Here is the event log with details. I am running AppAssure backup to create snapshot backups of the server. I am getting this error. THere are only two drives C: and E: so I am not sure why it thinks there is an I:
Event Type: Error
Event Source: AppAssure Logs
Event Category: Core category event
Event ID: 4096
Time: 6:00:42 AM
Source Location: SnapshotHandler.cpp:240
Unable to take VSS snapshot and transfer data for 'C:, E:: Error taking VSS snapshot of volume(s): Failed to get volume GUID for path 'I:' from writer component 'DMSDB1\ALF_ORDER_IMPORT' - The system cannot find the file specified.
Here are some steps I have tried
Ran mountvol.exe and the GUID is not showing up
Checked and is
Checked disk using
ran list volume and I: does
not show up
list writers and no errors
I spoke to App Assure and they worked on it and said I needed to call Microsoft.
Please forgive if this is the wrong board, but any help would be appreciated.

Remote desktop into your home server.
Right click on your C: Drive.
Pick "Configure Shadow Copies"
The C:\ Drive should be highlighted. If not, click on it to highlight it.
Click on the "Settings..." button
In the "Storage Area" section of the Settings window, what does it say in "Located on this volume:"? I suspect that might be your I: reference. BTW - that's the location of the shadow copies that your backup software (as well as the built in backup software) relies on. For home, I have them set to the same hard drive that the snapshots belong to. In busy file servers in a business environment, especially when I want to take snapshots during the day, I'll have that location set to another hard drive - preferably on a different controller/channel to maximize I/O.

C: was set to C: and E: was set to E:
That made sense though....
I am going to disable local shadow copies and see if this doesn't make a change.
Somehow I think there is something corrupted, but before I pay for microsoft support ticket, I want to make sure.....

diabled or not, VSS still relies on them (they are just transparent).
One thing you can do is point the C: snapshots to E: and see if that clears up the error for drive C:
If there is something corrupted, setting it to something different could overwrite the corruption.
Even better, if you have a third disk - even if it's temporarily a USB disk, you could set C: and E: to that third disk. Not only would that reset the path for the shadow copies, but remove any potential disk space issues too.

Aha! From this: http://www.appassure.com/support/KB/4130001/
it sounds like I: is a temporary drive that represets the snapshot and is created for the backup/restore process.
For example, I'm still trying to restore some data from a WHS backup - and while the restore process is running, I temporarily have a Z: drive that the restore wizard creates as part of the restoration process. It represents a mounting of the VSS snapshot I am restoring from.
This post has some general VSS housecleaning tips specific to AppAssure - and right off the bat I recognize a popular conflict (according to the post author): Acronis
Might be worth a look...
sabato 28 luglio 2012 17:16This looks good, I am heading out of town and can hopefully investigate more on Sunday night. Thanks for the effort. Will keep you posted.

Trying these updates now. Will post results later.

Ok, that KB just shows you how to find errors, not much on how to fix them.
Checked VSS settings and you cannot change the path to where they are stored. UNless there is a way to do it through the registry.
venerdì 3 agosto 2012 18:15No luck, about to open a ticket with Microsoft
martedì 14 agosto 2012 18:26I changed the CD ROM to I: and this resolved issue.
not sure if this is best practices, but I am backing up now.
