Can Sesame deal with the plug getting pulled while it is up and running?

For the most part - yes. The only time this might be a problem is when Sesame is actively writing to the database file. Sesame is not constantly connected to the file on the hard drive, and is thus less likely to suffer from file corruption during a power outage. Because Sesame does "lock" the database file during use, the file may have to be "unlocked" after a power outage. Sesame provides a utility for this purpose under the Server Administration tools. There is also an included standalone command line utility for this purpose, called "Sunlock".
