Looks more like you have gzip'd the directory itself.

gzip merely does compression.

tar is the tool that combines multiple files into one archive.

You would want..

tar cf - files-to-archive | gzip >archive.tar.gz

to list them...

gunzip <archive.tar.gz | tar tf -

to untar them..

gunzip <archive.tar.gz | tar xf -

Hi Porter,

What you have suggest is very much true.

But in my case, how can i retsore the files from the archive.

When i use gzip -lt it shows

Compressed Uncompressed ratio Uncompressed Name
2051892827 2097160192 2.2% u03

Please help me, otherwise i am going to loose 52 hours of my work.

how did you create this archive?

The commands you list don't make sense to me.

c to stdout
r recursive
f force compression
v verbose

I would have expected it to recursively compress each file in /u03 in situ, but perhaps the "c" option caused it to write those files to stdout, but without any tar encoding it's just a stream of ones and zeros.

rule zero for making a backup is

"confirm the backup contains what you expected it to".

Yes Mr. Porter,

I've realized that i've done a big mistake, by not testing the backup.

I have some files under /u03 mount point like


I tried backing them up to /backup/bkup folder as

# cd /backup/bkup
# gzip -crvf /u03 >> u03.gz

Thanks for your inputs..
