It won't be a true mirror like in a raid, however you can use Robocopy to mirror the two arrays:

robocopy <source> <destination> /MIR /COPYALL /MON:n

/MIR - mirrors the drives
/COPYALL - copys all security descriptors (NTFS file permisisons)
/MON:n - monitors the source for "n" changes and when "n" changes has been reached, copies the changed files to the destination

hi,
strictly speaking mickeyfan answer does not leave doubts!

Known this, in the sense you cannot mirror, that is, synchronize disk2 to disk1 continuosly,

Are you available to come down to compromise ? Take a snaphsot of disk1 on disk2 ?
copyng disk1 image on disk2, stopping server1, put both disks in raid1 on server1 and when sync.ed
break mirror and migrate disk2 on s2 ?

Or, sure going, imaging disk1 on USB disk or il a lan share, then rebuilding disk2 by this image ?

Booted and syspreped s2 at own life, you can shadow a part of s2 (application only)
using ie robocopy or other .

bye

One Server will have Oracle DB, the other one for Citrix , both Servers have 3x300GB raid 5 , but I want to run one of the servers - which has the Oracle - as a file server and save the users documents on the TB drive , so I want to Mirror this drive to the Second Server.

If that is the case why not run a scheduled backup job on each server and have teh backup save it to a seperate server.

You cuold use a third party software. like platespin.

m_jundi,

What are these server going to be used for and this will determine what can be done about any redundency and the such.

There is really no great answer to this question. You can use robocopy to copy this files over to the other server without a prob in a scheduled task.

You would then have to remap any drives that point from the server that died to the live server. There is no automatic process unless you use clustering.

correct me if I am wrong ? cluster will use the whole server, if this is correct we need an extra server, so Oracle DB and Documents will be availabe if one of servers goes Down

Yes clustering will use 2 servers and a storage of some kind.

Check out RSYNC.  I'd also look into simple sync tools.  Are you using Exchange?  If so, these files will be locked and virtually impossible to sync/mirror between the two.

No , we don't use exchange, Files will be only Users documents

Actually, I believe you got 3 or 4 straight answers, all of which are viable options for you.  We are happy to provide you with the options, however we cannot invent new methods out of thin air.  I'm sorry none of use could provide you with an alternative to suite your desires specifically, however each of the options suggested will do what you need to have happen.  I am unaware of any alternatives that have not been mentioned.
