Best Backup Software 2026

Backup software protects data by creating copies of files, databases, applications, and entire systems that can be restored in case of hardware failure, ransomware, accidental deletion, or disaster. Modern backup solutions support local, cloud, and hybrid storage targets with automated scheduling and retention policies. Features include incremental and differential backups to minimize storage and bandwidth, encryption for security, and deduplication to reduce costs. Business continuity features enable rapid recovery with defined RPO (Recovery Point Objective) and RTO (Recovery Time Objective) targets. Cloud-native backup solutions protect SaaS application data that is not covered by provider responsibility models. Effective backup strategy follows the 3-2-1 rule: three copies, two media types, one offsite.
