Billable items

Billable item	Billing rule	Billing cycle	Billing method
Storage usage of Standard LRS objects (Storage)	You are charged based on the total size and storage duration of Standard LRS objects.	You are billed on an hourly basis. Bills are generally generated after a billing cycle ends. The time when bills are generated is determined by the system.	Pay-as-you-go: Storage fees = Storage usage (GB) × Unit price per month/30 (days)/24 (hours). Standard (LRS) storage plan Go to the OSS Resource Plans page and select Standard (LRS) Storage Plan.

Storage usage of Deep Cold Archive LRS objects (ChargedDatasizeDeepCA)	You are charged based on the total size and storage duration of Deep Cold Archive LRS objects. Important Deep Cold Archive objects have a minimum billable size of 64 KB. Objects that are smaller than 64 KB in size are charged as 64 KB.

Resource plan: not supported. SCU: not supported.
Storage usage of IA LRS objects that are stored for less than the minimum storage duration (LessthanMonthDatasize)	If an IA LRS object is overwritten or deleted after it is stored for less than 30 days (720 hours), you are charged for the remainder (720 hours - Actual storage duration) of the minimum storage duration. Note The minimum storage duration (30 days) of IA LRS objects is calculated based on the last modified time of the objects.		Pay-as-you-go: Storage fees = Size of deleted objects (GB) × Unit price per month/30 (days)/24 (hours) × (720 - Actual storage duration). Resource plan: IA (LRS) resource plan. Important OSS calculates the storage usage of IA LRS objects that are stored for less than the minimum storage duration (LessthanMonthDatasize) at a time. If the storage duration of the IA LRS objects is far less than 720 hours, the purchased resource plan can offset only a portion of the storage usage. In this case, a large bill is generated in the next billing cycle (hour) after the IA LRS objects are converted to another storage class or deleted. For example, you stored 10 TB of data as IA LRS data at 06:00 on September 7, 2023. At 06:00 on September 8, 2023, 1 TB of the IA LRS data was automatically or manually moved to another storage class or deleted. In this case, the metering data for this billable item (LessthanMonthDatasize) is 1 TB × (720 - 24) = 696 TB. If you purchase an IA (LRS) storage plan that has a capacity of 10 TB, the following rules take effect: If the bill for the storage usage of IA LRS objects is generated first, the purchased IA (LRS) storage plan can be used to offset the storage fees of 9 TB of IA LRS objects and 1 TB of LessthanMonthDatasize. The excess part of LessthanMonthDatasize (696 TB - 1 TB) is billed based on the pay-as-you-go billing method. If the bill for LessthanMonthDatasize is generated first, the purchased IA (LRS) storage plan can be used to offset the storage fees of 10 TB of LessthanMonthDatasize. The excess part of LessthanMonthDatasize (696 TB - 10 TB) and the storage usage of 9 TB of IA LRS objects are billed based on the pay-as-you-go billing method. SCU: not supported.
Storage usage of IA ZRS objects that are stored for less than the minimum storage duration (LessthanMonthDatasizeZRS)	If an IA ZRS object is overwritten or deleted after it is stored for less than 30 days (720 hours), you are charged for the remainder (720 hours - Actual storage duration) of the minimum storage duration. Note The minimum storage duration (30 days) of IA LRS objects is calculated based on the last modified time of the objects.		Pay-as-you-go: Storage fees = Size of deleted objects (GB) × Unit price per month/30 (days)/24 (hours) × (720 - Actual storage duration). Resource plan: not supported. SCU Every 0.67 GB of SCU capacity can be used to offset the storage fees for 1 GB of IA ZRS objects in the Chinese mainland.
Storage usage of Archive LRS objects that are stored for less than the minimum storage duration (LessthanMonthDatasize)	If an Archive LRS object is overwritten or deleted after it is stored for less than 60 days (1,440 hours), you are charged for the remainder (1,440 hours - Actual storage duration) of the minimum storage duration. Note The minimum storage duration (60 days) of Archive LRS objects is calculated based on the last modified time of the objects.		Pay-as-you-go: Storage fees = Size of deleted objects (GB) × Unit price per month/30 (days)/24 (hours) × (1,440 - Actual storage duration). Resource plan: not supported. SCU: not supported.
Storage usage of Archive ZRS objects that are stored for less than the minimum storage duration (LessthanMonthDatasizeArcZRS)	If an Archive ZRS object is overwritten or deleted after it is stored for less than 60 days (1,440 hours), you are charged for the remainder (1,440 hours - Actual storage duration) of the minimum storage duration. Note The minimum storage duration (60 days) of Archive ZRS objects is calculated based on the last modified time of the Archive ZRS objects.		Pay-as-you-go: Storage fees = Size of deleted objects (GB) × Unit price per month/30 (days)/24 (hours) × (1,440 - Actual storage duration). Resource plan: not supported. SCU: not supported.
Storage usage of Cold Archive objects that are stored for less than the minimum storage duration (EarlyDeletionCA)	If a Cold Archive object is overwritten or deleted after it is stored for less than 180 days (4,320 hours), you are charged for the remainder (4,320 hours - Actual storage duration) of the minimum storage duration. Note Cold Archive objects have a minimum storage duration of 180 days. The minimum storage duration of a Cold Archive object is calculated based on the time when the storage class of the object is converted to Cold Archive.		Pay-as-you-go: Storage fees = Size of deleted objects (GB) × Unit price per month/30 (days)/24 (hours) × (4,320 - Actual storage duration). Resource plan: not supported. SCU: not supported.
