Backup Rotation Planner
Model daily, weekly, and monthly backup retention together so you can size backup storage before policy changes create avoidable cost.
How to read the plan
The retained set count is the total number of recovery points stored across all rotation tiers. Effective size applies the compression ratio to a single backup set before multiplying it by retained copies.
- Use higher monthly retention when compliance or slow-moving incidents drive long restore windows.
- Use compression as a planning adjustment, not as a guaranteed savings figure.
- Review monthly share when older restore points start dominating total capacity.
Where teams get this wrong
Many teams size only daily backups and forget that weekly and monthly snapshots accumulate quietly. This planner makes the long-tail retention cost visible.
- Retention tiers stack; they do not replace one another unless deduplication changes the math.
- Compression varies by workload and should be sampled from real data.
- Restores can slow down if old copies are retained in cheaper storage without clear retrieval expectations.
