newbie - CPIO restore problems

[Jennie Gutentag]

Hi All !

I have a problem with cpio restore options.
I want to be able to restore data to a temporary directory and not to its original location.
any attempts I did using -p options have failed ....
any ideas ? .......

any help will be highly appreciated !
Thanx,
Jennie

Hi,

In your case, the easiest tool wouldn't be cpio, but rather 'pax' which is used by ignite UX and can read tar as well as cpio archives. Th most important feature is the 's repl_string' which allows you to subsiture patterns in restore paths. I use it especially for archives created with absolute paths. You can even find examples in the man page.

Best regards,

Jean-Louis.

Hi,
I have just tried this:

# pax -rv -s'/^\///' < your_cpio_archive

and it extracts everything from your_cpio_archive and writes it to your current directory. I is perhaps also possible to use pax with the -i option for interactive mode.

Or if your archive only contains a few files and you want to stick with cpio, use the '-r' option to rename files as they are copied in.

This is unworkable for large archives, unless you like typing...

Jennie,

One quick question/suggestion.

Is the path on the tape an absolute path or relative.

If the path begins with / then its absolute and will cause you some issues.

If the path begins with a directory or filename eg tmp/ or data/ etcetera then you can cd to where you want the files restored and run the cpio command without problems.

mkdir /tmpdir
cd /tmpdir
cpio -idmu < /location/cpio.file

the p would be used if the directory already exists. Let say after you restored it to a tmp dir and you want to put in another directory
cd /tmpdir
find . -print |cpio -pdmu /another_directry

good luck
