Solution
Incremental Backup
Back up only what changed at block level so backup runtime tracks change volume, not total disk size.
How It Works
Replicator tracks changed blocks continuously and builds incremental snapshots between full baselines. During backup, only changed ranges are read, deduplicated, compressed, and stored.
Why It Matters
- Shorter backup windows for frequently changing workloads
- Lower network transfer and repository growth
- Consistent protection cycles without full-disk rescans
Operational Notes
Performance depends on changed-data percentage, infrastructure throughput, and policy settings. Incremental chains can be restored directly or merged with parent snapshots when complete state recovery is required.
