Claim 0:
1. A method for replicating data associated with a production site to a replica site, wherein the production site is associated with a production tree and the replica site is associated with a replica tree, the method comprising:
updating leaf nodes of the production tree up to a time related value;
updating leaf nodes of the replica tree up to the time related value;
adding references to leaf nodes that have been updated in the production tree to a first list;
adding references to leaf nodes that have been updated in the replica tree to a second list;
after the leaf nodes of the production tree and the replica tree have been updated, updating other nodes in the production tree and in the replica tree based on the first list and the second list respectively; and
determining that the replica site is synchronized with the production site at the time related value when a top value of the production tree matches a top value of the replica tree.
