Why DRP?
DRP is one of the costly operations in systems life cycle. Not only you need to keep a similar instance of every server and device in your backup site. You also need to make sure that these copies remained in a similar condition to the original one, so when things will get wrong, you could restore.
What Should Have You Done in a Perfect World?
If only your system could work in an Active/Active mode so that every penny you pay will result in another action that results in your bottom line. But till you reach this target, let see how can you keep risks low, and costs affordable as well.
Few Initial Tips:
- Keep your data out side of the applications servers: data should be stored in the database, files should be stored in external storage (Amazon S3) or CDN.
- Replicate your static files (php and etc) using websync.
Keep Performing,
