Can't see previous versions with VSS enabled.

Hi,

I have a W2008R2 with VSS configured and running, I can see shadow copies till today saved in a volume D:, but when I go to see previous versions of a file or directory inside this volume, these previous versions don't appear since 17/11/2014. This date I changed the max value for number os shadow copies via registry editor, but I didn't check previous versions in files and directories later.

I've checked writers with vssadmin command, and all writers are ok. No errors in system logs neither. I've tried restarting VSS service with no result.

Is there any place I can check for solve this?

Regards,

Quique
