CopyBlobIncremental

Copies a snapshot of the source page blob to a destination page blob. The snapshot is copied such that only the differential changes between the previously copied snapshot are transferred to the destination. The copied snapshots are complete copies of the original snapshot and can be read or copied from as usual.

Target container name

The container name of the target page blob. To access the root container, specify $root as the name.

Target relative address

The relative address for the target blob, e.g. folder/subfolder.

Target page blob name

Name of the target page blob. The target of an incremental copy must either not exist, or must have been created with a previous incremental copy from the same source blob. Once created, the blob is permanently associated with the source and may only be used for incremental copies.

Target lease id

Specifies a lease id that must match the lease on a target blob. Required if there is a lease on the blob.

If match target ETag

ETag value for a condition specifying that the given ETag must match target blob's ETag. Do not use simultaneously with If none match ETag or If modified since time.

If none match target ETag

ETag value for a condition specifying that the given ETag must not match target blob's ETag. Do not use simultaneously with If match ETag or If not modified since time.

If target modified since time

Specifies a DateTime value in ISO 8061 format for a condition specifying a time since which the target blob has been modified. Do not use simultaneously with If not modified since time or If match ETag.

If target not modified since time

Specifies a DateTime value in ISO 8061 format for a condition specifying a time since which the target blob has not been modified. Do not use simultaneously with If modified since time or If none match ETag.

Source snapshot uri

The uri of the source page blob which must be a snapshot, must be URL-encoded. The snapshot's blob must either be public or must be authenticated via a shared access signature. The snapshot is copied such that only the differential changes between the previously copied snapshot are transferred to the target.
