Claim 8:
9. A system for multi-site replication from a single production site, the system comprising:
one or more processors; and
a memory communicatively coupled to the one or more processors;
wherein the memory comprises instructions which, when executed by the one or more processors, cause the one or more processors 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;

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 inode bits.
