Functions

func ConsumeStream 

func ConsumeStream(stream ArtifactStream) error

	// If there are no matching objects stored, empty lists will be returned.
	//
	// If delimited is set to true, SharedPrefix objects will be returned. Doing this is
	// equivalent to asking for a 1 level deep directory search. As an example, if pathPrefix
	// was set to 'foo/', then the directory 'foo/bar' is a possible return value, but
	// not 'foo/bar/baz'. If 'foo/quux' exists and is an object, then it would be returned in the

NOTE: Transact used to move a completed backup into place atomically. This 

assumed that we could do a rename. We now use a blob like api, and
there exists no atomic rename. With the blob api, this changed to
using a status file. Since the status file did not exist before,
a successful backup is one where either there is no status file,
or one where the status file contains 'completed'.
