as said in many documents, A hash file is created for each partition which contains hashes of each directory in the partition. Replicator continuously examines each partition. Each of three hash file are compared. If hashes are different, Directory that need to be replicated is copied over.

My question is:

 - what is the mean of directory here? Is directory representing account database,container databese and objects?
 - If there is any fault or difference found while comparing the hashes, What is copied over - the whole partition or the particular directory whose hash is different?

Please help me to make it clear.

Thanks in advance
