What you could do is to dump from the remote machine to the main backup
machine. For this to work I work with ssh keys (no password needed).
The example assumes the backup is started from the remote host. But in
principle it can also be initiated from the backup server using ssh.
SRC_SERVER=this_hostname
BAK_SERVER=backup_server
DATE=$(date +%Y%m%d)
dumplevel=0
export RSH=ssh
ssh $BAK_SERVER mkdir -p /backup/${SRC_SERVER}/${DATE}_${dumplevel}
# file needs to exist
backup_file=/backup/somefile
ssh $BAK_SERVER touch ${backup_file}
dump -${dumplevel} -u -z -f $BAK_SERVER:${backup_file}
/dev/VolGroup00/VolGroup00
