What type Azure storage we can use for storing our company old data

@ockyMondal-4133 I would recommend to use Azure Blob Storage, If you are not using the data frequently, If not you can choose Azure File storage

Archive access tier
The archive access tier has the lowest storage cost. But it has higher data retrieval costs compared to the hot and cool tiers. Data must remain in the archive tier for at least 180 days or be subject to an early deletion charge. Data in the archive tier can take several hours to retrieve depending on the priority of the rehydration. For small objects, a high priority rehydrate may retrieve the object from archive in under 1 hour. See Rehydrate blob data from the archive tier to learn more.

Are there specific questions given the info @ https://video2.skills-academy.com/en-us/azure/storage/blobs/storage-blob-storage-tiers?tabs=azure-portal#archive-access-tier ? 180 days isn’t mandatory.

Cool and Archive early deletion
In addition to the per-GB, per-month charge, any blob that is moved to the Archive tier is subject to an Archive early deletion period of 180 days. Additionally, for general-purpose v2 storage accounts, any blob that is moved to the Cool tier is subject to a Cool tier early deletion period of 30 days. This charge is prorated. For example, if a blob is moved to the Archive tier and then deleted or moved to the Hot tier after 45 days, the customer is charged an early deletion fee for 135 (180 minus 45) days of storage in the Archive tier.
