Illustration
If your data compresses like the service telemetry capture in our release notes, every petabyte you keep as zpaq -m5 archives shrinks by about 38.1%. At three common storage rates:
| Your storage rate | Bytes removed | Annual reduction |
|---|---|---|
| $0.023 per GB-month | 38.1% of 1 PB | about $105,100 |
| $0.0125 per GB-month | 38.1% of 1 PB | about $57,100 |
| $0.004 per GB-month | 38.1% of 1 PB | about $18,300 |
Illustrative storage rate tiers. The fraction comes from the release-note comparator campaign on a service telemetry capture (measured 2026-09-06, ZJX 1.29.0 compact). An evaluation prices your own data.
Assumptions
- One petabyte is 1,000,000,000,000,000 bytes, billed as 1,000,000 GB; the rate is per GB-month, multiplied by twelve.
- The fraction is 38.1% against the strongest comparator. Data you store uncompressed today saves more: 98.7% against raw on the same capture.
- All retained bytes are structured data such as logs and telemetry.
- Figures are rounded to the nearest hundred dollars.
From ratio to bill
Multiply the size advantage by your eligible bytes and your storage rate. Then subtract compute for creation and verification, temporary space, migration, licensing, and restore costs. How to read a measurement
Your numbers
An evaluation replaces this arithmetic with your bytes and your rate, measured against your current method and the same comparator set. ZJX for business
