cpio help

Duffs — Mon, 23 May 2005 09:36:17 GMT

Hi,

I want to duplicate the home dir of a RH linux server onto another linux machine. I have scp'ed the entire dir over however this does not preserve permission or ownership rights.

I believe cpio can effectively do this however I have never used cpio before. The man pages mention how to cpio a dir to a new dir but can I alternatively use cpio to create a file that I can scp to the /home dir of my other server and import so that the entire sub dir structures will be identical and username/permissions will be in tact?

Yes that method will work and all ownerships and file modes will be preserved.

On the source box,
cd to desired starting directory
find . -print | cpio -ocv > /tmp/xxx.cpio
or
cd /
find /home -print | cpio -ocv > /tmp/xxx.cpio

Now ftp, rcp, or scp /tmp/xxx.cpio to the target machine.

On the target machine:
cd to desired starting directory:
cpio -icvdum < /tmp/xxx.cpio

Hi,

You can create a tar archive and then scp it to the other system and untar the archive over there.

Is that possible.

Hope this helps.

In that case, please just stick to scp and use the -p option

â p Preserves modification times, access times, and modes from the original file.

For cpio it would be something like

hosta# find . | cpio -ocv >/tmp/xx.cpio
hostb# cpio -iuvdma
Enjoy, Have FUN! H.Mer
