I'm not sure why you attached your comment to this message, as it doesn't seem to me a good way of doing the task that you want to do.

What's in partition 1? It has to be an extended partition to contain partitions 5 upwards. Personally, in the absence of another OS, I'd have hdc1 swap hdc2 / hdc3 /usr hdc4 /foo (which contains /foo/var /foo/tmp and /foo/home) or you might have, say, hdc1 swap hdc2 / hdc3 /usr hdc4 extended containing: hdc5 /var hdc6 /tmp hdc7 /home but you have to choose your own scheme according to your prejudices. I now use a 50--60MB / partition where the biggies are split off. Now let's do the copying. First the root partition. Assume it's going to be on hdc2, as in all the examples above. mount /dev/hdc2 /mnt cd / find -xdev | cpio -damp /mnt umount /mnt That copies everything in your present / partition into the new one, but only the files within the partition, not any directory trees like /usr that have been mounted separately. To do another partition, like /usr : mount /dev/hdc3 /mnt cd /usr find -xdev | cpio -damp /mnt umount /mnt and the same thing for other partitions. At the end, you need to check your new /etc/fstab with mount /dev/hdc2 /mnt edit /mnt/etc/fstab and ditto for lilo. If you're going to (a) boot from a floppy and (b) remove the old disk or swap the IDE cables round, then there's no need to change a<->c as you'll always be booting into hda. You only need to correct any changed partition numbers. When you boot the new disk from a floppy, check the /etc/lilo.conf and rerun lilo. Then see if it boots correctly. If you have problems understanding this, do post your existing partioning scheme (/etc/fstab will do nicely) and your intended one. If you're splitting or merging partitons, you have to do certain things slightly differently, and I can hardly post every detail of every instance.

I do not know that bug, and I am not aware of any, as I am using tar this way very often. I have never lost a file. Permissions, time stamps, everything stays as it was. Maybe it refers to older versions of tar. Very old ones for instance did not handle very gracefully certain special files. It is possible that tar is confused by the /proc file system.

As this is done just in a pipe, I would not loose the time to compress and uncompress. BTW, this also handles correctly special files like those in /dev directory. All permissions will be preserved.

Copying a partition, was Re: ** Emegancy Request **
Quoting Bill ([EMAIL PROTECTED]): > Can someone please tell me the easiest and safest way to mirror > a Hard Drive, keeping all permissions, owner, groups etc. intact Well I wouldn't call "man dd" a safe way of doing this unless you mean you want to make a bit for bit copy of the disk. If that's the case, then you don't need to worry about permissions, owner, groups etc. because it's not even going to worry about what sort of partitions or filesystems you have. I've never done it though; you're on your own. But I'll assume that you really want to copy the contents of a partition from one disk to another. If that's so, then: mke2fs /dev/new-partition which will create the lost+found directory of the correct size mount /dev/new-partition /mnt cd to the top (mount point) of the old partition (which might be /) find -xdev | cpio -damp /mnt That will copy everything in that partition, correctly. What will differ: Directories will have new timestamps and they will be just big enough for the files contained therein (the old ones may have contained more files at one time). What still needs doing: You may need to adjust /etc/fstab if the changes you make result in different device names. If this was a root (/) partition and you use lilo, you will need to boot to it (with a floppy, say) and run lilo. I'm told you can avoid booting by using chroot or lilo -r but I haven't actually done this.

From above it sounds like you want to mirror the files, etc (ie. without regard for partitions, etc, on the disk). If so, have a look at GNU tar. The man page documents options for preserving file attributes. I've done lots of backups with GNU tar and had no problems restoring files with the correct attributes. If you're looking at mirroring the hard disk *itself*.. hmm... I'd have a look at GNU dd, but perhaps some one else on the list might have a (better?) suggestion if that's the case.
