[Sussex] Really Dumb dd question

[Nik Butler]

okay, so heres a question.

lets say at 2am in the morning when all the boring services and users
are not being utilised and the back is done we do the following


dd if=/dev/hda of=/dev/hdb


where /dev/hda1 is the active file system and /dev/hdb is never mounted.


Its about 5gb of data .



Im i mad or sane ?


IDE-Raid is not the answer neither is manual intervention im going to
cron this one ....


im goin to try it myself anyway but it would be a laugh to try.
