I'm looking for a way or a software that will create a mirror of my server in real time. I have two identical server. I would also like the same thing for a workstation. I have two identical workstations and i would like to have them mirrored for redundancy purpose. I would like that in real time if possible.

Thank you

RAID 1?

Raid1 is just for the Hard Drive. I'm looking to mirror two server. Mirror the hard drive of both server together and maybe run some sort of load balancing.

Thanx

I guess clustering would do but it is only supported on Enterprise and Data Center. I need something for XP pro and Windows 2003 Server Standard edition

Thanx

Yes clustering is not for standard ed. It has to do with the number of cpu's supported, I think.

Anyway, real time mirror?

Closest you will get with "what's in the box" is DFS. If I remember correctly you can set how often it replicates.
If that doesn't help then just a simple vbs to run robocopy with the /mon (monitor changes) and /mot (monitor time) switches.
Caching of shared drives is another "out the box" solution.

I more formal aproach? Google may be your friend.

I also was looking for a similar solution.

Although mine was not necessary to be in real time.

I used robocopy as a "free" and "low tech" way to replicate data (with the mirror command) to another file server.

it works.

replicates only changed data (after the first replication)

you can output log files to track your failures

i wrote mine to a batch file, schedule it using windows scheduled tasks program.

I mean i'm sure there are much better ways with more administration control etc...

but hey its free, it works for now....buys you time so you can budget for something better.

Have you tried using the /mon and /mot switches?

You want NLB or network load balancing. All you need is an extra NIC in each server and a back end switch.

Clustering would be the right choice, but you need the Enterprise Edition for that. Also WindowsXP does not support redundancy.
