have some very critcal folders and files that are stored on a Windows 2003 server that has drives mapped to a Buffalo Terastation NAS. The issue started because the NAS was having issues and we lost contact with it. I seem to have it back to a state were we can access the data that is on it, but if I plan t redeploy the device, I will need to reconfigure the RAID. In the mean time, I wanted to get our phone call history off of the Windows 2003/NAS share and put it on a Windows 2008r2 server that has it's storage mapped to a much more stable SAN. Friday night I started to copy and paste a 648GB folder from the old server to the new Windows 2008r2 server. The copy ran for hours then ended in error with some "access violation". If I compare the folders the original 2003 folder's properties display "SIZE 648 GB, SIZE on DISK 648 GB, 188,002 Files, 7515 folders. The Windows 2008r2 folder properies displays "SIZE 645 GB, SIZE on DISK 562 GB, Files 187,130, Folders 7503.
I guess I have two main questions.
1. I have noticed if I right click and do properties on any folder in WINDOWS 2008r2, there is a substantial difference between the SIZE and SIZE on DISK and Windows 2003 displays them as almost identical. Is this normal or a setting that has been set?
2. There are 12 folders and over 500 files that did not copy over properly. Is there a way to restart the copy but only attempt to bring over files that did not copy over the first time? Perhaps there is a tool that will let me do a side by side comparison of each folder to show what is missing?
All advice is welcome...thanks
