This topic describes the lifecycle management for data storage by changing the data retention period.
Lifecycle management policies
Data must be stored for at least 7 days in the hot storage tier before the data can be moved to the Infrequent Access (IA) storage tier. Data that is stored longer than the data retention period specified for the hot storage tier is automatically moved to the IA storage tier.
Data must be stored for at least 30 days in the hot storage tier before the data can be moved to the Archive storage tier. Data that is stored longer than the data retention period specified for the hot storage tier is automatically moved to the Archive storage tier.
Data must be stored for at least 30 days in the IA storage tier before the data can be moved to the Archive storage tier. Data that is stored longer than the data retention period specified for the IA storage tier is automatically moved to the Archive storage tier.
In pay-by-ingested-data billing mode, you are not charged for data storage within 30 days after the data is written to Simple Log Service. If intelligent tiered storage is enabled, you are charged based on the data retention period and storage tier. For more information, see Billing examples.
