I have recently upgraded to Bugzilla3 and I wanted to restore my bugzilla database with my backup but when I attempt to tar -xvvzf file.tgz I get the error

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error exit delayed from previous errors

My script that creates the backup is:

#!/bin/sh
datestr=`date +%m-%d-%Y`
bakdirpart="bugzilla.backup.$datestr"
bakdir="$HOME/$bakdirpart"
mkdir "$bakdir"

(cd /etc; tar cvzf $bakdir/mysql.conf.tgz mysql)
(cd /etc; tar cvzf $bakdir/apache2.conf.tgz apache2)
(cd /usr/share; tar cvzf $bakdir/bzreport.share.tgz bzreport)
(cd /usr/share; tar cvzf $bakdir/bugzilla.share.tgz bugzilla)
(cd /var/lib; tar cvzf $bakdir/mysql.hotdb.tgz mysql)
(cd /var; tar cvzf $bakdir/www.tgz www)
(cd "$HOME"; tar cvf "${bakdir}.tar" "$bakdirpart")

Is there any way to recover my backup copy?

Thanks for any assistance anyone can provide

What does "file file.tgz" return?

it returned:

code:

140:~# file bugzilla.backup.01-03-2011.tgz

Output:

bugzilla.backup.01-03-2011.tgz: POSIX tar archive (GNU)

So it's a tar archive that never got gzipped despite the name you gave it. Just untar it, don't try to ungzip it.

Thanks for the quick response Alucard

I don't know anything about tar. I reviewed the man page for tar but I can't seem to figure out what command to use that will untar a file. I tried the following

Code:
tar -Zxvf bugzilla.backup.01-03-2011

Output:
140:~# tar -Zxvf bugzilla.backup.12-03-2010.tgz
tar: compress: Cannot exec: No such file or directory
tar: Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error exit delayed from previous errors


I also tried

Code:
tar -zxvf bugzilla.backup.01-03-2011

Output:

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error exit delayed from previous errors

What am I missing?

Thanks again for your help

One remark for the readability of the script: you can use the option -C (uppercase) followed by a directoryname instead of creating the subshells. To the original problem: you used -v there: what was the output during the creation of the archive?

Again, your tar file is not compressed! So don't try to decompress it.

Try: tar xvf bugzilla.backup.12-03-2010.tgz
