Hi:

The answer is that it depends. You need to first do a cpio -icvt < /dev/rmt/0m to see if the files were backed up with absolute pathnames. If the pathnames begin with a / then restoring to another directory is difficult but if the cpio was made with relative paths the the above solution will work.

If absolute paths were used, let us know and there are ways to do that as well.

Hi,

Also, change the directory first and then restore the files:

# cd /home
# cpio -idumv < /dev/rmt/0m

This may help you:

If you use the GNU version of cpio (I've still made it temporary available on http://home.hccnet.nl/h.m.brand/ncpio) you can use the option --no-absolute-filenames to achieve what you want.

--no-absolute-filenames
In copy-in mode, create all files relative to the current
directory, even if they have an absolute file name in the
archive.

# cd /tmp/temp
# ncpio -iuvdm --no-absolute-filenames
Job done :)

If it is one or a few files and you can do it interactively, then you can do it by (also) specifying the "r" (rename) option:

$ ll /tmp/passwd
/tmp/passwd not found
$ echo '/etc/passwd' | cpio -o >junk.cpio
29 blocks
$ cpio -ir '/etc/passwd' Rename
/tmp/passwd
29 blocks
$ ll /tmp/passwd
-r--r--r-- 1 franks ftp_group 14319 Mar 15 14:38 /tmp/passwd
$

If it is for many files or/and non-interactively, then see pax(1). pax(1) can read (and write) cpio (and tar) archives.

Hi all,

Thanks a lot for all your help, much appreciated.
Sorry about the delay, my PC got struck by lightning and took time to fix.

Thanks once again
Chris

Maybe that was God telling you to use a UNIX W/S ;^)
