Unexplained deletions using /Purge

Hello,
I am wondering if anyone else has experienced an issue using EMCOPY64 where files are deleted from the destination location (when they should not be.)

In multiple instances, I am trying to synch the contents of a root level home folder structure (100-180 User Home Folders with anywhere from 5 – 8 TB of data.)

My syntax is: emcopy64.exe \\Source \\Destination /ignoredhsm /nosec /sd /s /d /purge /th 128 /c /r:0 /w:0 /log+:D:\LogFile.txt

When I review the log file, I see that files are often being deleted from certain user home folder structures, when they should not be.

The folders are usually multiple levels deep with a fair amount of very small files.

The specific files and folders continue to exist on the source..but they get deleted from the destination for no apparent reason.

If I modify the script and remove the /Purge switch, the deleted files get copied back.

The issue is, I want to use the /Purge option to keep source and destination in sync for final cut over to the client.

I have changed the /thread option to the default of 64 as well.

I am running the script from a physical 2012 R2 server with a considerable amount of CPU's and memory.

Any help or comments is greatly appreciated.

Thank you
