How to configure snapshots

[burggraf]

Let's say I have 3 nodes on different servers across the internet, and they're all replicating to each other for redundancy. I store the current snapshot on S3, and I can create a new snapshot with -save-snapshot. Now for my questions:

1. How can I configure a snapshot to be updated daily (or even more frequently) so that if a node goes down, it can be quickly brought back online with a relatively-current snapshot.
2. Should all 3 servers create period snapshots? And if so, should they all point to the same S3 bucket location for creating the snapshot, or should they each have a separate location for storing snapshots?

I'm a little confused by the workflow here -- I kind of assume there's a shared location for the snapshot because otherwise how does any node know where to download the snapshot from when you start it up?

Ok, using interval=3600000 seems to update the snapshot every hour, but I'm wondering how many of the nodes should be creating snapshots, and if there's any advantages/disadvantages to having multiple nodes writing snapshots?
