Backup RTO/RPO planner
Built for DBAs. Run the read-only size/change sketch, enter recovery model, RPO and RTO targets, get a starting full / differential / log cadence and a rough storage sketch. No email. Nothing is uploaded.
1. Run this read-only query
Needs database file metadata and
msdb backup history
(normal DBA access). Prefer
daily_change_gb_approx
and
log_gb_per_day
when present; if change columns are NULL, estimate change yourself.
2. Enter targets
Starting sketch only — not a runbook for Availability Groups, managed backups, or regulated retention. Change estimates from backup history are approximate. Processed entirely in your browser.
