Nearline, Coldline and Archive Storage
The colder storage classes trade a much lower per-gigabyte rate for two things you have to plan around.
They have a minimum storage duration (30, 90, and 365 days) and a retrieval fee. Move data that is genuinely cold and they are dramatically cheaper; read a large share of it every month and the retrieval and operation charges can exceed what you save on storage.
Billed: Per gibibyte-month at progressively lower rates, each with a minimum storage duration and a per-gibibyte retrieval fee.
What triggers this charge
- Objects placed in a colder class by a lifecycle rule or at upload.
- Retrieval fees on every read, copy, move or rewrite, per gigabyte read, which is what makes an over-aggressive lifecycle policy backfire.
- Early-deletion charges when an object is deleted, replaced, or rewritten to another class before its minimum duration: you are billed for the remainder as if it had stayed. A class change made by a lifecycle rule is not a rewrite and is exempt.
How to reduce it
Match the class to real access patterns
Use Storage Insights or access logs before writing a lifecycle rule. What decides it is the share of the data read each month: a gigabyte retrieved from Archive costs more than a month of Standard storage, so reading a large share monthly costs more than leaving it in Standard, while occasional small reads usually do not. The Cloud Storage Class Calculator works out the break-even.
Prefer Autoclass when access is unpredictable
Autoclass reacts to actual access rather than to a guess, and avoids the retrieval fees a manual policy incurs when the guess is wrong.
Respect the minimum durations
Do not move short-lived data into Coldline or Archive. The early-deletion charge means you pay the full minimum period regardless.
