star: Too few arguments

Hi,

I'm running Debian Etch and want to do regular increment backups with 
star (1.5-67a from debian repo).
I create a snapshot from the logical volume (the root partition /), 
mount it to /mnt/snapshot and dump it with star into a tarfile on a ftp 
server which is locally mounted with the arguments:

star -c -xdev -sparse -acl -xattr-linux -xfflags -link-dirs -j -fifo 
fs=128m artype=exustar dumpdate=/tmp/star_dumpdate -wtardumps -level=0 
f=/mnt/ftp/backup_level-0.star.bz2 -C /mnt/snapshot

After reading the man page and the list archive i thought this would do 
the trick, but star doesn't start the backup and gives me the error message:

star: Too few arguments; will not create an empty archive.
Usage:  star cmd [options] file1 ... filen

Which argument is wrong or missing?


regards,
Thomas Antony
