Hello all,

We have developped an app that runs 24/7. It is being use remotly from 3 different sites and also from HQ (although HQ uses it only for managerial purposes and is 9 to 5). The app is VB6/SQL Server.

Everything (front, middle and data tier) is on the network. lately, we wera told that the app is now tagged critical and that we should find a way that operations of the 3 remotes sites should run at all times without any down times (except those planned for maintenance, if necessary).

We have looked into data replication and other solutions. But I'm not at all familiar with this kind of setup.

Any insight, ideas and comments are welcome.

TIA.
