Create, list and delete blob snapshots
create_blob_snapshot(container, blob, ...) list_blob_snapshots(container, blob) delete_blob_snapshot(container, blob, snapshot, confirm = TRUE)
container: A blob container.blob: The path/name of a blob....: For create_blob_snapshot, an optional list of name-value pairs that will be treated as the metadata for the snapshot. If no metadata is supplied, the metadata for the base blob is copied to the snapshot.snapshot: For delete_blob_snapshot, the specific snapshot to delete. This should be a datetime string, in the format yyyy-mm-ddTHH:MM:SS.SSSSSSSZ. To delete all snapshots for the blob, set this to "all".confirm: Whether to ask for confirmation on deleting a blob's snapshots.For create_blob_snapshot, the datetime string that identifies the snapshot.
For list_blob_snapshots a vector of such strings, or NULL if the blob has no snapshots.
Blobs can have snapshots associated with them, which are the contents and optional metadata for the blob at a given point in time. A snapshot is identified by the date and time on which it was created.
create_blob_snapshot creates a new snapshot, list_blob_snapshots lists all the snapshots, and delete_blob_snapshot deletes a given snapshot or all snapshots for a blob.
Note that snapshots are only supported if the storage account does NOT have hierarchical namespaces enabled.
