suite of certain version.

Installation of the whole suite - the all mode

The installation procedure is very simple. It's sufficient to download and extract the Tar-LVM installation archive and then run the included script install.sh.

To install the whole suite, pass the all argument to the installation script.

Installation for a single host or machine - the one mode

To install just the scripts for a single host or machine, pass the one argument to the installation script.
