The blob type built from individual blocks, suited to text and binary files of up to roughly 190.7 TiB; access tiers and object replication work only with this type.

Terms in this definition
- BLOB
Short for binary large object: raw binary data, like pictures, audio, video or documents, that only an application can make sense of. Azure keeps these files as blobs in Blob Storage.
- Object replication
Keeps a destination container in another storage account, in any region, asynchronously in step with a source container's block blobs. It works with GPv2 and premium block blob accounts, requiring versioning on both sides and change feed at the source.
Related terms
- Blob storage
Azure's object store for unstructured content like images and video; a single block blob can reach roughly 190.7 TiB.
- Lifecycle management
Blob Storage policy whose rules delete blobs, or shift them to another access tier, once they reach an age counted from creation, modification, last access or last tier change. GPv2 and legacy BlobStorage accounts support it, as do premium block blob accounts for deletion only.
- Smart tier
Lets Azure decide whether each block blob sits in hot, cool or cold according to usage, with no charges for retrieval, early deletion or tier moves. Archive isn't involved, and the account must be standard general-purpose v2 with zone redundancy.
