Push Data for different database

Hi All,
I have a question. what is the best and safest way to push data from DB01 to DB02
assuming these 2 DBs are same structure.
for example I created data in Item Card in DB01
then i want to be sync every 1 hour to DB02.

options are :
1. export data from DB01, import from DB02
2. use store procedure
3. any other options?

Thanks for any advice
