ftopol Posted December 26, 2009 Report Share Posted December 26, 2009 I recently upgraded to V7.7. I am running on Windows XP. I had one successfull backup and then I started getting this error: + Normal backup using Penfold Daily Backup at 12/26/2009 9:55 AM To Backup Set Penfold Daily Backup... MapError: unknown Windows error -1 VssWEnumWriterMetadata: GatherWriterMetadata failed, osErr -1, error -1001 Can't use Open File Backup option for Main (C:), error -1001 ( unknown Windows OS error) The program scans the drive, but then just hangs with no activity. Any help would be appreciated. Quote Link to comment Share on other sites More sharing options...
Mayoff Posted December 26, 2009 Report Share Posted December 26, 2009 Sounds like the VSS service is preventing open file backup from running right. Does the Windows Event Log show any Shadow copy or VSS errors? Quote Link to comment Share on other sites More sharing options...
ftopol Posted December 27, 2009 Author Report Share Posted December 27, 2009 I rebooted and it started working again. Whatever it was seems to have been fixed. The messages in the event viewer just had what I put in my first message. Quote Link to comment Share on other sites More sharing options...
