VSS event log errors

[kevvyb]

Hi

A few months back I started to find that my backups using Mirror Folder were not working using the ntfs change journals. Don't know if this is related to problem this morning though.

I have just tried to back up some files/folders with another application, Macrium Reflect which is now throwing me an error about not being able to create a volume snapshot with error code 0x8004230f.

I have checked the event log and found errors with VSS going back to 02/11/2010. Mainly writer errors until this morning.

This morning I got a different error having reformatted the external drive I was backing up too last night. A catastrophic failure error. See attached vss.txt from windows event log.

I have run 'vssadmin list writers' from command prompt which shows no errors.

I have run chkdsk /f on the reformatted drive which shows ok.

Am continuing to investigate but can anyone give me any ideas as to what I should try first?

Volume Shadow Copy & Truecrypt

Is this the problem?

"The Windows Volume Shadow Copy Service is currently supported only for partitions within the key scope of system encryption (for example, a system partition encrypted by TrueCrypt or a non-system partition located on a system drive encrypted by TrueCrypt). Note: For other types of volumes, the Volume Shadow Copy Service is not supported because the documentation for the necessary API is not available."

...more specifically:

"... because the documentation for the necessary API is available from Microsoft only under a non-disclosure agreement (which is impossible to comply with because TrueCrypt is open source)."

Looks like it's just not possible. Currently investigating how Mirror Folder handles external encrypted (non-system) drives with regard to VSS.
