rdump - file system dump across the network
/etc/rdump [ key [ argument ... ] filesystem ]
Rdump copies to magnetic tape all files changed after a certain date in
the filesystem. The command is identical in operation to dump(8)
except the f key should be specified and the file supplied should be of
the form machine:device.
Rdump creates a remote server, /etc/rmt, on the client machine to
access the tape device.
Same as dump(8) with a few extra related to the network.
