Optimized hash comparison in replication of content addressable storage

1. A computer-executable method for managing replication from a production site to a target site, wherein both the production site and the target site are content addressable data storage systems, the computer-executable method comprising:

processing a replication session from the production site to the target site;

collecting information related to the replication session from the production site to the target site;

analyzing the information to determine whether to change the processing of the replication session bypassing at least one step of the processing of hash based replication to optimize the processing of the replication session; and

wherein the analyzing comprises:

analyzing an amount of times a short hash handle does not exist at the target site; and

if the amount of times does not exceed a threshold, making a positive determination to change the processing of the replication session; and

upon the positive determination, modifying the processing of the replication session by bypassing the sending of the short hash handle and hash signature when processing the replication session; and

analyzing the amount of times the hash signature does not exist at the target site; and

if the amount of times exceeds the threshold, making the positive determination to change the processing of the replication session; and

upon the positive determination, modifying the processing of the replication session by bypassing the sending of the short hash handle when processing the replication session.
