A backup storage calculator estimates total storage capacity needed for data backups based on data volume, retention period, and change rate. A 3-2-1 backup strategy (3 copies, 2 media types, 1 offsite) typically requires 3–5× the original data volume. Daily incremental backups accumulate to 5–10% of total data volume per week.
