Data recovery emergency on a downed server... Help please!!
Don't use zcat to decompress a file ... use the appropriate tool, gunzip: gunzip file.tar.gz ls file.tar NB. gunzip -c file.tar.gz is identical to zcat/ He already has a backup of the tar.gz ... it's called a tape Tom Walter Dnes wrote:

*MAKE A BACKUP COPY OF THE TAR.GZ FILE FIRST* !!!
Straight from the man page...
tar -xvvzf foo.tar.gz extract gzipped foo.tar.gz
..did you remember the "z" parameter ?
I've had similar problems with tar.bz2 archives. I find that doing it one step at a time works. Note, you will need a *LOT* more diskspace.
Step 1) zcat filename.tar.gz > filename.tar The "zcat" executable is named "gzcat" in some versions. Use whichever one works on your system.
Step 2) tar -xvf filename.tar

Yep, still under OE (*shudder*) Thanks for the suggestion, Walter. I did make a copy of the tar.gz file but I got nothing useful out of it. I am still waiting now for the darn activation code for a MS-based ext3-aware data recovery tool... Maybe that will finally crack my rough luck thus far - if it ever arrives! Tom, thanks for the note about gunzip -c being the same as zcat. I will make another backup and give that a go, though my hopes are narrow... Oh, and given the current state of my hardware; I certainly would not trust my tape to make another dump so Walter's suggestion is/was valid.
