This may be dumb, but here it goes

I like to run a full backup. That way if anything happens I only have
to worry about pulling one tape. Well now that my back up is running
out of it's time window I can no longer run full backups ever night. We
are working up a new budget for next year and I was thinking about
getting a server to backup to disk. We currently send last weeks tapes
off site, but how do you do that with backing up to desk? or am I
missing something...

Thanks in advance...
