Not surprisingly, I agree with Mousee.
Redundancy done right costs more than twice as much, if you count the replication that has to go on between sites.
If you need two-site redundancy, you should either find a vendor that provides this or you should do what everyone else does, which is go with another company altogether. The latter is better anyway because it provides you with backup for the contingency of any business interruption by your first hosting company.
My assessment is that the people who know they need business contingency plans are either not using $5.95-$10.95 a month shared hosting or are using two separate hosting companies. In my mind, your contingency plans are not satisfied by having only one hosting company no matter what that company’s contingency plans are.
