I am managing a few sensitive websites, that need to be up and running 24/7 how ever I worked with many VPS and dedicated server providers over the time. The problem is that downtime is inevitable, at least for a few hours a year and my client is pinging the websites round the clock.

Is there any solution like automatic switching DNS or hosting on 2 servers from 2 different providers and is there a way for syncing the data between servers before actual sinking.

Have you considered a CDN like Amazon CloudFront or CloudFlare? – ub3rst4r Aug 1 '12 at 21:52

Use Scalr

Fault-tolerance, backups, uptime, and efficiency

Scalr provides you with a high uptime, fault-tolerant website: Scalr monitors all your servers for crashes, and replaces any that fail. It backups your data at regular intervals, and uses Amazon EBS for database storage. And to make sure you never pay more than you should, Scalr lowers costs by decommissioning servers when load subsides.
