In the first part of this article, you explored different solutions for backing up data on your VPS.
This article will explore the idea of redundancy. Redundant data is not a backup, but can give you a failover in case your primary method of accessing data becomes unavailable.
How you choose to implement replication on your system mostly depends on how you are using your data, what failures you would like to guard against, and what how your visitors are interacting with your server instances.

You mention RAID:
I’d actually pay more if you offered it! hint hint
@Samuel: While we do not support RAID (since we offer <strong>virtual</strong> private servers), all of the hypervisors are on RAID setups.
Aren’t the disks on DO configured with RAID 1 or 5?
@pkseet: All DigitalOcean servers run hardware RAID with different RAID levels, but in each case it requires multiple drive failures at the same time for any data loss to occur.
Concerning the master slave set up. Is replication automatic like the RAID 1? Or do you at a point enable replication? Cause if the former is true then the master slave would inherit the disadvantages of RAID 1 which loses data once deleted from the master DB.
