DESCRIPTION
dump. bsd and rdump copy to the backup device any files
within file system that have been changed after a certain date.
rdump allows use of a remotely connected backup device (see the
-f flag option). The key specifies the date and other options about
the dump and consists of characters from the set
0123456789bcfusdFwWn.
FLAG OPTIONS
The - T flag option indicates the file-system type, such as 4 . 2 or
5.2. If this option is not used, dump. bsd attempts to determine
the file-system type.

If more than one key is used that requires an associated argument,
then the arguments must be supplied in the same order as each
key.
The following options may be used for the value of key :
0-9 Set the "dump level" to the one-digit value specified. All
files modified since the last date stored in the file
/etc/dumpdates for the specified file system at lesser
levels are dumped. If a date is not determined by the level,
the beginning of time is assumed; thus the flag option 0
causes the entire file system to be dumped.

c
Use the associated argument as the blocking-factor for the
records of the backup device, rather than the default
blocking-factor of 1. This option should only be used with
the raw versions of device files. The letters b, k, m, or f
may be used at the end of the associated argument to indicate
a number of blocks, kilobytes, megabytes, or feet,
respectively.
Set the values for flag options band s to those appropriate
for the Apple® Tape Backup 40SC, including a default size
of 37.5 MB and a blocking-factor of 8K. If a value is also
