We assume that hosting business services in the cloud with a reputable provider will also ensure security of our data. But have you ever read the service agreement? Any cloud service provider will ensure their own platform or infrastructure has necessary backup and security in place to ensure the guaranteed up-time. In terms of your data - unfortunately they will not take any responsibility. When I say data - it's the user's own data that they manage and if incidentally or intentionally if the data gets deleted then it doesn't fall under your cloud service providers jurisdiction to recover them. Is it a shock! Most of my client actually gets a wake-up call when they find this reality.
If you are already on cloud or planning on moving into one then Cloud Backup and Security should definitely be in your check-list. Having the service setup will ensure you can go back in history and recover any data that has been changed or deleted - whether accidentally or intentionally. Depending on your operation it can be setup to backup every hour, day or week. Recently in one of my project - this security solution saved my client from a deliberate mail, calendar and stored data deletion from a rogue employee. Let me secure your cloud investment and you can sleep easy knowing all grounds are covered.
