1. A system for replication of tags in global scale systems comprising:
one or more processors; and
a non-transitory computer readable medium storing a plurality of instructions, which when executed, cause the one or more processors to:
create a file and a grouping tag for the file;
store the grouping tag in a location in metadata for the file;
retrieve, when preparing for replication, the grouping tag from the location in the metadata for the file;
determine whether a legacy location in the metadata for the file comprises any value which was stored after a most recent replication involving the file;
determine whether a size of the legacy location in the metadata for the file was changed after the most recent replication involving the file, in response to a determination that the legacy location in the metadata for the file comprises any value which was stored after the most recent replication involving the file;
add the grouping tag to the legacy location in the metadata for the file which comprises any value which was stored after the most recent replication involving the file, in response to a determination that the size of the legacy location in the metadata for the file was not changed after the most recent replication involving the file; and
send the metadata for the file, which comprises the grouping tag and any value which are stored at the legacy location in the metadata for the file, to a destination node.
