Slowness with robocopy scripts

[ Edited ]

 

Hello,

 

I have reviewed the logs carefully and noticed the same scripts that run from our soon to retire NAS to the cloud is much faster than when it  is run from the current NAS to NetApp.

 

The logs showed each is file is copied again when in fact the file is already there.  I just removed auto resize on the volume & deduplication but no luck. This is important to me to reduce the time so we can allocate time to cut over to the new NAS (Netapp).

 

 

Old NAS to the cloud:

Robocopy scripts:

 


START ROBOCOPY /PURGE \\fs1\c$\fs\vol0\terminal01 \\aws2\Data$\terminal01 /S /E /W:1 /R:1 /SEC /TEE /LOG:C:\Logs\terminal01.txt

Re: Slowness with robocopy scripts

 

 

I think I found the fix but reluntant since it gave a warning regarding this has to be directed by an NetApp personell.
