Backup Is Insurance
Data loss destroys businesses. Comprehensive backup strategy ensures survival.
Backup Types
Full backup captures everything. Incremental backs up changes only. Differential backs up since last full. Synthetic full combines incrementals.
The 3-2-1-1 Rule
Three copies of data minimum. Two different storage media. One copy offsite. One copy offline/air-gapped.
Cloud Backup Solutions
Veeam protects virtual environments. Acronis offers comprehensive protection. Carbonite serves small business. AWS Backup centralizes cloud backups.
Local Backup
NAS devices provide network storage. External drives for workstations. Tape for archival compliance. Snapshot for quick recovery.
Backup Scheduling
Continuous backup for critical data. Hourly for active files. Daily for standard operations. Weekly for archival data.
Testing and Validation
Test restores monthly at minimum. Verify data integrity regularly. Document recovery procedures. Time recovery processes.
Ransomware Protection
Immutable backups cannot be encrypted. Air-gapped copies survive attacks. Versioning enables point-in-time recovery. Offline storage is essential.
Recovery Objectives
Recovery Point Objective: maximum acceptable data loss. Recovery Time Objective: maximum acceptable downtime. Balance cost against business impact.
Disaster Recovery
Document procedures thoroughly. Assign roles and responsibilities. Test plans annually. Update based on changes.
