I ask this as I have just had a nasty experience with 1 of these in a place where I was working & I apparently bumped a modem power cord out of its socket which has managed to apparently corrupt this database....
(Here is a little info I found relating to them on a forum on stack overflow - The FileMaker Server service "prefers" being stopped using the Admin Console (though the Admin Console may sometimes be unable to stop it either). If the FileMaker Server service stops any other way (including power loss, via the management console, or even a normal system shutdown) then some of your databases may become corrupt. Same if a client crashes during an operation, or if the network connection is lost suddenly. The solution for a power loss is to write a batch script to try and automate the shutdown, and then buy a UPS and program it to execute your script before the juice runs out. And hope it works. Otherwise backup hourly using the built-in scheduler. Aside: SQL server doesn't have this problem because it can roll back uncommitted transactions.)
