what does 'file' think the file is - i.e. what does

   file u1_l0_04-29-09_md1.dump

u1_l0_04-29-09_md1.dump:   data

Which I did think was odd.  I had also tried

bzcat u1_l0_04-29-09_md1.dump
bzcat: u1_l0_04-29-09_md1.dump is not a bzip2 file.

but I didn't remember if dump might have it's own headers before the compressed data.


The dump is compressed.  What was the command line you used to create
the dump file?

Have you tried using

   restore tzvf u1_l0_04-29-09_md1.dump

The version of restore that I have under CentOS 6 does not have any compression options except for -l.  Only dump has the compression options and restore is supposed to recognize the compression I believe.  The z option definitely does not work.


Maybe the file is bad.  I am going to look to see if I can find any other backups of that system.


Thank You,

Nataraj
