@backup
This command will dump a flatfile of the database to the data directory. The flatfile will be named dump.<date>.tgz. IE, dump.0219-1613.tgz where 0219-1613 stands for February 19, 4:13pm.
This file is tarred and gziped. It includes the game flatfile, and the mail and comsys databases. It does not include any of the text files, the .conf files or the mux.config file. Those would need to be backed up separately.

Because PennMUSH natively dumps its databases as flatfiles, it has no @backup command.
