Re: Best way to migrate ~ 1 TB of user home folders

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi Mundei,

Regarding your first concern, I think Administrator privilege is required.

Regarding the second concern, I don't think other tool can provide faster
speed. The choke point is the HD transfer speed. Because 1TB is really huge!

Vincent, thanks very much for your quick reply. The clustering bit is
incidental; it's really just copying from one server to another, but
the servers happen to be virtual servers.

There are two problems with ROBOCOPY. Firstly, the permissions issue.
If I'm running a script under my account to ROBOCOPY data across to the
new server, as soon as it reaches the MY DOCUMENTS sub-folders it'll
get access denied. That's because that folder in each user's home
directory is secured with NTFS permissions for LOCALSYSTEM and for
%USERNAME.

Secondly, it's slow. With 1 TB of heavily fragmented data, it's going
to take days. It's also heavily dynamic data. So using ROBOCOPY to
refresh after the initial data load will still take a long time,
stretching well over a day, and we are a 24 x 7 enterprise. My
challenge is to try and manage potential downtime as well as I can.
