Storage tiering and full-text search
Cohesity Alta SaaS Protection search cluster can perform full-text indexing of content, item-level metadata, folders, and access rights. This indexing enables the searchability of all data based on metadata.
Initially, data chosen for the Cool or Archive tiers is stored on the Hot tier to reduce access and transaction charges. This placement facilitates tasks like full-text search, data classification, and using Microsoft Cognitive Services.
Data accessed from the Cool tier remains in the same tier and is not recalled to the Hot tier. Accessing data from the Archive tier first needs to be changed to the Hot or Cool tier from the archive. The Read operations on the Cool tier may incur higher costs. Also, changing the tier, also called rehydration, involves additional Azure costs. Once data is indexed, it remains searchable regardless of the storage tier. To avoid early deletion fees from Azure, it's recommended to maintain data on the Cool tier for a minimum of 30 days and 180 days for the Archive tier.
