1. A method for multi-site replication from a single production site, comprising:
capturing, at a gateway node, input/output (“IO”) operations performed on a local filesystem, the local filesystem having mode bits;
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.
