DRBD for Off-Site Disaster Recovery

on Ubuntu Hardy

Issue

A local machine (server) is to be provided with off-site disaster recovery (backup). The off-site location is accessible via the public Internet with reasonable bandwidth (100 Mbit/s).

DRBD is a distributed block level remote replication solution. Initially it was designed for machines sitting side by site with a dedicated network link between them. It does work well for remote setups like this one here as well, given proper tuning.

OpenVPN is 'the standard' VPN system for Linux it provides compressed VPN connections with minimal setup requirements.
