Bareos LVM Plugin

This filedaemon plugin uses snapshots to backup LVM volumes. The process is as follows:

• Create a snapshot of the specified volume.
• Stream snapshot to Bareos-fd.
• Return original volume name to Bareos for easier restore.
• Delete snapshot.

Backup of volumes is done sequentially so only one volume snapshot exists at the same time. By default a snapshot with 10% of the original volumes size is created.

Install

• Install bareos-filedaemon-python-plugin.
• Copy lvm_tools.py and bareos-fd-lvm.py to /usr/lib/bareos/plugins on the filedaemon host.
• Activate Plugins in your bareos-fd.conf (look for Plugin Directory directive).

Usage

Add the following to your Fileset and change the volume_group parameter:

Plugin = "python:module_path=/usr/lib/bareos/plugins:module_name=bareos-fd-lvm:volume_group=vg-data"

Note: Using a fast compression algorithm like LZO is highly recommended.
