Tiering data to cloud or tape storage
You can move data from a directory-container storage pool on disk to cloud or tape storage. The process of moving the data is called tiering. In general, cloud and tape storage can be a cost-effective alternative for storing data that is infrequently accessed and that does not require quick retrieval.
About this task
To schedule tiering, you must define a storage tiering rule. Tiering rules are designed to help you balance the price and performance tradeoffs of disk, cloud, and tape storage for optimized use of the different storage tiers. You can initially back up data to directory-container storage pools, which are defined on disk, to take advantage of the typically faster read and write capabilities of disk storage. Then, you can move the data to tape or cloud storage.
When you define a tiering rule, you must specify an age threshold. Data that meets the specified age threshold is called older data. If you specify a tiering rule for a set of data, you can specify that all of the older data (both active and inactive) is tiered by default. This process is called tiering by age. Optionally, you can specify that only older, inactive data is tiered. This process is called tiering by state. You can also define a tiering rule to ensure that data is excluded from tiering and is kept on disk storage. The data that meets all of your specified requirements for tiering is called eligible data.
