help tar please

Hi, i ve to restore file from a DAT (the save command used : tar cvf /dev/rmt0 /dataPROD04/DATA/*)

On my tar i have (tar tvf /dev/rmt0 >> liste_cartouche.log):

...
-rw-r----- 300 12 2097156096 Jun 30 23:16:42 2003 /dataPROD04/DATA/temp01.dbf
...


i would like to restore this file in /dataINFO04/DATA/ and not in /dataPROD04/DATA/
'cause it's not on the same server. And it does not work !

i've tried :

tar xvf /dev/rmt0 /dataINFO04/DATA/temp01.dbf

or

cd /dataINFO04/DATA/
tar -xvf /dev/rmt0 dataINFO04/DATA/temp01.dbf
mv /dataINFO004/DATA/dataPROD04/DATA/temp01.dbf /dataINFO04/DATA/temp01.dbf

I'm on aix 4.3.2

Thanks

You've made the mistake most people make with tar initially(me too). Always only tar relative paths(dataPROD04/.......) not absolute paths (/dataPROD04/....). Note the differnce is the leading /. If you tar -cf /dev/rmt0 /dataPROD04/*, you can only untar it to /dataPROD04/*, BUT if you tar -cf /dev/rmt0 dataPROD04/*, you can cd /tmp and then tar -xf /dev/rmt0, which will then create /tmp/dataPROD04/*.

Next time:
cd /
tar -cvf /dev/rmt0 dataPROD04/DATA/*

Until then:
-make a backup of your current file
-untar the file you want over the current one
-copy it away somewhere
-restore/copy your current file back

Or take a look at the man page for pax? There have been quite a few threads about the use of pax - try a keyword search in the unix forums. Good luck.

Thanks for your reponses.
i 'll restore on another server (i can't untar on the current, the file is in use) i'll create a symbolic link for the untar. And i'll debug my script for the backup.

Thx.
