I added another backup option for Sesame 2.0's sesame.ini file:

BACKUP ON INTERVAL: n

where n is an interval specified in seconds. This option copies the application files running in a Sesame server every n seconds, if those files have been changed since the last time a backup was performed. This option only works in client/server mode, and only if the server is showing the server status window (so it will not run if the -daemon option is set). It goes with the BACKUP ON SAVE and the BACKUP ON LOAD options. Like the other options, this option will create a directory with the same name as the application file sans extension, and creates uniquely named backup files using the application filename with the time in seconds since 1970 appended to the filename, so that it won't overwrite the last backup.
