Yeah - but I've always been paranoid about /dev and /proc coz I don't 100% understand the effect of copying them and restoring them as files (or does cpio handle them automatically?) My file backup procedures always ignore /tmp /dev & /proc Maybe one day I should read up and understand it properly :-) As for the dd command - on a system where you want to 'ghost' a hard drive (for backup or duplication) dd is very easy I guess it should work if the restore disk is larger also - but then of course you will have unused space to configure with e.g. fdisk, or expand into with something like parted (depends on the partition ording and where swap is - but you can usually solve that pretty easily) Though - of course - you should only do it to a disk that does not have ANY partitions mounted My version of this is to put the drive into another computer - I like at least 1 removable rack in most of my computers :-) Or you can do it with a 'complete linux on a floppy' or using the recovery process or a linux on CD i.e. boot off anything but the hard drive you want to ghost and ensure you can unmount any partitions that are on that hard drive -- -Cheers -Andrew MS ... if only he hadn't been hang gliding! -- Shrike-list mailing list Shrike-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/shrike-list
