I'm investigating running regular MySQL dumps to an S3 bucket as part of a disaster recovery strategy (partly spurred by the current zero cost of inbound data transfer!). In the event of a disaster, I would want to restore the dump file from S3 to a new RDS instance. Despite extensive searching, I can't find any examples of this. Does anyone know if this is possible?
To give a bit of context, it's a 500GB write-heavy read-light 24x7 MySQL database. I'm planning to use MySQL replication to a slave, which we can then take dumps from to send to S3 in case of a host failure (we use the same hosting provider for the replication master and slave, although they are in different data centres).
