The 3-2-1-1 Backup Rule: The โExtra 1โ That Could Save Your Business
A stronger backup strategy could be the difference between recovery and shutdown.
๐พ Youโve Heard of 3-2-1โฆ But What About 3-2-1-1?
Most businesses are familiar with the 3-2-1 backup rule, but in todayโs ransomware-driven landscape, thatโs no longer enough.
๐ What the 3-2-1-1 Rule Means:
โ
3 copies of your data (production + 2 backups)
โ
2 different storage types (cloud, local, etc.)
โ
1 offsite backup for disaster recovery
โ
1 immutable or air-gapped copy that cannot be altered or deleted
๐จ Why the โExtra 1โ Matters
Modern cyberattacks donโt just target your systems, they target your backups too. Without an immutable backup, recovery may not be possible.
๐ How This Protects Your Business:
โ
Prevents ransomware from encrypting backups
โ
Ensures clean, recoverable data at all times
โ
Reduces downtime and recovery risk
โ
Strengthens overall business continuity
โ
Adds an extra layer of security against advanced threats
๐ก The Bottom Line
Backup isnโt just about storing data, itโs about ensuring you can recover it when it matters most.
With Sun IT Solutions, your backup and disaster recovery strategy is built to withstand modern threats, including ransomware, system failures, and human error.
One extra layer. Total peace of mind.
