When I have conversation with my customers I recommend them to consider Azure storage as a best option to keep their data backup. So the rule of thumb goes up to 30 days data on-prem and rest are on the cloud (at least from my point of view)
All these times for data storage Microsoft had one storage option. But now they have introduced storage type called “Cool blob Storage” Basically this is a type with lower cost when you agree you’re not accessing the data stored on those storage accounts frequently.Example use cases for cool storage include backups, media content, scientific data, compliance and archival data. In general, any data which lives for a longer period of time and is accessed less than once a month is a perfect candidate for cool storage.
- Cost effective: You can now store your less frequently accessed data in the Cool access tier at a low storage cost (as low as $0.01 per GB in some regions), and your more frequently accessed data in the Hot access tier at a lower access cost. For more details on regional pricing, see Azure Storage Pricing.
- Compatibility: We have designed Blob storage accounts to be 100% API compatible with our existing Blob storage offering which allows you to make use of the new storage accounts in existing applications seamlessly.
- Performance: Data in both access tiers have a similar performance profile in terms of latency and throughput.
- Availability: The Hot access tier guarantees high availability of 99.9% while the Cool access tier offers a slightly lower availability of 99%. With the RA-GRS redundancy option, we provide a higher read SLA of 99.99% for the Hot access tier and 99.9% for the Cool access tier.
- Durability: Both access tiers provide the same high durability that you have come to expect from Azure Storage and the same data replication options that you use today.
- Scalability and Security: Blob storage accounts provide the same scalability and security features as our existing offering.
- Global reach: Blob storage accounts are available for use starting today in most Azure regions with additional regions coming soon.
So how to create “Cool Storage”? Well not that big deal you have to log into your Azure portal and then go to “New” and select “Data + Storage” option
Under the storage account “Account kind” select “Blob storage”
After that you should be able to see the “Cool Storage” option,
By the time I’m writing this article sever data backup vendors has already started working with Microsoft to intergrade this feature with their backup products. (CommVault, Veritas NetBackup, SoftNAS, CloudBerry…etc) We would see this list growing really fast.
