Jon,
I'm afraid I was a little hasty with my emails. Last night, I started
gunzip the file and then went home for the evening. A few hours later,
I ssh'd into my backup server and, upon seeing that the gunzip process had
finished, I issued the file cmd on the unzipped file, which correctly told
me that the file was gnu tar file. Then, as I mentioned in my email last
night, I got the error messages when tried to extract with tar.
HOWEVER, upon returning to the office this morning to my open shell
window (where I started the gunzip before leaving the office last night),
I saw errors:
amanda:/u10# gunzip < sharedata > sharedata.unzipped
gunzip: stdin: invalid compressed data--crc error
gunzip: stdin: invalid compressed data--length error
I apologize. I wrongly assumed that because the gunzip process had
finished last night and that the file cmd saw the output as a gnu tar
file, that all was well. So, should I assume that gzip/gunzip is the
problem here?
Thanks!
Bryan Walton
