Tar across network

Good afternoon, Managers.

I've got a question. I've got two Solaris 8 boxes. I'd like to be able
to to do tape backups across the local network. The box with the tape
unit is named redstone. The box that needs it's content backed up is
named mercury. I can't attach the tape drive to mercury, no SCSI card
and no budget. I'd really want to avoid running NFS, since these are
outside on the internet. I've been using the following command to run
my backups, but I would like to be able to schedule it (I can't, since
it always asks for a password):

tar cvfb - 20 /var/www/. | ssh redstone dd of=/dev/rmt/0mn obs=20b

I launch this command from mercury. The link between mercury and
redstone is on the local network and is connected via 100/FDX

This command works great, but it won't proceed without a password. Any
ideas on how I could get around the password issue so I could schedule
this via cron?

Thanks in advance.

- Peter
