How does it work nonstop?

Using two identical PCs and a fast network between them we can connect two systems together that will tightly reinforce each other. Each system protects the data for the other.

These techniques are very new but early results are very promising.

Listed below are the techniques that already work -

1. Replicated command line interface
   Every keyboard entry is entered in both systems.
   
   
2. Nonstop file updates
   Data is written to a remote file before being committed to a local file. Individual records are locked on both systems and collisions are handled correctly.
   
   
3. Nonstop threads
   A thread that contains important data replicates itself in the backup process. If the primary thread dies, before it was able to complete, the backup thread is started.
   
   
4. Nonstop upgrades
   Before a process is replaced all the other running processes are informed. Any threads that wish to connect to the stopped process are queued until the process is restored. Therefore the running application does not notice that the process has been upgraded. In reality a process replacement is performed so quickly that it appears instantaneous.
