As we mentioned we should be following the 3-2-1 rule to guarantee the availability and restore of our backups.
For that is a good practice to perform a D2D2T (Disk-to-Disk-to-Tape) or D2D2C (Disk-to-Disk-to-Cloud) strategy.
The D2D2C approach is where the Tape tier of D2D2T is simply replaced with cloud storage.
How it works:
The first stage involves a local backup to disk. For fast backup and fast restore for short-terms recovery operations.
In a second stage you duplicate the backup data to archive off to a cloud-based location. For long-term retention.
As the backup is already in disk it can be transferred to the cloud when there is no impact in production for internet traffic.
The whole point of hybrid cloud backup is to utilize the best of both worlds.
- Improved Availability. As the cloud data can be accessed from any location, improve the accessibility of offsite data when it comes to (DR) Disaster Recovery. Some products can even make the data in the cloud accessible by cloud computing applications in the event of a disaster, thereby making cloud-enabled DR a possibility. With a cloud-based storage solution, the data is instantly available for recovery from anywhere to anywhere. All you need is an Internet connection.
- Easy. For small/medium companies that never considered an offsite strategy because of complexity or price, this can be an easy to implement an affordable solution.
D2D2C addresses the complexity of offsite data protection and seamlessly moves data offsite without requiring additional data copy, tape export, and/or transport activities.
- Affordable solution. That will reduce the cost of ownership. And will be an scalable, pay-as-you-grow alternative.
For many companies their offsite strategy implies the use of tapes.
Hybrid cloud backup (or Disk-to-Disk-to-Cloud) is an alternative, emerging as a viable data backup strategy. Uses your existing on-premise infrastructure and a third-party cloud storage, giving you a highly efficient, scalable and affordable backup and recovery solution.
