    Azure Archive Blob Storage Overview

    Azure Archive Blob Storage is the latest addition to Azure’s lineup of storage tiers — Hot and Cool. Archive Blob Storage is designed to serve customers that require long-term data storage at a reasonable price, without the need for immediate data access.

    The name speaks for itself — Archive — and that’s exactly how you should treat it. The data goes in, and then it just stays there for years or perhaps decades. This storage tier is perfect for storing old documents, backups, retired projects, and any data you are legally required to retain long-term.

    Azure Archive Blob is about 80% cheaper than Azure Cool tier and about 95% cheaper than the Hot tier. (Note that prices vary between regions.)

    The data transaction cost is, however, the highest as compared to Hot and Cool tiers. You also have to pay a fee if you delete data from Archive storage, or move it to a different tier, at any time during the first 180 days after you place the data in this tier.

    In order to read data from the Archive tier, you have to "thaw" it first and it can take hours. This is why Archive is not a good choice for short-term backup and disaster recovery datasets. See our guide comparing all Azure access tiers and explaining which tiers to use in different cases:
