I am attempting to migrate a little over 12 TB of data as we move our data center.  In the past we've used and become very proficient with robocopy. However, we found that although we can seed data relatively quickly with robocopy, it is too slow in doing a data refresh. It was suggested that we use emcopy instead.

My initial testing proved out that emcopy is extremely fast when compared to robocopy. However, I've run into a problem with excluding directories.

I need to be able to exclude certain directories from being purged from the destination when doing a refresh.  But although emcopy recognizes my /xd switch and places the information in the "command information" section, it ignores it and purges out the directories on the target anyway.

I found that there were bugs with this function that were fixed in version 4.03 and again in version 4.11, but I'm using the most current version 4.14 and still can't make this work correctly.

Here is one of several commands I've tried as an example:

bin\emcopy D:\Robotest X:\RoboTestEMCOPY /s /o /de /purge /r:1 /w:1 /c /xd "X:\RoboTestEMCOPY\Cisco" /log:"D:\TestRun.log"

This command still ends up deleting the destination directory "Cisco".

I don't believe I have the syntax wrong because emcopy indicates exactly what I expect - that it will ignore the "Cisco" directory. Is there some tick to this or is this yet another bug?
