The 3-2-1 rule was developed to help people and organizations successfully recover data from events such as data corruption, accidental data deletion, physical device failure/loss, or physical damage (such as from fire or flood).
Since its introduction, the 3-2-1 rule has become an industry standard for simple and effective data protection and disaster recovery. Storing multiple copies of data in different locations makes organizations more resilient to cyberattacks because if one copy is damaged, the other copies can be securely protected in another location or on another medium.
Although IT environments have changed significantly since the 3-2-1 rule was first introduced, modern organizations still use this strategy to combat data loss. Unfortunately, this legacy approach to data protection is simply not robust enough to adequately combat modern cyberattacks.
Modern Cyber Attacks and Recovery
Traditional backup methods based on the 3-2-1 rule bahamas mobile database periodic snapshots of data to allow for recovery. However, if a system user accidentally runs malware, the entire network can be compromised, making near-instant recovery impossible.
If, for example, ransomware has deleted or encrypted local backups and snapshots, recovery times can increase dramatically. The organization will only have access to the oldest available backup of the data, which is stored remotely. Therefore, recovery may take longer, and there will likely be fewer recovery points available. This leads to larger data gaps during recovery, which can take hours or even days. Low bandwidth at remote sites can also make data recovery painfully slow.
