Can someone please recommend the process of 3 tier landscape (dev, qa, prod) with the sandbox and what the best practice should be based on your environment/ or experience to manage or control Backups and Disaster Recovery?
-- That's is basically a 4 tier with a sandbox server, where all the patches etc can be tested without breaking the bank or existing test/qa/prod systems.
I am trying to figure out, when and how we should take backups of each environments (how often), and what would be our disaster recovery approach based on this model.
Thanks.
