41 This should normally only be done while the server is not running.
43 If the server is running then it may hang while the undump completes.
46 Perform database recovery at startup.
47 The server should not be running if this option is used.

50 Recompute aliases without dumping or undumping the databases.

72 This program might be used for a number of purposes:
75 Taking a backup of the non-regeneratable parts of DisOrder's databases.
78 Indoctrinating one DisOrder server with the preference values of
81 The output file is versioned, so versions produced from a future
82 version of DisOrder may be rejected by \fB\-\-undump\fR.
83 It has an end marker so truncated inputs will also be rejected.
85 The input or output file must be a regular file, as it may be rewound
86 and re-read or re-written multiple times.
88 The dump or undump operation is carried out inside a single
89 transaction, so it should seem atomic from the point of view of
90 anything else accessing the databases.
92 The server performs normal database recovery on startup.
93 However if the database needs normal recovery before an undump can succeed and
94 you don't want to start the server for some reason then the
96 operation is available for this purpose.
97 No other process should be accessing the database at the time.
99 DisOrder does not currently support catastrophic recovery.
101 This program requires write access to DisOrder's databases.
102 Ideally therefore it should be run as the same user as the server or as root.
