Copy large amounts of data between network drives.

Hello Experts!

I'm in need of copying a large amount of data between two network drives. Both drives are mounted and I have access to them through explorer. The data consist of pictures, xml documents and such, ordered in a specific order that has to exactly the same way when the copy is done. The amount that i need to copy is about 300G.
My question is:
How do i copy this data safely(NOT CTRL+C, CTRL+V) and can be sure that everything has been copied correctly? I'm I in need of some tool or such?

I usually use freecommander, it is a norton commander clone and is very good at copying. Another utility which specializes at copying is a command line tool, robocopy, but there is also a GUI for it.

First, do not go with copying from some 3rd machine, because in this case all network traffic will be "proxied" through your 3rd machine. Instead, issue copy commands from source or from target computer.
 
To avoid ANY problem, your best bet is to go with Windows Backup on source side, make compressed backup .BKF archive, move archive to target computer, and restore it to proper location. You may also select to restore permissions that way.
Doing so, you you will avoid all problems regarding network connectivity, long file names, special characters in filenames etc.

If you wanna go copy directly, you may use "robocopy" or windows built-in "xcopy" command, for example (from source machine):

xcopy D:\SOURCE \\TARGETMACHINE\TARGETFOLDER /M /E /R /Z /Y

NOTE:
The above command copies network files in restartable mode, clears "Archive" bit for each copied file to 0, so you may reissue command if some error occures, because it will only copy files with "Archive" bit set to 1.

What exactly do you mean by this:

Thanks guys!

leew: I just wanted to make sure that the hierarchy of the files would be the same. Which they were. =)

Wikipedia states that: Robocopy doesn't reliably copy short filenames.
Does anyone have any extra information about this?
Since there is no way I can do a windows backup on the whole structure.
Best regards

I beleive you, but I've seen such problems just few weeks ago, when I was moving files from local D:\ disks to SAN storage E:\ disks. there was about 500 GB of data, I tried with robocopy, xcopy, windows commander, but all of them failed on filenames such this one:

D:\Common files\Service\Drivers\Desktop Products\FSC\CELSIUS M460\FSC_IntelMatrixStorageManagerSATARAIDF6driverd_7601011ProductionVersion_1015117\IntelMatrix_Storage_Manager SATA_RAID_F6_driverdisk_64bit_V7_6_0_1011

Mabe there are some other successfull methods, but I decided to go with Windows Backup which sucessfully backed up and restored data to new location.

But that wouldn't be a short filename, it is rather exactly the opposite, a very long filename, and it includes unknown characters. Long filenames are normally a problem that comes from the OS and it's limitations, and not the copying software.
