Important

Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

The Upload(Stream, BlobUploadOptions, CancellationToken) operation overwrites the contents of the blob, creating a new block blob if none exists. Overwriting an existing block blob replaces any existing metadata on the blob.

Set access conditions through Conditions to avoid overwriting existing data.

Partial updates are not supported with Upload(Stream, BlobUploadOptions, CancellationToken); the content of the existing blob is overwritten with the content of the new blob. To perform a partial update of the content of a block blob, use the Azure.Storage.Blobs.Specialized.BlockBlobClient.StageBlock(System.String,System.IO.Stream,System.Byte[],Azure.Storage.Blobs.Models.BlobRequestConditions,System.IProgress{System.Int64},System.Threading.CancellationToken) and CommitBlockList(IEnumerable<String>, CommitBlockListOptions, CancellationToken) operations.
