Claim 16:
17. A computer program product for multi-site replication from a single production site, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to perform a method comprising:
capturing, at a gateway node, input/output (“IO”) operations performed on a local filesystem, the local filesystem having mode bits, wherein:
a number of the mode bits is based on a number of target sites; and
wherein one of the mode bits encodes one of a plurality of replication states for each of the remote sites;

enqueuing the captured IO operations onto each of a plurality of queues, wherein each of the plurality of queues is associated with one of a plurality of target sites;
replicating the captured IO operations to each of the plurality of target sites; and
independently tracking a status of the replication of the captured IO operations to each of the plurality of target sites using a current value of one or more of the mode bits.
