#### 3.20.12.5 Dump the Database ¶

The `dump` subcommand dumps the database to the standard output in a format suitable for backup or sending over the network (a version 1.0 format).

    mailutils dbm dump file.db > file.dump

The produced file is suitable for input to the `create` (`load`) command. Among other uses, it provides an easy way to convert databases between various formats supported by Mailutils. For example this is how to convert the database file `file.db` to the GDBM database `new.db`:

    mailutils dbm dump file.db | mailutils dbm create gdbm://new.db

Both `list` and `dump` subcommands share the same set of options. In fact, they are pretty similar, except that use different defaults. The `list` subcommand is designed to produce a human-readable output, whereas the dump subcommand is oriented towards backup purposes.
