So, what is blob storage ?
It is slightly different from storing a file on your computer.
In fact, it’s a distributed system.
What that means is that it’s a system that was engineered for availability, reliability, disaster recovery and ease of use.
Just like a car or airplane or any other mission critical systems.
A key feature is this disaster recovery capability which provides backups for the files that you store in the blob storage.
How Does It work ?
When you upload a file to a blob storage, you have an option to specify data redundancy or replication across zones (This will depend on the cloud provider).
What that means is that the cloud vendor is going to take that file you’ve uploaded and make copies of it then put it in their data centers around the world.
So, whenever a disaster strikes in one region, only one data center is affected.
That means only one copy of your data is affected.
While all the other copies in other data centers are not impacted.
This reduces the risk of data loss drastically.
And that’s the power of blob storages.
In fact, this one feature is probably one of the biggest blocks in many of the commonly used services to provide disaster recovery for other storages and databases.
Because who wants to lose critical data or files ?

💡 Note: The pricing and capabilities will be slightly different but the overall offerings should be relatively similar
And that’s it!
If you didn’t know this was possible... well, now you know!
