Transfer data from Windows Server

[revengineer]

After 6 months of gradually building up my server, burning in the hardware, and learning about freenas, I am about to transfer my data (~15 TB) stored in several shares on my windows server to freenas. I am planning to create pool datasets and smb mounts with equal names and transfer them one at a time. Two questions:

1. What is the best and safest way to transfer these data? Should I use "mount_smb" to mount the windows shares on the freenas server and then use "cp -r" to recursively copies those directories? Or should I go another route.

2. Is there a way to verify source against destination files after the transfer?

Advice greatly appreciated.

robocopy from the windows server to the FreeNAS is a pretty safe option.

Bare minimum, use robocopy! But it won’t integrity check the data. To do that you need rsync, which is a trip all on its own..

Thank you both. Right, doing the copy from the windows side works too. Thanks for the reminder and tip. I will look into fciv for the integrity check or possibly opt for a third-party tool such as Beyond Compare. These tools are mentioned in google searches of folks recommending robocopy.

I see a variety of switches suggested for use in robocopy. I will have to sort through which ones make most sense for my situation. If there are recommendations, however, I will gladly take them.
