Robocopy is my go-to when I need to move data from server to server while preserving NTFS permissions and other particulars. Well, it has support for multithread file copy but only with Win2k8 or newer systems. If you need to move a whole lot of stuff off a Win2k3 server, that feature is not available. Enter EMCopy which is old system friendly… Also, if there is a retry in the process I can set a flag to check both file size and date to compare what needs to be copied…
emcopy.exe \sourcePath \destinationPath /de /s /th 16 /r:5 /w:45
/de check both the file and date info to compare… only transfer non-existing data
/s copy subdirectories
/th 16 enable threading with 16 (default number of threads is 64, maximum is 256)
/r:5 how many times to retry
/w:45 how long to wait between tries
We use EMC’s Isilon NAS solution here at UNT and I must to say that going to an OS-free file server is pretty refreshing to say the least!
