Running CPIO from scripts

When I run CPIO from a script I get an error saying "cpio: write error: No space left on device" but when I run the cpio command from the command line it works. Any ideas what Im doing wrong? Below is the scrip I created and then the command line I ran. I am running both as root. BTW Im using Redhat Enterprise 4

The script:

mt -f /dev/st0 retension
find /data/. >>backuplist
cpio -ov <backuplist >/dev/sd0

The command

cpio -ov <./backuplist >/dev/sd0

Any ideas as to why the script fails but the command line doesn't?

You retension st0 then go to sd0 - tape vs disk. If you're sending to sd0 why are you retensioning st0? Is this a typo in your post or does your script actually contain this? If the latter then that is almost certainly the problem.

Also your script and command line have a slight difference. You leave out the "./" in the script. Are you running the script from the directory that contains the file, backuplist? Are you perhaps running this from cron and assuming it will know where to find backuplist? Were it me I'd specify the full path to where backuplist should be both on the find and on the cpio.

Also as an FYI. The file is unnecessary. You can type:
find /data/. | cpio -ov >/dev/st0

This will pipe the output of the find directly into the cpio command.
