You can copy normal or compre ssed images to Flash memory. You
can produce a compressed system image on any UNIX platform using
the compress command. Refer to your UNIX platform's documen-
tation for the exact usage of the compress command.
This example shows how to copy a system image named IJ09140Z
into the current Flash configuration:
Router# copy tftp flash
IP address or name of remote host [255.255.255.255]? server1
Name of tftp filename to copy into flash []? IJ09140Z
copy IJ09140Z from 131.131.101.101 into flash memory? [confirm]
xxxxxxxx bytes available for writing w ith out erasure.
erase flash before writing? [confirm]

The series of pound signs #) indicates that each Flash device is being
cleared and initialized—one per device. Different platforms use differ-
ent methods to indicate that Flash is clearing.
The exclamation point (!) indicates that the copy process is taking
place. Each exclamation point !) indicates that ten packets have been
transferred successfully.
The series of V characters indicates that a checksum is being calcu-
lated.
An O indicates an out-of-order p acket.
A period (.) indicates a timeout. The last line in the sample configu-
ration indicates that the copy is successful.
Copy Configuration Files from a Network Server to the Router
You can copy configuration file s from a TFTP server to the router.
You might use this process to restore a configuration file to the router
if you have backed up the file to a server. If you replace a router and
want to use the configuration file that you created for the original, you
can restore that file instead of recreating it . You can also use this pro
