PowerSEC uses a chain model to keep backups fast and storage-efficient:
- One full backup as the base (scheduled weekly on plans with scheduled backups)
- Daily differential backups that upload only what changed since that full
- A restore point is the base full plus the differential you pick
Why this model works:
- Lower upload size on large WordPress sites
- Lower timeout risk on shared hosting
- Better storage utilization under package limits
When a new full backup is created instead of a differential:
- The chain is older than the policy window
- The chain has reached its maximum length
- The base full is no longer usable as a differential base
Restore readiness shown in the dashboard is based on Central's backup records and checksum metadata — it is not a guaranteed restore test. The restore itself runs its own safety checks (artifact presence and SHA-256 checksums) before anything is modified.
