[SR-Users] Advice on placement of t_replicate (REGISTER)

Hi Guru's, I'd just like some advice on t_replace and its placement in the routing script. A lot of examples show the following setup: save("location"); t_replicate("backup_server"); Would it not be wiser to have something like: if (save("location")) { t_replcate("backup_server"); } Would there be any scenario where you would want to t_replicate if save("location") fails for some reason? The configuration I refer to is if the location database is in memory. I suspect you may want to replicate all if location is going to db core in case of external failure. But would it matter on the placement if the location was in memory? Thanks
