Google's Postini Services is a hosted continuity solution for your on-premise email server. Google promises to ensure rapid email failover in the event of a server outage with complete and constant email replication; through
Gmail. GMC is another option for the increased mobility and accessibility of critical data.
Google seems to have launced an all out attack on Microsoft's hitherto personal niche, of enterprise-hosted email services, following the increasingly successful adoption of Gmail; as the email client of choice. With a claim of ten-fold reliability over in-house hosted Microsoft exchange systems, coupled with low cost-per-head and industry leading security architecture, 'Google Message Continuity' (GMC) is a concrete step in the right direction and should soon become the ultimate M$ Exchange migration tool.
