Traditional 3-2-1: Impeding Recovery
Two Plus One Equals Added SecurityAs mentioned above, in the traditional 3-2-1 rule the “2” refers to the number of media types (or devices) you should use onsite. That’s because it’s important to keep your backups as close to your endpoints as possible so your data can be retrieved as quickly as possible if disaster strikes. The last thing you want to worry about is latency or access. As an added layer of security, the "1" in 3-2-1 says that one of those backup locations should be in the cloud or secure storage.
3-2-1-1: Immutable Storage Locks Your Data DownUnfortunately, to some degree, all of your backups are vulnerable to a ransomware attack. That's why IDC recommends a new take on the traditional backup rule: 3-2-1-1, with the extra "1" representing immutable storage. In computing, the dictionary defines immutable as "an object with a fixed structure and properties whose values cannot be changed." Immutability is the key to successful ransomware protection because your data is converted to a write-once, read many times format that can't be altered. Unlike data encryption, there is no key, so there should be no way to "read" or reverse the immutability. Immutability is also key when paired with other data protections, such as continuous data protection, which can capture data on each write at very quick intervals measured in seconds. If that data is then stored in immutable form, with the right technology and good restore and recovery practices, you can access unaltered data within minutes of a breach.
Focus On Business Continuity
A continuum of solutions that covers the whole range of customer needs is hard to find. Arcserve’s recent merger with StorageCraft offers a portfolio of solutions that gives you a clear path to business continuity. Whether it’s an appliance-based solution that combines immutability such as the OneXafe 4400 series, or intrusion detection that uses neural net technology such as Sophos Intercept X Advanced included with Arcserve Unified Data Protection (UDP), these are the kind of solutions needed to meet today’s changing and evolving threats.
One thing is certain: the ransomware threat to data backups is not going away. By focusing on business continuity and following the 3-2-1-1 rule you can be more confident that you can recover your data if an attack is successful. StorageCraft can help you implement a modern approach to 3-2-1-1 for storage, backup, and disaster recovery. Schedule a custom demo today.
