We all feet that heart-dropping moment, when we see the blue screen of death, the file not found error or the phone won't turn on. Our photos, documents, projects can say a year of life vanish in an instant due to hardware failure, ransomware, theft or simple accident.
Welcome to Tactic Tuesday, where we focus on actionable strategies but not on scary stories. This week's tactic is not just a tip but a golden rule followed by IT professionals and experts: The 3-2-1 Backup Rule.
The 3-2-1 backup rule is widely recognized data protection strategy designed to ensure data resilience and recover -ability in the face of various threats including hardware failure, software errors, human errors, ransomware attacks and natural disasters. It recommends maintaining three of your data stored different types of storage media with storing one copy off-site. This approach minimizes the risk of permanent data loss by eliminating single point of failure and providing multiple recovery paths for data.
The three copies consist of the original production data and at least two backup copies. The two different media types ensure protection against media specific failure such as hardware failure or cloud storage outage. The off-site copy of data is critical for disaster recovery and safeguarding data from physical natural events like fires, floods or other local incidents.
Cloud storage is a valid and often recommended option for meeting the off-site requirements. It provides remote, secure storage managed by third-party providers. While the core 3-2-1 rule does not specify a fixed backup frequency, best practices suggest scheduling backups based on criticality and rate of change of the data, with critical data ideally backed up daily or weekly.
The 3-2-1 rule has evolved in response to the evolving modern threats, leading to the enhanced version like 3-2-1-1 rule, which adds the recommendation for an immutable backup copy that cannot be altered or deleted which will provide strong protection against ransomware.
Implementing this 3-2-1 rule involves identifying critical data, setting up backup schedule, choosing diverse storage media and regularly testing the backup and recovery processes to ensure integrity and protection of critical data. This is a strategy considered a foundational guideline for both individuals and organization to protect data.
