MongoDB backup plan
I want to switch from MySQL to MongoDB but great data losses (more than 1 hour) are not acceptable for me.
I need to have 3 backup plans:
Hourly backup plan. Data is flushed to disk every X minutes and if something wrong with the server I shall be sure that after reboot it will have all data at least for an hour ago. Can I configure it?
Daily backup plan. Data is synced to backup disk every day so even if server explodes I can recover data for yesterday in some hours. Should I use fsync, master-slave or something else? I would like to have minimal traffic so ideally only changes will be sent.
Weekly backup plan. Data is synced to second backup disk so if both server and first backup disk explode I have at least data for last week. Here this is the question of reliability so it's ok to send all data via network.
How can I do it?
