Having a problem backing up Windows 7, need help. Basically, I am having the problem in which the backup will not create at all and fails at the shadow copy. This happens in Windows Backup using both the disk image backup and the personal file backup. It goes to maybe 5%-8% of Shadow Copy depending on the backup type and fails. The error that comes in event viewer is 0x81000019. Yes the disk is brand new and double the size of C:. I tried the fix of making a new 490mb system reserve partition and that did not help (http://social.technet.microsoft.com...l/thread/fce6950d-c06d-4dd0-a850-67022db4fe04) I formatted the disk several times and that didn't help. I tried a third party program, Comodo backup, and that too failed to operate I would say based on the shadow copy service. I tried this fix as well (http://social.technet.microsoft.com...aac-a0af-4740-a331-2b14d604a846?prof=required) and I failed at the regsvr32 es.dll, regsvr32 msxml3.dll, regsvr32 msxml4.dll commands, and WMI Writer when using the vssadmin list writers command was not responding. I've also tried stopping and restarting the service. Besides doing a manual backup using Acronis, which is not preferred at this point, I don't know how to fix this.
