Thanks a lot for your reply Matt :-) Could you please tell how mirror-stream actually works? Does it work sequentially or as changes happen? By sequentially I mean If there are 100 files in the master then mirror-stream copies from file 1 to 100 to the slave so if mirror has passed from 1 to 50 and a change happens in file 25 it will be copied to the slave only after the mirror-stream has completed copying from 50 till 100 and come back to file 25 from the begining. Again what happens if a file in the master and the corresponding file in the slave are identical? Does mirror-stream copy it again or leave it as it is? thanks Siju
