copying file systems ...

[Jamie Risk]

How do I copy an entire file system, symlinks and all, to a temporarily
mounted partition? (what are the pertinent 'cp' switches?)

I've got an extra harddrive (&PC) and I want to mirror my original system
with as little work as possible.

I put the third harddrive in my system, and mounted it at "/mnt/new". Thus,
the mounts are:

/dev/hda2   /         ext2
/dev/hda1   /boot     ext2
/dev/hda3   /usr      ext3
/dev/hda4   /home     ext3
/dev/hdb1   /usr/doc  ext2
/dev/hdb2   /usr/src  ext2
/dev/hdc1   /mnt/new  ext2

Can I simply use the following command?

[bash-2.05]# cp -r / /mnt/new

p.s. (I'd then test the output using 'chroot')

I use cp for backups as "cp -av /dir1/ /mnt/backup", etc. Just skip /proc <g>

I use this little thing I call tartar.  Note that it will copy all of a
partition if you ask it, but won't copy all of a multi-partition VFS.

mkdir /mnt/new/boot
tartar /boot /mnt/new/boot

and so on.
