Yes, all the bkp* has the same life times:

[root at vpn3 ipsec.d]# ipsec auto --status | grep bkp | grep ike_life
000 "bkp/0x1":   ike_life: 86400s; ipsec_life: 28800s; replay_window: 
32; rekey_margin: 300s; rekey_fuzz: 100%; keyingtries: 3;
000 "bkp/0x2":   ike_life: 86400s; ipsec_life: 28800s; replay_window: 
32; rekey_margin: 300s; rekey_fuzz: 100%; keyingtries: 3;
000 "bkp/0x3":   ike_life: 86400s; ipsec_life: 28800s; replay_window: 
32; rekey_margin: 300s; rekey_fuzz: 100%; keyingtries: 3;
000 "bkp/0x4":   ike_life: 86400s; ipsec_life: 28800s; replay_window: 
32; rekey_margin: 300s; rekey_fuzz: 100%; keyingtries: 3;

It can be a bit problematic as this ipsec instance handle 20+ active 
production connections with different peers/clients. It seems that 
'ipsec whack --name bkp/0xN --debug all,tmi' does not have any logging 
effect. I'm afraid enable debug logging globally will slow down the 
connections and make a huge log.
