Not 100% sure about your situation, but when you create a compressed tar archive with 'tar cvzf', you should also pass the 'z' option for viewing the archive: 'tar tvzf'.

If your HPUX tar does not support the 'z' option, first 'gunzip' you file and then 'tar tvf' it.

Hope that helps,
Cheers,

Hi,

If tar -cvzf works, that means "z" option is supported. There is no question of it not working.

maybe the tar -cvzf has not at all worked. check your backup logs.

Well, seeing the command(s):

# tar cvf RADIUS:/dev/nst2 /backup1

Fadia is backing up from one box to another.

Fadia, are the source and target machines both HPUX boxes ? Are you using the same tar on both ?

Cheers,

*cough*

If you are trying to restore on the same machine as you took the backup one, ignore my last message ;-)
