I searched in the forums before posting but nothing that was specific to the problem I am experiencing.
I wrote a simple little bash script to create a tar ball of a directory and then copy that tarball to another directory. This is what my script looked like right before I received the error message
tar cjvf /tmp/twiki$TODAY.tar.bz /var/www/html/twiki/data
cp /tmp/twiki$TODAY.tar.bz /mnt/backups/twiki$TODAY.tar.bz
echo "all done"
Now it always returns "tar: error exit delayed from previous errors". Before when I wasn't using $TODAY or $(date) everything was fine. Even when I try and tar the folder manually I get the same error.
