Assuming you have an ignite server, just put an entry in cron for make_net_recovery, e.g.:
10 3 * * 0 /opt/ignite/bin/make_net_recovery -x inc_entire=vg00 -s {ignite_IP} > /tmp/mk_nt_rcvy.`date '+%d%m%y'`.log
Obviously you can change this for make_tape_recovery if necessary.
There are many ways you can expand this. For example, I've written a control script which alternates backups between our two ignite servers in different buildings, along with checking availability of the ignite servers and where the last successful backup was taken to.
