Restoring Tar Archive

[ramesh_6]

Hi Experts,

I have a tape which contains two different tar archives

When i did a tar -tvf these are the two files i found

ugsapp/file1.db
/c7sysna2/file2.db

I created a file system of around 10 Gigs (these two files are hug) and mounted it under /restore and started extracting the archives inside /restore

i did
#cd /restore
#tar -xvf /dev/rmt/0m

this created a directory by name "ugsapp" under /restore and extracted file1 perfectly. When it went to file 2 it created a directory under / and tried extracting the files to /c7sysna2. This failed due to write error as there was not enough space in / to hold the files.

Can someone help me in solving how to get the extract back onto /restore and avoid /

the reason it did this is that the second file is archived with an absolute path.
You can use pax to recover the file and remove the leading /
man pax

Can't use tar to restore to a different directory, you can use pax though.
--
pax -irf /dev/rmt/0m # will allow interactivre rename
--
or you can use the -s switch to generate the output filename on the fly.
See man pax

here is what I use when I get tapes sent in with /var as the leading absolute path.
pax -r -s ',//*var//*,,' -f /dev/rmt/0m
This removes the /var and places any subdirectories/files directly under my cwd

So try 'PAX' instead of 'TAR'. 'PAX' will translate both tar and cpio:
cd
pax -rv -s'/^\///'
