1. A system comprising:
one or more computer readable storage media storing program instructions and one or more processors which, in response to executing the program instructions, are configured to:
create a point-in-time backup of application data stored on both a first datastore and a second datastore, wherein the application data stored on the second datastore is immutable application data,
wherein the program instructions that create the point-in-time backup cause the one or more processors to:
initiate a snapshot of the first datastore;
initiate a suspension of delete operations at the second datastore to preserve the immutable application data stored on the second datastore;
initiate a background copy of the second datastore; and
initiate a resumption of the delete operations at the second datastore in response to completion of the background copy of the second datastore.
