backup of VHDs remotely

We have several VHDs running via Hyper V.

I have heard it's possible to snapshot each every 30 minutes remotely and in the event of disaster (fire) we would be able to mount the VHD on it's remote location, restore the snapshots and only lose 30 minutes worth of work.

How is this accomplished?  What software will we need?

it seems backup excec is a potential software solution, however i'm curious about the remote offsite solutions available and the details behind that.

maybe i'll contact Backup Exec and talk to their sales department

The solution is quite simple, a friend of mine wrote a power shell script to do this:

Power Shell Code: (new-backup-multi.PS1)

Set-ExecutionPolicy unrestricted -force
import-module "C:\Program Files\HyperV_Powershell\hyperv.psd1"
Remove-Item D:\VM-Backup-Script\copy.txt
$arrComps = "Server1", "Server2", "Server3"
Start-Transcript D:\VM-Backup-Script\copy.txt
foreach ($arrComps in $arrComps)
{
invoke-vmshutdown $arrComps -force
new-vmsnapshot $arrComps -force -waitstart-sleep -s 30
Start-VM $arrComps -HeartBeatTimeOut 300

$date = Get-Date -format yyyy-MM-dd
New-Item \\phys-hvb\d$\VM-Drives\$date -type directory -force
Copy-Item D:\VM-Drives\$arrComps\*.vhd \\Remote-Server\d$\VM-Drives\$date\
select-vmsnapshot $arrComps | remove-vmsnapshot -wait -tree -force
invoke-vmshutdown $arrComps -force
start-sleep -s 90
Start-VM $arrComps -HeartBeatTimeOut 300
}
Stop-Transcript

$fileData = (Get-Content "D:\VM-Backup-Script\copy.txt" | out-string)
$file = "D:\VM-Backup-Script\copy.txt"
$smtpServer = "your SMTP relay Server"
$msg = new-object Net.Mail.MailMessage
$att = new-object Net.Mail.Attachment($file)
$smtp = new-object Net.Mail.SmtpClient($smtpServer)
$msg.From = "Your-Server@mail.com"
$msg.To.Add("Recipient@mail.com")
$msg.Subject = "Hyper-V Backup Results"
$msg.Body = $fileData
$msg.Attachments.Add($att)
$smtp.Send($msg)
$att.Dispose()
