Cloud-to-cloud backup, or C2C backup, is the practice of copying data stored on one cloud backup service, to another cloud. Third-party cloud backup has gained popularity with businesses because it takes the management and maintenance of hardware out of the equation. Initial capital expenditures (Capex) for additional hardware are not required, and overall initial costs are lower. Backups can be run automatically and without manual intervention.
C2C backup provides users with a convenient way to store data in multiple locations. However, it also increases the possibility of sensitive information being compromised as compared to offline hard backups.
Pros of cloud-to-cloud backup
Backing up data often falls to the information technology (IT) department for bigger organizations but generally falls to the owner in small businesses. The ability to recover data in its last known good state is important for business continuity (BC). It can be very easy to make a mistake nowadays, so cloud-to-cloud backup is a critical availability element for companies that do business in the cloud.
C2C backup offers a number of advantages over a SaaS vendor’s “native data protection”:
- It is more comprehensive, as it protects the user against many possible cases of data loss.
- A cloud-to-cloud backup provider’s sole focus is on backup data, so backups and recoveries are quicker and easier to perform.
- Data backed up to another cloud is accessible from almost anywhere in the world.
- C2C backups are generally immune to ransomware attacks on an organization because they are not on the office network.
Cloud services are scalable, so backup data sets can grow easily in the storage space. However, organizations need to be careful about the volume of data, as costs will escalate and management will become more difficult. Most if not all management of the backup data falls to the managed service provider.
Data backup can be complex, and an organization needs to make sure it knows exactly what a cloud-to-cloud backup provider is backing up. Additionally, if an organization uses more than one application, it may need a variety of products to back up all of its Cloud data.
Furthermore, bandwidth and latency are always concerns with the cloud. A good internet connection is a must when looking to utilize a cloud backup solution. One way for an organization to gain confidence in its C2C backup strategy is through testing. The same methods used to test backup and recovery for on-premises data should be applied to cloud-to-cloud backups.
