Unix Tip #4522- July 29, 2025
DUMP TO A FILE
Ever have the need to dump the contents of a partition
into a single file on a remote machine. The local
machine does need to be trusted by the remote machine
for this to work.
Use the following command:
# dump 0fb - 126 [filesystem] | rsh [remote machine]
'(cd [destination dir];dd of=[destination file] os=126b)'
# dump 0fb - 126 /dev/root | rsh foo '(cd /usr2/tmp;dd of=root.dump os=126b)'
NOTE: All tips provided are USE AT YOUR OWN RISK. Tips are submitted

test each tip in a non-volitile environment before placing into
production.
