Comment 183 for bug 1470250

Thanks for the suggestions @faulpeltz and @Emsi. I was using the Windows Server Backup GUI, which allowed me a maximum of 30 minutes backup intervals.

I now have a Powershell script to kick of one backup after another:

$i=1
while($true)
{
"###################"
"Starting backup $i"
"###################"
wbadmin start backup -quiet -backupTarget:"\\?\Volume{VOLUME_INFO}" -hyperv:"VM_NAME"
"###################"
"Finished backup $i"
"###################"
$i++
}

I'm re-running the test that took 35 hours to reproduce the bug(Commit da1674843 as tip of tree). I hope it causes the bug to trigger much faster. If it does, I'll use this method for testing.

If it still takes a considerable amount of time to reproduce, I'll investigate the snapeshot only method as suggested by @Emsi.
