In Solaris, I would: - Make hardware probing commands as restricted as possible (like drvconfig, devfsadm or prtdiag) - recreate the disk/slice/volume special files. - Mount the filesystems and perform the backup. - remove the disk/slice/volume special files. I really don´t know the exact commands to perform this on Linux, but I´m quite sure thats prossible. In solaris I could go way further, like erasing/recreating scsi controller definitions (sd.conf).

I want make a disk to disk backup, for example with dd utility dd if=/dev/hda of=/dev/hdb bs=1k conv=sync,noerror but I want that this disk can't mounting by anyone. Is this method to make disk to disk backup correct? It have any problem? I don't like that a possible hacker can mount disk device and get information from the backup disk. The system has installed LIDS on the primary disk, but backup disk (secondary) is not affected. Can anyone help me about how to hide the secondary disk to can't mount?
