HEY...now there's a thought! User data and Shared folders on the NAS right? 
It's a Buffalo NAS to it's a little cumbersome to do all the users folders (no 
NTFS support), but each department (only three of them) has its own S: mapping 
and that wouldn't be too tough to set up.

I hadn't thought of that, thanks!

I was thinking more along the lines of taking the file load off the server 
(onto a NAS device) so that it is just running exchange and SharePoint, then 
you could test the backup server at load. You can even then leave the data 
there while you do the swing migration sometime in the future.

I've had their SBS 2K3 on a VM for a long time now (it's on non-R2 Server 2008 
Hyper-V, if that's any indication) and I have confirmed I can stand up the SBS 
VM on VMHOST2 from backups (never have tested external logins or other 
functionality yet though - that's next week). The SATA speed on VMHOST2 is such 
doesn't boot much slower than on VMHOST1, it's performance with more than 5 
folks hooked to it that I am not sure of.

An upgrade to SBS2011 is actually some of the driving force as they already 
have purchased it - I am going to upgrade the VMHOST1 OS to 2008 R2 and the 
vendor that their AR software runs on (Springbrook, and they're scheduled to 
upgrade their software this month as well) recommends with RAID1 or RAID 10 and 
specifically discourages RAID5. Their VMHOST1 server is on RAID5, so I am going 
to add a disk and change to a pair of RAID1 volumes, which requires completely 
flattening the existing Hyper-V config, which also means I need to be REALLY 
comfortable with the DR on their SBS server :). VMHOST2 is a little older 
(PowerEdge SC1435, circa 2007), but still has enough oomph (12GB RAM, a dual 
core AMD Opteron's) to be serviceable.

Once I get the host OS upgraded to R2 I will buy one of the swing kits from 
SBSMIGRATION. I have done a swing migration just once before, and it was 
actually from a standard domain/Exchange onto the SBS 2K3 platform (different 
client).

Q: Can you put a hold on the email flow into the system?
A: Yes, their e-mail hits a Barracuda device first

Q: Can you break the server data into other places i.e. a drive on a NAS box 
which keeps a copy of the user data for while they are switching over?
A: I have a NAS box (but it's not NTFS) as well as VMHOST2. Not fully following 
you here though...

Remember that SBS2K3 is not supported by MS in a virtual environment - but does 
work. Have you considered doing a proper DR practice to see what happens?

You might be in a better position than you think. If you have Shadow Copy on 
the drives and can access the Exchange store then you will have a much smaller 
window of data loss - as long as you can get the raw VM data across.

Can you put a hold on the email flow into the system? Can you break the server 
data into other places i.e. a drive on a NAS box which keeps a copy of the user 
data for while they are switching over?

I would look to planning an upgrade to SBS 2011, if not for now then for soon. 
Take a look at the swing migration options as you are really talking about a 
hardware swing in a DR scenario - you can keep the plates spinning while you 
move what you need to without a major impact.

Sounds like VMHost2 is much older and therefore slower, but an upgrade might be 
cost effective.

I would test the DR option and see if they are happy with performance. You 
could stop email, turn off all machines, run backup, turn off old box, start 
backup box and then start desktops to see how it runs - if enough data is 
cached then it might be fine after a slow logon for users.

Subject: Fun with Hyper-V - and failover hardware Q's

I have a client with SBS 2K3 (VM-SBS1) that's VM'd on a 2K8 (non-R2) server 
(VMHOST1). I now nightly have it shooting backups of VM-SBS1 VHD's to a 2008 R2 
Hyper-V server (VMHOST2) at 6PM. I have the R2 server configured to use these 
disk's as a  VM on it (VM-SBS1-SPARE) and this VM will always be off. Both 
VMHOST servers have local storage only, no SAN. But by doing backups this way 
my thinking is worst case scenario if VMHOST1 or VM-SBS1 get KIA I simply spool 
up VM-SBS1-SPARE and away I go.The worst case scenario is the live servers die 
at 5:58PM and my client loses 1 day of data

While this puts me miles ahead of where I had been (previously the best I had 
was local eSATA backup which takes 3 hours to copy back local), there is the 
not insignificant issue that VMHOST2 has RAID1 SATA drives whereas VMHOST1 has 
RAID5 SAS 15K RPM drives. Performance will suck, and in fact I'm not sure WHAT 
kind of performance this would have with Exchange and SQL and 55 users hooked 
to it. I am assuming it would be better than nothing, but...
How much should I be concerned with performance? I am imagining the worst case 
would be the client has to run on VMHOST2 for a day or two while VMHOST1 gets 
rebuilt (say there's a hardware issue and Dell needs to deliver a part). I am 
thinking  I have 3 options, in increasing order of cost:

1.       Don't sweat it, it's a decent DR option

2.       Upgrade the VMHOST2 drives to SAS drives(~$1000)

3.       Come up with an iSCSI solution (effectively this 
http://garvis.ca/2011/08/30/busting-the-myth-you-cannot-cluster-windows-small-business-server/)
I could probably get them to go with option 2, the caveat here is that server 
is out of warranty although it's not that old (ship date 10/19/07). I will talk 
it over with my client, but also wantde to get your guys'opinions.
